About This Original Lens

Ricoh 308937 Zoom #3 Lens

The 308937 Zoom #3 is a Long Throw lens manufactured by Ricoh as an OEM product. Its optical structure, lens coatings, and body tolerances are matched to original machine standards, ensuring plug-and-play installation and stable imaging. For installation environments with limited projection distance (e.g., short-distance large images, wall-mounted ultra-short throw), choosing the correct throw ratio is more critical than selecting a generic lens.

This lens has a throw ratio of 2.97-4.79:1. Throw ratio = projection distance ÷ image width: a smaller value means a larger image (suitable for close-range, small spaces), while a larger value requires a longer installation distance. Calculate the required throw ratio range based on your installation distance and screen size, then match it to this model.

FAQ

Q: How do I choose between an original lens and an alternative lens?

A: Original lenses are manufactured by Ricoh, with optical parameters and body tolerances calibrated to original machine standards, ideal for projects requiring strict OEM consistency; Zorsika alternative 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: Compatibility is determined by 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 nameplate and send it to Zorsika technical support for confirmation.

Q: How do I choose the throw ratio?

A: Throw ratio = projection distance ÷ image width. A smaller value means a larger image (short-throw/ultra-short-throw suitable for close-range, small spaces), while a larger value requires a longer installation distance. Calculate the required throw ratio range based on installation distance and screen size, then match it to this model's focal length range.

Q: How can I ensure the 308937 Zoom #3 is genuine?

A: Zorsika supplies genuine products through OEM channels, with original packaging and traceable serial numbers; bulk projects can request channel documentation to ensure no refurbished or used parts.

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

A: Before removal, turn off the projector and wait for the cooling fan to stop; hold the lens barrel without touching the glass, 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 ingress, unauthorized disassembly), contact after-sales service directly; the warranty period is based on the shipping invoice date.
