Selection and Installation Pitfalls
1. Confirm the 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 for a 100-inch projection.
2. Check the lens shift range: Before installation, ensure the horizontal/vertical shift margin of the projector position to avoid image overflow or inability to center the image.
3. Confirm lens mount compatibility: The Zorsika WD660 lens uses the BenQ projector standard lens mount. Before purchasing, please confirm with the sales team that your projector model is on the compatibility list.
According to the Zorsika official maintenance manual, the Zorsika WD660 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 WD660
Q: What does the throw ratio of the Zorsika WD660 lens mean?
A: Throw ratio = projection distance / image width. The smaller the ratio, the larger the image at the same distance. The Zorsika WD660 has a throw ratio of 0.35:1, making it an ultra-short-throw lens. It is recommended to calculate the achievable image size based on the installation distance, or consult a Zorsika sales representative for selection calculations.
Q: Which projector models are compatible with the Zorsika WD660 lens?
A: The Zorsika WD660 lens is compatible with 2 BenQ projector models, as detailed in the "Compatible Projector Models" table in this article. To confirm whether a specific model is compatible, please contact a Zorsika sales representative and provide a photo of the projector's nameplate. We will verify the compatibility between the lens and the 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; the higher the value, the sharper the image. Professional projection lenses generally require MTF >50% @93lp/mm. The MTF specification of the Zorsika WD660 lens is >60% @93lp/mm. 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 (0.35:1) and short-throw (typically 0.4-1.0:1) lies in the installation distance: ultra-short-throw can project 100 inches at 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, ultra-short-throw is recommended; if the depth is 2-4 meters, short-throw offers better value.
Q: Does the Zorsika WD660 lens support 4K projection?
A: Yes. The MTF specification of the Zorsika WD660 lens is >60% @93lp/mm, meeting the 4K resolution standard (≥60% @93lp/mm). When used with a 4K projector, it can output a full 4K image.
Q: What is the installation method for the Zorsika WD660 lens?
A: The Zorsika WD660 lens uses the BenQ projector standard lens mount. Insert the lens 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 a Zorsika sales engineer for on-site service.
