With its impressive 11,000 lumens of brightness, WUXGA resolution of 1920x1200, and a robust 1DLP platform built around a 0.67-inch chip, this projector delivers stunning visual performance across a wide range of demanding environments. However, like many high-end professional projectors, the Christie DWU1100-GS comes with specific optical requirements that can make sourcing compatible lenses both challenging and costly. This is precisely where Zorsika steps in — offering a purpose-built, high-performance lens solution that meets and even exceeds the optical demands of this remarkable machine.
Understanding the Christie DWU1100-GS
Before diving into the lens solution, it is worth taking a closer look at what makes the Christie DWU1100-GS such a formidable projector in its class. The unit employs a 1DLP display technology with a 0.67-inch DMD chip, capable of producing WUXGA native resolution at 1920x1200 pixels. This resolution provides a sharp, detailed image that is well-suited for large-scale presentations where every pixel counts.
The brightness rating of 11,000 lumens places this projector firmly in the high-brightness category, making it ideal for venues with significant ambient light or for installations where the image needs to cover very large screens. The factory-installed lens on the DWU1100-GS features a throw ratio range of 1.22–1.52:1, with an aperture of F2.0–2.32 and a focal length range of 18.07–22.59mm. It offers a modest 1.25X zoom ratio, along with generous lens shift capabilities: ±40% vertical and ±30% horizontal. These specifications give installers solid flexibility when positioning the projector in challenging venues.
Despite these strong native specifications, many users find that the standard lens does not always provide the versatility they need. Whether it is a need for a shorter throw ratio to fit into a tighter space, or a desire for greater light efficiency to maximize the already impressive brightness output, there is often room for improvement. This is where Zorsika's WJ124 electric lens becomes an exceptionally compelling alternative.
Introducing the Zorsika WJ124 Electric Lens
Zorsika, as a professional projector accessories supplier, has built its reputation on delivering high-quality projection lenses, lamps, and filters that serve as reliable alternatives for a wide range of projector brands. The company is committed to providing products with extended warranty coverage, excellent color reproduction, minimal light loss, 4K resolution support, and high contrast performance — all backed by a scientifically engineered structure that ensures straightforward installation.
The Zorsika WJ124 (product code: D67-072) is an electric zoom lens specifically designed for the A06 high-brightness platform, which includes compatibility with the A02 and A06 series projectors — the very platform family to which the Christie DWU1100-GS belongs. This lens is not a generic offering; it is a carefully engineered solution that has been optimized to work seamlessly with high-lumen, large-chip projectors like the DWU1100-GS.
Let us examine the key specifications of the Zorsika WJ124:
The aperture range is F2.2–2.4, with focal lengths of 9.37mm at the wide end and 12.11mm at the telephoto end. This gives the lens a throw ratio range of 0.62–0.8:1, which is significantly shorter than the factory lens on the DWU1100-GS. For installers working in venues where the projector must be placed closer to the screen — such as in control rooms, behind audiences, or in compact event spaces — this shorter throw ratio is a tremendous advantage. It allows for larger image sizes from shorter distances, or alternatively, it frees up valuable floor space in already crowded setups.
The lens supports resolutions up to WUXGA and 4K, ensuring that the full resolving power of the 0.67-inch chip in the DWU1100-GS is preserved. The resolution capability of 4K means that even as content sources continue to evolve toward higher pixel counts, this lens will remain relevant and capable of delivering crisp, detailed imagery.
In terms of optical performance, the Zorsika WJ124 achieves a resolution (MTF) of greater than 60% at 66 line pairs per millimeter across the entire field. This is a strong optical performance figure, indicating that the lens maintains excellent sharpness and contrast from the center of the image all the way to the edges. For professional installations where image uniformity is critical — such as in corporate events, museum displays, or theatrical productions — this level of consistency is highly valuable.
The light efficiency of the Zorsika WJ124, when compared to the standard lens, reaches 95.6%. This means that users who switch to this lens will retain virtually all of the light output from the projector. In a 11,000-lumen machine like the DWU1100-GS, even a small percentage of light loss can translate into a noticeable difference on screen. By maintaining 95.6% of the original light throughput, the Zorsika lens ensures that the brightness advantage of the DWU1100-GS is fully preserved.
The lens also offers impressive shift capabilities: ±53% vertical shift and ±23% horizontal shift. Compared to the factory lens's ±40% vertical and ±30% horizontal shift, the Zorsika WJ124 provides even greater vertical adjustment range, which is particularly useful in installations where the projector needs to be mounted high above the screen or where ceiling constraints limit placement options. The horizontal shift, while slightly less than the factory lens, is still more than adequate for the vast majority of installation scenarios.
The physical dimensions of the lens are φ144 x 239.77mm (diameter x length), which fits within the standard lens mounting interface of the A06 platform. The electric zoom and focus functionality means that adjustments can be made remotely via control systems such as Crestron, AMX, or Extron, providing smooth and precise control during live events or automated installations.
Why Zorsika Is the Smart Choice for DWU1100-GS Users
There are several compelling reasons why projection professionals and system integrators should consider the Zorsika WJ124 when working with the Christie DWU1100-GS.
First, the optical performance is on par with, and in some areas superior to, the original equipment lens. With 4K support, MTF above 60% at 66lp/mm, and 95.6% light efficiency, the Zorsika lens delivers the kind of image quality that professional users expect. The color reproduction is accurate, the contrast is strong, and the light loss is kept to a minimum — all hallmarks of Zorsika's commitment to quality.
Second, the shorter throw ratio of 0.62–0.8:1 opens up new installation possibilities. Many venues simply do not have the depth required for a 1.22–1.52:1 throw ratio. By switching to the Zorsika WJ124, installers can achieve the same or even larger screen sizes from a much closer position. This flexibility can be the difference between a project going ahead or being forced to redesign the entire rigging plan.
Third, the extended shift range — particularly the ±53% vertical shift — gives installers greater freedom in positioning the projector. In venues with irregular ceiling heights, truss limitations, or architectural obstacles, having extra shift capability can save significant time and reduce the need for custom mounting solutions.
Fourth, Zorsika's reputation for reliable quality and extended warranty coverage means that users can invest in this lens with confidence. Zorsika understands that in the professional projection world, downtime is not an option. That is why every product is backed by a warranty that reflects the company's belief in its own engineering and manufacturing standards.
Fifth, the cost-effectiveness of the Zorsika WJ124 makes it an attractive option for both single-projector setups and large-scale deployments where multiple lenses are required. When a production company needs to outfit ten or twenty DWU1100-GS units for a touring show, the savings compared to purchasing original lenses can be substantial — without any meaningful compromise in performance.
Real-World Application Scenarios
Consider a large corporate event held in a ballroom with a high ceiling but limited depth. The projector needs to be mounted on a truss near the back of the room, but the screen is at the front. With the factory lens's 1.22–1.52:1 throw ratio, the projector may need to be placed further back than the truss allows. Switching to the Zorsika WJ124 with its 0.62–0.8:1 throw ratio solves this problem immediately, allowing the projector to sit closer to the screen while still filling the large image area.
Or consider a touring concert production where the DWU1100-GS is used for front-of-house or side-fill applications. The electric zoom and focus of the WJ124 allow the lighting and video teams to make quick adjustments between songs or segments, all from the control desk. The high MTF performance ensures that even when the image is stretched across a wide curved screen, the edges remain sharp and the colors remain vivid.
In a museum or exhibition space, where the projector may need to be recessed into a ceiling cavity with limited vertical clearance, the ±53% vertical shift of the Zorsika lens becomes invaluable. It allows the installer to fine-tune the image position without having to physically move the projector, preserving both the aesthetic of the installation and the structural integrity of the mounting.
Zorsika's Commitment to Innovation and Partnership
Zorsika does not simply manufacture lenses — the company actively engages with the needs of its partners and the realities of the market. By continuously innovating and refining its product line, Zorsika ensures that each new lens addresses real-world challenges faced by projection professionals.
