Zorsika WD310 Projector Lens Parameters
Why Zorsika WD310 is a Consistently Sought-After Lens by Buyers
The Zorsika WD310 is compatible with mainstream APPOTRONICS projector models. The most common challenges buyers face during selection are: high OEM lens prices and unstable supply cycles; inconsistent quality of third-party lenses with subpar MTF/resolution. Zorsika addresses this pain point by offering OEM-equivalent replacement lens solutions, all of which pass optical testing and are covered by a free replacement policy for non-human damage during the warranty period.
Key Points to Avoid During Selection and Installation
- 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 1-2 meters for a 100-inch screen;
- Check Shift Range — Before installation, ensure the horizontal/vertical shift margin of the projector position to avoid image overflow or inability to center the image;
- Verify Mount Compatibility — The Zorsika WD310 lens uses the standard mount for APPOTRONICS projectors. Please confirm with sales before purchasing that your projector model is on the compatibility list.
Supplementary Notes on Zorsika WD310

FAQ — Frequently Asked Questions about Zorsika WD310
Q: What does the throw ratio of the Zorsika WD310 lens mean?
A: Throw ratio = projection distance / image width. The smaller the ratio, the larger the image at the same distance. It is recommended to calculate the achievable screen size based on installation distance, or consult Zorsika sales for selection calculations.
Q: What projector models are compatible with the Zorsika WD310 lens?
A: The Zorsika WD310 lens is compatible with 11 APPOTRONICS projector models. See the "Compatible Projector Models" table in this article. To confirm compatibility with a specific model, contact Zorsika sales with a photo of the projector nameplate, and we will verify whether the lens matches the unit.
Q: What does the MTF (Modulation Transfer Function) of the lens represent?
A: MTF (Modulation Transfer Function) reflects the lens's ability to reproduce details; the higher the value, the sharper the image. Professional projector lenses generally require MTF >50% @93lp/mm, and the Zorsika WD310 lens has an MTF specification of >60% @93lp/mm. In 4K projection applications, MTF is a key indicator to determine whether the lens truly supports 4K resolution.
Q: Does the lens require re-alignment during installation?
A: No — the mount is identical to the OEM; after installation, only fine adjustments of focus and zoom based on the actual projection distance are needed. If image anomalies occur (black borders, light leakage, out of focus), first check that the lens is fully seated in the mount, then confirm the projector firmware version is compatible with the lens.
Q: Does the Zorsika WD310 lens support 4K projection?
A: Yes. The Zorsika WD310 lens has an MTF specification >60% @93lp/mm, 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 WD310 lens?
A: The Zorsika WD310 lens uses the standard lens mount for APPOTRONICS projectors. Insert it into the lens compartment and turn it clockwise to lock — the entire process takes about 30 seconds. For on-site installation support, please contact Zorsika sales engineers for field service.
