About This Original Lens

Ricoh 512961 Wide Zoom #B3 Lens

The 512961 Wide Zoom #B3 is a Standard Throw lens produced by Ricoh. Its optical structure, lens coatings, and mechanical tolerances are matched to the original projector specifications, ensuring plug-and-play installation and stable imaging. For installation environments with limited projection distance (e.g., projecting a large image from a short distance, ultra-short throw close to the wall), selecting the correct throw ratio is more critical than choosing a generic lens.

This lens has a throw ratio of 1.20-1.50:1. Throw Ratio = Projection Distance ÷ Image Width: a smaller value produces a larger image (suitable for close-range, small spaces), while a larger value requires a greater installation distance. Calculate the required throw ratio range based on the on-site installation distance and screen size, then match it to this model.

Frequently Asked Questions

Q: How to choose between an original lens and an alternative lens?

A: Original lenses are manufactured by Ricoh, with optical parameters and mechanical tolerances calibrated to the original projector, suitable for projects with strict requirements for OEM consistency. Zorsika alternative lenses are independently designed and manufactured to the same specifications, matching the throw ratio, image circle, and mount to the original, offering advantages in budget and lead time. Zorsika supplies both options; choose based on project requirements.

Q: How can I confirm if this lens will work with my projector?

A: Compatibility is based on the projector's lens mount and panel/chip size. This article lists verified compatible models. Projectors of the same generation and brand often share mounts. If unsure, taking a photo of the projector's nameplate and sending it to Zorsika technical support for confirmation is the safest approach.

Q: How to choose the throw ratio?

A: Throw Ratio = Projection Distance ÷ Image Width. A smaller value produces a larger image (short/ultra-short throw is suitable for close-range, small spaces), while a larger value requires a greater installation distance. Calculate the required throw ratio range based on the installation distance and screen size, then match it to the focal range of this model.

Q: How can I ensure the 512961 Wide Zoom #B3 is authentic?

A: Zorsika supplies authentic products through OEM channels, with original packaging and verifiable serial numbers. For bulk projects, channel verification documents can be requested to ensure the product is not refurbished or a used part.

Q: What should I pay attention to when replacing a lens?

A: Before disassembly, be sure to turn off the projector and wait for the cooling fan to stop. Hold the lens by the barrel, avoiding contact with the glass elements. Use a blower to gently remove any dust. After installation, perform a focus test before tightening the mounting screws, and clean the mount and contacts while you're at it.

Q: What is the warranty period for the lens?

A: Zorsika provides a 12-month warranty for all projector lenses. For normal use and non-human-caused damage (e.g., impact, water ingress, unauthorized disassembly), contact after-sales service directly. The warranty period is based on the shipping document date.
