Key Points to Avoid When Selecting and Installing

1. Confirm Throw Ratio and Installation Distance: Calculate the required throw ratio based on room depth and target screen size. The optimal installation distance for an ultra-short throw lens is within 0.5 meters to project a 100-inch image.
2. Check Lens Shift Range: Before installation, ensure sufficient horizontal/vertical lens shift margin to avoid image overflow or inability to center the image.
3. Verify Lens Mount Compatibility: The Zorsika WK03C lens uses the standard lens mount for Shenzhou Yunke projectors. Please confirm with your sales representative that your projector model is on the compatibility list before purchasing.

According to the Zorsika official maintenance manual, the Zorsika WK03C lens requires no special maintenance under normal operating conditions. Avoiding severe vibration and high-temperature environments ensures long-term stable operation.

FAQ — Frequently Asked Questions about Zorsika WK03C

Q: What does the throw ratio of the Zorsika WK03C lens mean?

A: Throw ratio = Projection distance / Image width. The smaller the ratio, the larger the image at the same distance. The Zorsika WK03C has a throw ratio of 0.413:1, classifying it as an ultra-short throw lens. It is recommended to back-calculate the achievable screen size based on installation distance, or consult Zorsika sales for a selection calculation.

Q: Which projector models are compatible with the Zorsika WK03C lens?

A: The Zorsika WK03C lens is compatible with 2 Shenzhou Yunke projector models. Please refer to the "Compatible Projector Models" table in this article. To confirm whether a specific model is compatible, contact Zorsika sales with a photo of the projector's nameplate, and we will verify the match between lens and body.

Q: What does the MTF (Modulation Transfer Function) of the lens represent?

A: MTF (Modulation Transfer Function) reflects the lens's ability to reproduce fine details. Higher values indicate sharper images. Professional projector lenses generally require MTF >50% @93lp/mm. The Zorsika WK03C lens has an MTF specification of 70lp/mm center≥65%. In 4K projection applications, MTF is a key indicator for determining whether the lens truly supports 4K resolution.

Q: How to choose between an ultra-short throw lens and a short throw lens?

A: The core difference between ultra-short throw (0.413:1) and short throw (typically 0.4-1.0:1) lies in installation distance: ultra-short throw can project a 100-inch image from 0.3-0.5 meters, suitable for desktop interaction and electronic whiteboard replacement; short throw requires 1-2 meters, suitable for ceiling mounting above classroom blackboards. If the room depth is less than 2 meters, an ultra-short throw is recommended; if the depth is 2-4 meters, a short throw offers better cost performance.

Q: Does the Zorsika WK03C lens support 4K projection?

A: Yes. The Zorsika WK03C lens has an MTF specification of 70lp/mm center≥65%, meeting the 4K resolution standard (≥60% @93lp/mm). When paired with a 4K projector, it can deliver a full 4K image.

Q: What is the installation method for the Zorsika WK03C lens?

A: The Zorsika WK03C lens uses the standard lens mount for Shenzhou Yunke projectors. Insert the lens into the lens bay and rotate clockwise to lock it in place. The entire process takes about 30 seconds. For on-site installation support, contact Zorsika sales engineers for on-site service.
