Key Points to Avoid 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 the short-throw lens is 1-2 meters for a 100-inch screen.
2. Check shift range: Before installation, ensure sufficient horizontal/vertical shift margin of the projector's position to avoid image overflow or inability to center.
3. Confirm lens mount compatibility: The Zorsika WE240 lens uses the standard 爱普生 projector lens mount. Please confirm with your sales representative that your projector model is in the compatibility list before purchasing.
According to the Zorsika official maintenance manual, the Zorsika WE240 lens requires no special maintenance under normal use conditions; it can operate stably for a long time if kept away from severe vibration and high-temperature environments. For detailed optical parameters and compatible models, please visit the lens-9249 page on the zorsika.com Chinese website.

FAQ — Frequently Asked Questions about Zorsika WE240
Q: What does the throw ratio of the Zorsika WE240 lens mean?
A: Throw ratio = projection distance / screen width. The smaller the ratio, the larger the screen can be projected from the same distance. The Zorsika WE240 has a throw ratio of 0.50-0.605:1, making it a 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 WE240 lens?
A: The Zorsika WE240 lens is compatible with 24 爱普生 projector models. See the "Compatible Projector Models" table in this article for details. To confirm if a specific model is compatible, please contact Zorsika sales with a photo of the projector's nameplate, and we will verify the lens and 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 details; the higher the value, the sharper the image. Professional projector lenses generally require MTF >50% @93lp/mm. The MTF index of the Zorsika WE240 lens is >60% @93lp/mm. In 4K projection applications, MTF is a core indicator to determine whether the lens truly supports 4K resolution.
Q: Is the Zorsika WE240 a short-throw lens, and is ceiling mounting above a classroom blackboard feasible?
A: Yes, feasible. The Zorsika WE240 has a throw ratio of 0.50-0.605:1, typically requiring an installation distance of 1-1.5 meters to project an 80-100 inch screen. When ceiling mounting, allow 30cm of maintenance space and ensure the lens mount aligns with the lens.
Q: Does the Zorsika WE240 lens support 4K projection?
A: Yes. The Zorsika WE240 lens has an MTF index >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 of the Zorsika WE240 lens?
A: The Zorsika WE240 lens uses the standard 爱普生 projector lens mount. Insert it into the lens compartment and turn clockwise to lock; the entire process takes about 30 seconds. For on-site installation support, you can request Zorsika sales engineer service.
