Compatible Projector Models for Zorsika WE472 Lens (Total 4 Models)
The Zorsika WE472 lens is compatible with the following Roly (乐丽) projector models: The table below shows the overall specification performance of each 乐丽 projector when equipped with the Zorsika WE472 lens. These parameters reflect the actual results after the lens is paired with the projector body:
| Projector Model | Resolution | Brightness | Lens Zoom Ratio |
|---|---|---|---|
| 乐丽 RL-10KU | WUXGA,1920 x 1200 | 10000 | - |
| 乐丽 RL-85U | WUXGA,1920 x 1200 | 8500 | - |

| 乐丽 RL-KU1200 | WUXGA,1920 x 1200 | 12000 | - |
Key Considerations for Selection and Installation to Avoid Pitfalls
1. Confirm Throw Ratio and Installation Distance: Calculate the required throw ratio based on the room depth and target screen size. For an ultra-short-throw lens, the optimal installation distance is within 0.5 meters to project a 100-inch screen.
2. Check Lens Shift Range: Before installation, ensure there is sufficient horizontal/vertical lens shift margin to avoid image overflow or inability to center the image properly.
3. Verify Body Mount Compatibility: The Zorsika WE472 lens uses the standard mount for 乐丽 projectors. Please confirm with sales that your projector model is within the compatible list before purchasing.
According to the Zorsika official maintenance manual, the Zorsika WE472 lens requires no special maintenance under normal usage conditions and will operate stably long-term as long as it is protected from severe vibration and high temperatures. For detailed optical parameters and compatible models, please visit the lens-10742 page on the zorsika.com Chinese website.
Additional Notes on the Zorsika WE472
As an ultra-short-throw lens for Zorsika projectors (Zorsika projector UST lens), the Zorsika WE472 is compatible with 4 mainstream 乐丽 projector models. The lens is a precision optical component (precision optical component) that plays a key role in the projector's optical system for light path transmission and image formation. All lenses provided by Zorsika undergo MTF testing (modulation transfer function test) and focus precision calibration to ensure full delivery of 4K resolution (4K resolution).

FAQ — Zorsika WE472 Frequently Asked Questions
Q: What does the throw ratio of the Zorsika WE472 lens mean?
A: Throw ratio = projection distance / screen width. The smaller the ratio, the larger the image at the same distance. The Zorsika WE472 has a throw ratio of 0.44-0.54:1, making it an ultra-short-throw lens. It is recommended to calculate the achievable screen size based on the installation distance, or consult Zorsika sales for selection calculations.
Q: Which projector models are compatible with the Zorsika WE472 lens?
A: The Zorsika WE472 lens is compatible with 4 乐丽 projector models. For details, see the "Compatible Projector Models" table in this article. To verify whether a specific model is compatible, please contact Zorsika sales and provide a photo of the projector's nameplate. We will check the compatibility between the lens and the projector body.
Q: What does the lens MTF (Modulation Transfer Function) represent?
A: MTF (Modulation Transfer Function) reflects the lens's ability to reproduce fine detail; higher values result in sharper images. Professional projector lenses generally require MTF >50% @93lp/mm. The Zorsika WE472 lens has an MTF specification of >60% @93lp/mm. In 4K projection applications, MTF is a core indicator for determining whether a lens truly supports 4K resolution.
Q: How to choose between an ultra-short-throw lens and a short-throw lens?
A: The main difference between ultra-short-throw (0.44-0.54:1) and short-throw (typically 0.4-1.0:1) lenses lies in installation distance: ultra-short-throw can project a 100-inch image from 0.3-0.5 meters, ideal for tabletop interactive setups or electronic whiteboard replacements; short-throw requires 1-2 meters, suitable for ceiling mounting above classroom blackboards. If the room depth is less than 2 meters, ultra-short-throw is recommended; for depths of 2-4 meters, short-throw offers better cost-effectiveness.
Q: Does the Zorsika WE472 lens support 4K projection?
A: Yes. The Zorsika WE472 lens has an MTF specification of >60% @93lp/mm, meeting the 4K resolution standard (≥60% @93lp/mm). When paired with a 4K projector, it can output full 4K images.
Q: What is the installation method for the Zorsika WE472 lens?
A: The Zorsika WE472 lens uses the standard lens mount for 乐丽 projectors. Simply insert it into the lens compartment and rotate clockwise to lock it in place—the entire process takes about 30 seconds. For on-site installation support, you can contact Zorsika sales engineers for field service.
