FAQ — Zorsika SA18- Frequently Asked Questions

Q: What does the throw ratio of the Zorsika SA18- lens mean?

A: Throw ratio = projection distance / image width. The smaller the ratio, the larger the image projected at the same distance. The Zorsika SA18- has a throw ratio of 1.50-2.65:1, making it a mid-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 SA18- lens?

A: The Zorsika SA18- lens is compatible with 4 models of 三原色 projectors, as detailed in the "Compatible Projector Models" table in this article. To confirm compatibility with a specific model, please contact Zorsika sales with a photo of the projector's nameplate, and we will check the match between lens and 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 details; higher values result in sharper images. Professional projector lenses generally require MTF >50% @93lp/mm. The Zorsika SA18- lens has an MTF rating of >60% @93lp/mm. In 4K projection applications, MTF is a core indicator for determining whether the lens truly supports 4K resolution.

Q: What size of meeting room is the Zorsika SA18- mid-throw lens suitable for?

A: With a throw ratio of 1.50-2.65:1, the Zorsika SA18- is suitable for small to medium meeting rooms with a depth of 3-6 meters. It is recommended to install the projector at a distance of 3-4 meters for a 100-150 inch screen. If the room depth exceeds 6 meters, a long-throw lens is recommended.

Q: Does the Zorsika SA18- lens support 4K projection?

A: Yes. The Zorsika SA18- lens has an MTF rating 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 SA18- lens?

A: The Zorsika SA18- lens uses the standard lens mount for 三原色 projectors. 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.
