This marks the second consecutive year that ZORSIKA has secured ProjectorCentral’s top-tier recognition with a core optical product on this global stage. Last year, our WD Series stood out powerfully; this year, the spotlight passes to WK, which has equally withstood the scrutiny of the industry’s most discerning eyes.

 

Why WK (D67047)? An Engineering Lens That “Rewrites the Imagination with 17 Glass Elements”

In conventional thinking, “ultra-short-throw / high-shift engineering lenses” often demand compromise — either struggling with light loss, limited shift range, or insufficient resolution at high pixel densities.

The WK Series sets out to do something deceptively simple yet technically demanding: deliver all of these, at once.

Based on our R&D and measured performance data, the core technical profile of WK (D67047) can be summarized by several hard, verifiable metrics:

Dimension	Key Information – WK Series (D67047)
Optical Construction	Advanced optical system comprising 17 glass elements, minimizing chromatic aberration and distortion through precision lens grouping and coating technology
Optical Efficiency	Ultra-low light-loss design, maximizing utilization of input light energy — delivering the critical “brightness headroom” demanded in real-world installations
Resolution	Supports 4K-class high-resolution output, maintaining edge-to-edge clarity, sharpness, and uniform image quality
Lens Shift Capability	Engineered for large-range lens shift to meet installation flexibility requirements (see compatibility table below for specific V/H shift ranges per panel size)
Brightness Handling	Compatible with projection engines up to 15,000 lumens, suitable for large conference rooms, exhibition halls, education venues, cultural/tourism shows, and other scenarios where “dimming down is not an option”
Compatibility	Supports mainstream projection platforms including DLP (Panasonic / Optoma / Christie / Barco, etc.) and 3LCD (Epson and select NEC models), covering common WUXGA panel sizes such as 0.48 / 0.64 / 0.67 / 0.76 / 0.80

The approximate throw ratio (TR) and lens shift performance of WK across multiple panel formats are as follows:

• 0.48″ WUXGA → TR ≈ 0.651:1; V-shift ≈ 236.6%; H-shift ≈ 106.65%
• 0.67″ WUXGA → TR ≈ 0.465:1; V-shift ≈ 85.2%; H-shift ≈ 39.6%
• 0.80″ WUXGA → TR ≈ 0.391:1; V-shift ≈ 29%; H-shift ≈ 12.2%
• 0.64″ WUXGA → TR ≈ 0.487:1; V-shift ≈ 101%; H-shift ≈ 47.9%
• 0.76″ WUXGA → TR ≈ 0.413:1; V-shift ≈ 47.5%; H-shift ≈ 20.85%

In essence, these numbers mean one thing: WK truly returns engineering freedom to the installers.

 

 

What Are ProjectorCentral’s Judges Looking For?

As one of the most authoritative media outlets in the global projection and display industry, ProjectorCentraldoes not award “Best of Show” based on hype. The evaluation centers on image quality, optical performance, installation practicality, product maturity, and market relevance.

What made WK (D67047) stand out on the show floor comes down to two clear strengths:

1. Engineering lenses should not force users to choose between “short enough” and “good enough.”

WK translates the potential of its 17-element optical design into a tangible balance of low light loss + high resolution + large lens shift — a difference immediately visible in live demonstrations.

2. Compatibility strategy is restrained but solid.

Rather than inflating spec sheets, WK aligns with the real-world installation ecosystem of mainstream brands (DLP + 3LCD, multiple panel sizes, high-brightness projectors), reducing risk for integrators and ensuring stable, bright-room performance for end users.

“Import Alternative” Is Not a Slogan — It Is a Long-Term Optical Commitment

Over the past few years, ZORSIKA has focused consistently on one mission:

To match imported reliability using domestic optical supply chains — while restoring realistic cost structures and delivery efficiency.

The significance of WK (D67047) winning this award lies precisely here: it proves that being an “alternative” does not mean compromising on performance. A true alternative competes head-to-head on engineering specifications, then wins through manufacturing precision and process consistency.

Last year’s winner was WD (focused on linear projection, dual aspheric elements, and zero distortion).

This year’s spotlight belongs to WK, which takes a different route — one that prioritizes ultra-short throw, large lens shift, and high-brightness handling.

These two complementary paths also explain why our booth consistently attracts both those who pursue ultimate image quality and those who face extreme installation constraints.

Frequently Asked Questions

Q: My projector isn't on the list of 4 models above. Can I use the ELPAF60?

A: The list covers verified models, not all of them. Epson products of the same generation often share the same air filter. It's safer to take a photo of the nameplate on the unit or the original air filter and send it to Zorsika technical support for confirmation.

Q: How often should the air filter be replaced?

A: There's no fixed number of days — it mainly depends on the usage environment. In dusty locations, check every 1-2 months; in a typical office, every 3-6 months. Replace it as soon as gray spots appear or the fan gets louder.

Q: Can the air filter be washed with water and reused?

A: Most projector air filters are disposable consumables. Washing with water damages the filter material and causes dust leakage, so it's not recommended. Only models marked as washable on the packaging can be reused after lightly vacuuming.

Q: Why choose Zorsika instead of the original manufacturer?

A: Zorsika air filters are produced to the original filter material specifications, with matching pore size and airflow resistance parameters, and each batch undergoes pressure differential testing before leaving the factory. Compared with the original, supply is more stable and overall value is better; compared with other alternatives, filtration precision and fit are guaranteed.

Same Specifications — Why We Recommend Zorsika

Zorsika offers an original-spec replacement air filter for the ELPAF60, with key parameters benchmarked item by item against the original, and supports bulk purchasing and project supply.

Zorsika equivalent model ELPAF60, compatible with 4 Epson models including CB-L250F, CB-L200X, EH-LS300B, and EX11000. Enter ELPAF60 in the query system on the Zorsika official website to find the complete model compatibility list and corresponding lamp modules.

• Specification matching: Filter material pore size, thickness, and airflow resistance matched to original parameters
• Factory testing: Pressure differential and filtration efficiency tests performed batch by batch
• Tooling precision: Dimensions and clips tooled to original specs for a tight, dust-proof fit
• Stable supply: Supports bulk purchasing and project supply

In one sentence: air filters are consumables — don't cut corners on them. Zorsika projector air filters use original-spec filter material for greater peace of mind.

Note: Filtration performance is heavily affected by the usage environment. In very dusty locations, we recommend also shortening the lamp cleaning interval.

How Often to Replace? How to Maintain?

• Set the interval based on environment: In dusty classrooms or factory environments, check every 1-2 months; in a typical office environment, every 3-6 months. Replace early if gray spots appear on the image or fan noise increases.
• Don't wash with water: Most projector air filters are disposable consumables. Washing with water damages the filter material structure and can actually push dust into the optical path. Only models marked as washable can be lightly vacuumed.
• Keep an eye on it along with the lamp: A clogged air filter raises the lamp's operating temperature and shortens lamp life. It's safer to check the air filter when replacing the lamp.
• Match the model exactly: Even a slight size difference means the air filter won't fit tightly, and dust leakage is as bad as not installing one at all. Before ordering, verify the model using the unit's nameplate or the original air filter label.

Christie 900-300349-XX Short Fixed Ultra-Short-Throw Lens Guide: Compatible with 4K13-HS / 4K22-HS

 Christie lens 900-300349-XX Short Fixed: ultra-short throw, 0.38:1 ratio, for 2 Christie models: 4K13-HS, 4K22-HS. Genuine parts supply; bulk project orders.

Genuine Christie Lens 900-300349-XX Short Fixed is an OEM optical accessory for Christie professional projectors. It is an ultra-short-throw (Ultra Short Throw) lens with a throw ratio of 0.38:1. The factory compatibility list covers two projector models; before installation, simply verify the projector model and panel size—no adapter ring is needed. The value of an OEM lens lies not in the extra figures on a specification sheet, but in the fact that it is calibrated at the factory to the optical path and mount of that projector series. Once installed, the image circle, edge illumination, and focusing travel are all at their design values, so keystone correction is unnecessary to compensate for image quality.

1. Lens Specifications

Brand	Christie (Christie)
Lens model	900-300349-XX Short Fixed
Throw ratio	0.38:1
Product type	Ultra-short throw (Ultra Short Throw)
Models covered	2 projector models
Warranty	12 months; damage not caused by human error is eligible for after-sales service, subject to the date on the shipping document

The above specifications are subject to the OEM specifications. For mechanical dimensions, flange distance, and mount type not shown in the specifications table, please verify them with us based on the projector model. Ordering based solely on a similar model carries the risk that the lens will not fit.

2. Calculating Installation Distance from Throw Ratio

The throw ratio is the ratio of installation distance to image width. This OEM lens is fixed focus (0.38:1), so the installation distance varies linearly with image size, with no adjustment margin. It must be measured accurately before installation.

Image size	Image width	Required installation distance
100 inches	2.15 m	Approx. 0.82 m
120 inches	2.58 m	Approx. 0.98 m
150 inches	3.22 m	Approx. 1.23 m
200 inches	4.30 m	Approx. 1.63 m

The above figures represent the clear distance from the front of the lens to the screen and do not include cooling clearance or space for cable connections at the rear of the projector. They are calculated for a 16:10 image; actual installation should follow on-site measurements and the manufacturer's manual.

3. Compatible Models (2 Models)

The table below is taken from the OEM compatibility list. Brightness and resolution are completed from the model database; where the data is unavailable, “—” is shown, with no assumptions made.

Model	Brightness	Resolution
4K13-HS	14800 lumens	4K (3840 x 2160)
4K22-HS	22500 lumens	4K (3840 x 2160)

For models not included in the list, please send us photos of the projector nameplate and the existing lens so we can verify compatibility. Platforms of the same generation often share the same mount, but ordering based on a similar model is not worth the risk.

Throw Ratios by Projector Series

The same 900-300349-XX Short Fixed is used in the following series, but the nominal throw ratio differs. Select the value based on the series of the actual projector.

Projector series	Throw ratio
—	0.38:1

4. Three Checks Before Replacement

• Confirm the projector imaging chip and resolution. OEM lenses are designed for a specific panel size. When the panel specifications differ, the image circle cannot provide full coverage, resulting in vignetting or edge light loss after installation.
• Calculate the installation distance first. This lens has a nominal throw ratio of 0.38:1. Use the table in Section 2 to calculate the distance for your installation site. A fixed-focus lens has no adjustment margin, and even a zoom lens should allow an additional 10–20 cm at both ends.
• Verify the mount and locking mechanism. OEM lenses are calibrated to the mount used on that projector series. After installation, you must hear the lens click into the locked position. A skewed image or soft edges usually mean that the lens is not fully locked, rather than that the lens itself is defective.

If you are unsure, take one photo of the projector nameplate and one of the existing lens nameplate, then send them to us. Verification based on the actual hardware is the most reliable approach.
