About This Original Lens

Vivitek GB949G Long Zoom Lens

The GB949G Long Zoom is a long-throw lens manufactured by Vivitek, with optical construction, lens coating, and chassis tolerances all matched to original specifications—ready for installation with stable imaging performance. For installations with limited projection distance (such as short-throw large images or wall-mounted ultra-short-throw setups), choosing the correct throw ratio is more critical than selecting a universal lens.

This lens has a throw ratio of 2.22-4.43:1. Throw Ratio = Projection Distance ÷ Screen Width: a smaller value produces a larger image (suitable for short-distance small spaces), while a larger value requires a greater installation distance. Calculate the required throw ratio range based on your actual installation distance and screen size, then match it to this model.

Frequently Asked Questions

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

A: Original lenses are manufactured by Vivitek, with optical parameters and chassis tolerances calibrated to original specifications—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 unit, offering advantages in budget and delivery time. Zorsika supplies both options—choose based on your project requirements.

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

A: Use the chassis lens interface and panel/chip size as your reference; this article lists verified compatible models. Projectors from the same generation and brand often share interfaces. If unsure, photograph the chassis nameplate and send it to Zorsika technical support for confirmation.

Q: How do I choose the right throw ratio?

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

Q: How does Zorsika guarantee the GB949G Long Zoom is genuine?

A: Zorsika supplies authentic products through original factory channels, complete with original packaging and traceable serial numbers. Bulk projects may request channel documentation to verify no refurbished or secondhand disassembled parts.

Q: What should I watch out for when replacing the lens?

A: Always power off and wait for the cooling fan to stop before disassembling or installing. Handle the lens by the barrel—do not touch the glass. Use a air blower to gently remove any dust. After installation, test focus before tightening the mounting screws, and clean the mount and contacts as needed.
