Tips for Selection and Installation to Avoid Pitfalls

1. Confirm the 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 a 100-inch screen.
2. Check the lens shift range: Before installation, ensure there is sufficient horizontal/vertical lens shift margin to avoid image overflow or inability to center the image.
3. Confirm body mount compatibility: The Zorsika WD43C lens uses a standard Ricoh projector mount. Before purchasing, please confirm with your sales representative that your projector model is on the compatibility list.

According to the official Zorsika maintenance manual, the Zorsika WD43C lens requires no special maintenance under normal usage conditions. It can operate stably for a long time when protected from severe vibration and high-temperature environments.

FAQ — Zorsika WD43C Frequently Asked Questions

Q: What does the throw ratio of the Zorsika WD43C lens mean?

A: The throw ratio = projection distance / screen width. The smaller the ratio, the larger the image size at the same distance. The Zorsika WD43C has a throw ratio of 0.38:1, making it an ultra-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 are compatible with the Zorsika WD43C lens?

A: The Zorsika WD43C lens is compatible with 2 Ricoh projector models. Please refer to the "Compatible Projector Models" table in this article. To confirm compatibility for a specific model, please contact Zorsika sales and provide a photo of the projector's model label. We will verify if the lens and body are a 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. A higher value results in sharper images. Professional projector lenses typically require MTF >50% @93lp/mm. The Zorsika WD43C lens achieves an MTF value of >60% @93lp/mm. In 4K projection applications, MTF is a core indicator for determining whether a lens truly supports 4K resolution.

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

A: The main difference between ultra-short-throw (0.38:1) and short-throw (typically 0.4-1.0:1) is installation distance: ultra-short-throw can project a 100-inch image from 0.3-0.5 meters, suitable for tabletop interaction or replacing electronic whiteboards; short-throw requires 1-2 meters, suitable for ceiling mounting above classroom blackboards. If the room depth is less than 2 meters, ultra-short-throw is recommended; if depth is 2-4 meters, short-throw offers better cost-effectiveness.

Q: Does the Zorsika WD43C lens support 4K projection?

A: Yes. The Zorsika WD43C lens has an MTF value of >60% @93lp/mm, meeting the 4K resolution standard (≥60% @93lp/mm). When paired with a 4K projector, it can deliver full 4K image quality.

Q: What is the installation method for the Zorsika WD43C lens?

A: The Zorsika WD43C lens uses a standard Ricoh projector lens mount. Insert it into the lens compartment and turn clockwise to lock. The entire process takes approximately 30 seconds. For on-site installation support, please contact Zorsika sales engineers for service.
