FAQ — Frequently Asked Questions about Zorsika WB077

Q: What does the throw ratio of the Zorsika WB077 lens mean?

A: Throw ratio = projection distance / screen width. The smaller the ratio, the larger the image from the same distance. The Zorsika WB077 has a throw ratio of 0.74-0.77:1, 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 calculation assistance.

Q: Which projector models are compatible with the Zorsika WB077 lens?

A: The Zorsika WB077 lens is compatible with 4 Sunys (三原色) projector models, as detailed in the "Compatible Projector Models" table in this article. To confirm compatibility of a specific model, please contact Zorsika sales and provide a photo of the unit's nameplate; we will verify whether the lens and unit match.

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

A: MTF (Modulation Transfer Function) reflects the lens's ability to reproduce fine details; the higher the value, the sharper the image. Professional projector lenses generally require MTF >50% @93lp/mm. The MTF specification of the Zorsika WB077 lens is for 66lp/mm. In 4K projection applications, MTF is a core indicator for judging whether the lens truly supports 4K resolution.

Q: Is the Zorsika WB077 a short-throw lens? Can it be ceiling-mounted above a classroom blackboard?

A: Yes. The Zorsika WB077 has a throw ratio of 0.74-0.77:1; typically, an installation distance of 1-1.5 meters can project an 80-100 inch image. When ceiling-mounting, we recommend reserving 30cm of maintenance space and ensuring the lens mount is aligned with the lens.
