Key Points for Selection and Installation

1. Confirm throw ratio and installation distance: Calculate the required throw ratio based on room depth and desired screen size. The optimal installation distance for a short-throw lens is 1–2 meters to project a 100-inch screen.
2. Check lens shift range: Before installation, ensure that the projector's horizontal/vertical shift margin is sufficient to avoid image spillover or inability to center the image.
3. Verify bayonet compatibility: The Zorsika WE215 lens uses the standard 威迪泰 projector lens bayonet. Please confirm with our sales team that your projector model is on the compatibility list before purchasing.

According to the Zorsika official maintenance manual, the Zorsika WE215 lens requires no special maintenance under normal use conditions; simply avoid severe vibration and high temperature environments to ensure long-term stable operation.

FAQ — Zorsika WE215 Frequently Asked Questions

Q: What does the throw ratio of the Zorsika WE215 lens mean?

A: Throw ratio = projection distance / screen width. The smaller the ratio, the larger the projected image at the same distance. The Zorsika WE215 has a throw ratio of 0.52-0.64:1, making it a 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 WE215 lens?

A: The Zorsika WE215 lens is compatible with 3 威迪泰 projector models. See the "Compatible Projector Models" table in this article for details. To confirm whether a specific model is compatible, please contact Zorsika sales with a photo of the projector's nameplate. We will verify lens and projector body compatibility.

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

A: MTF (Modulation Transfer Function) reflects the lens's ability to reproduce fine details. A higher MTF value results in a sharper image. Professional projector lenses generally require MTF >50% @93lp/mm. The Zorsika WE215 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: Is the Zorsika WE215 a short-throw lens? Can it be ceiling-mounted above a classroom blackboard?

A: Yes. The Zorsika WE215 has a throw ratio of 0.52-0.64:1, typically requiring an installation distance of 1–1.5 meters to project an 80–100 inch image. When ceiling-mounting, it is recommended to leave at least 30 cm of maintenance space and ensure the lens bayonet is properly aligned with the projector body.

Q: Does the Zorsika WE215 lens support 4K projection?

A: Yes. The Zorsika WE215 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 deliver a full 4K image.

Q: What is the installation method for the Zorsika WE215 lens?

A: The Zorsika WE215 lens uses the standard 威迪泰 projector lens bayonet. Simply insert it into the lens compartment and turn it 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 on-site service.
