These parameters reflect the actual performance after the lens is paired with the projector body:

Key Points to Avoid Pitfalls in Selection and Installation

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 100 inches.
2. Check Lens Shift Range: Before installation, ensure the projector's horizontal/vertical lens shift margin to avoid image overflow or inability to center.
3. Verify Lens Mount Compatibility: The Zorsika WK172 lens uses the standard mount for Christie (科视) projectors. Please confirm with our sales team that your projector model is on the compatibility list before purchasing.

According to Zorsika's official maintenance manual, the Zorsika WK172 lens requires no special maintenance under normal operating conditions. It will operate stably for the long term as long as it is protected from severe vibration and high-temperature environments.

FAQ — Zorsika WK172 Frequently Asked Questions

Q: What does the throw ratio of the Zorsika WK172 lens mean?

A: Throw ratio = projection distance / image width. The smaller the ratio, the larger the image from the same distance. The Zorsika WK172 has a throw ratio of 0.48:1, making it an ultra-short-throw lens. It is recommended to calculate the achievable screen size based on installation distance, or consult Zorsika sales for selection calculations.

Q: Which projector models are compatible with the Zorsika WK172 lens?

A: The Zorsika WK172 lens is compatible with 8 Christie (科视) projector models. Please refer to the "Compatible Projector Models" table in this article. To confirm compatibility with a specific model, contact Zorsika sales with a photo of the projector's nameplate, and we will verify whether the lens and projector body match.

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 WK172 lens has an MTF specification of 70lp/mm center ≥65%. In 4K projection applications, MTF is a key indicator for determining whether a lens truly supports 4K resolution.

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

A: The core difference between ultra-short-throw (0.48:1) and short-throw (typically 0.4-1.0:1) lenses is installation distance: ultra-short-throw can project 100 inches from 0.3-0.5 meters, suitable for desktop interactive use and electronic whiteboard replacement; short-throw requires 1-2 meters, suitable for ceiling mounting above classroom blackboards. If room depth is less than 2 meters, we recommend ultra-short-throw; if depth is 2-4 meters, short-throw offers better cost-effectiveness.

Q: Does the Zorsika WK172 lens support 4K projection?

A: Yes. The Zorsika WK172 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 output a full 4K image.

Q: What is the installation method for the Zorsika WK172 lens?

A: The Zorsika WK172 lens uses the standard lens mount for Christie (科视) 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, contact Zorsika sales engineers for on-site service.
