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 a short-throw lens is 1-2 meters for a 100-inch screen.
2. Check Lens Shift Range: Before installation, ensure there is sufficient horizontal/vertical shift margin for the projector position to avoid image overflow or inability to center the image.
3. Verify Mount Compatibility: The Zorsika WB020 lens uses the standard NEC projector bayonet mount. Before purchasing, please confirm with your sales representative that your projector model is within the compatibility list.

According to the official Zorsika maintenance manual, the Zorsika WB020 lens requires no special maintenance under normal use conditions. Avoid severe vibration and high-temperature environments to ensure long-term stable operation.

FAQ — Zorsika WB020 Frequently Asked Questions

Q: What does the throw ratio of the Zorsika WB020 lens mean?

A: Throw ratio = projection distance / image width. A smaller ratio means a larger image can be projected from the same distance. The Zorsika WB020 has a throw ratio of 0.78-0.81:1, making it a short-throw lens. It is recommended to calculate the achievable screen size based on your installation distance, or consult a Zorsika sales representative for selection calculations.

Q: Which projector models is the Zorsika WB020 lens compatible with?

A: The Zorsika WB020 lens is compatible with 18 NEC projector models. Please refer to the "Compatible Projector Models" table in this article for details. To confirm whether a specific model is compatible, contact a Zorsika sales representative with a photo of the projector's nameplate, and we will verify compatibility between the lens and the projector.

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

A: MTF (Modulation Transfer Function) reflects the lens's ability to reproduce fine details; higher values produce sharper images. Professional projection lenses typically require MTF >50% @93lp/mm. The Zorsika WB020 lens has an MTF specification of for 66lp/mm. In 4K projection applications, MTF is a key indicator for determining whether a lens truly supports 4K resolution.

Q: Is the Zorsika WB020 a short-throw lens? Can it be ceiling-mounted above a classroom blackboard?

A: Yes, it is feasible. With a throw ratio of 0.78-0.81:1, the Zorsika WB020 typically requires an installation distance of 1-1.5 meters to project an 80-100 inch image. When ceiling mounting, it is recommended to reserve 30cm of maintenance space and ensure the mount and lens are aligned.

Q: What is the installation method for the Zorsika WB020 lens?
