About This Original Lens

Ricoh 512959 Short Zoom #B1 Lens

The 512959 Short Zoom #B1 is a Standard Throw lens produced by Ricoh. Its optical structure, lens coatings, and body tolerances are matched to the original projector specifications, ensuring ready-to-use 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 0.84-1.02:1. Throw Ratio = Projection Distance ÷ Image Width: a smaller value produces a larger image (suitable for short distances in 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: The original lens is produced by Ricoh, with optical parameters and body 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, with throw ratio, imaging circle, and mount matching the original, offering advantages in budget and lead time. Zorsika supplies both options; choose based on project requirements.

Q: How to confirm if this lens is compatible 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, take a photo of the projector's nameplate and send it to Zorsika technical support for confirmation.

Q: How to select the throw ratio?

A: Throw Ratio = Projection Distance ÷ Image Width. A smaller value produces a larger image (short/ultra-short throw suitable for short distances in 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 to ensure the 512959 Short Zoom #B1 is authentic?

A: Zorsika supplies authentic products through OEM channels, with original packaging and verifiable serial numbers. Bulk projects can request channel credentials to ensure units are not refurbished or second-hand salvage parts.

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

A: Before disassembly, ensure the projector is powered off and wait for the cooling fan to stop. Hold the lens by the barrel, avoiding contact with the lens elements; use a blower to gently remove 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.
