About This Original Lens

Vivitek GB942G Short Zoom Lens

The GB942G Short Zoom is a standard throw lens manufactured by Vivitek 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 restricted projection distances (e.g., short-distance large images, ultra-short throw against a wall), choosing the right throw ratio is more critical than opting for a generic lens.

This lens offers a throw ratio of 1.33-1.79:1. Throw ratio = projection distance ÷ image width: a smaller value produces a larger image (ideal for short distances in compact spaces), while a larger value requires a greater installation distance. Calculate the required throw ratio range based on your on-site installation distance and screen size, then match it to this model.

Frequently Asked Questions

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

A: Original lenses are manufactured by Vivitek with optical parameters and body tolerances calibrated to original machine standards, ideal for projects with strict OEM consistency requirements; 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 can supply both options; choose based on your project requirements.

Q: How can I confirm this lens works with my projector?

A: Compatibility is determined by the lens mount on the projector and the panel/chip size; this article lists verified compatible models. Projectors of the same generation and brand often share mounts; if uncertain, photograph the nameplate on the unit 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 is ideal for close-range compact spaces), while a larger value requires a greater installation distance. Calculate the required throw ratio range based on installation distance and screen size, then match it to this model's focal range.

Q: How is the GB942G Short Zoom guaranteed to be genuine?

A: Zorsika supplies genuine products through OEM channels, with original packaging and traceable serial numbers; bulk projects can request channel documentation 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 disassembly, ensure the projector is powered off and the cooling fan has stopped; hold the lens barrel without touching the glass, use a blower for dust; after installation, perform a focus test before tightening the locking screws, and clean the mount and contacts as you go.
