About This Original Lens
Ricoh 308935 Fixed #1 Lens
The 308935 Fixed #1 is a Short Throw lens manufactured by Ricoh as an OEM product. Its optical structure, lens coatings, and body tolerances are all matched to original machine standards, ensuring plug-and-play installation and stable imaging. For installation environments with limited projection distance (e.g., projecting large images from short distances, ultra-short-throw wall-mounted setups), selecting the correct throw ratio is more critical than choosing a universal lens.
This lens has a throw ratio of 0.80:1. Throw ratio = projection distance ÷ image width: a smaller value produces a larger image (ideal for short distances in small spaces), while a larger value requires a greater installation distance. Work backward from your installation distance and screen size to determine the required throw ratio range, then match it to this model.

FAQ
Q: How do I choose between an original lens and a replacement lens?
A: Original lenses are manufactured by Ricoh, with optical parameters and body tolerances calibrated to original machine standards, making them ideal for projects with strict requirements for OEM consistency. Zorsika replacement lenses are independently designed and manufactured to the same specifications, with throw ratio, image circle, and mount matched to the original machine, offering advantages in budget and lead time. Zorsika supplies both options—choose based on your project requirements.
Q: How do I confirm this lens works with my projector?
A: Verify 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 the same mount; if unsure, photograph the unit's nameplate and send it to Zorsika technical support for confirmation—this is the safest approach.
Q: How do I choose the throw ratio?
A: Throw ratio = projection distance ÷ image width. A smaller value produces a larger image (short throw/ultra-short throw for close-range small spaces), while a larger value requires a greater installation distance. Work backward from your installation distance and screen size to determine the required throw ratio range, then match it to this model's focal length.
Q: How is the 308935 Fixed #1 guaranteed to be genuine?
A: Zorsika provides genuine products through OEM channels, complete with original packaging and traceable serial numbers; for bulk projects, channel documentation can be requested to ensure the lens is not refurbished or a used disassembled part.
Q: What should I pay attention to when replacing the lens?
A: Before removal or installation, be sure to power off the projector and wait for the cooling fan to stop; hold the lens by the barrel without touching the glass, and use a blower for dust. After installation, test focus before tightening the locking screws, and clean the mount and contacts as you go.
Q: What is the warranty period for the lens?
A: Zorsika provides a 12-month warranty on all projector lenses; for normal use and non-man-made damage (e.g., impact, water damage, unauthorized disassembly), contact after-sales service directly. The warranty period is based on the shipping document date.
