About This Original Lens

Vivitek GC805G Ultra Short Fixed Lens

The GC805G Ultra Short Fixed is a Short Throw lens manufactured by Vivitek as an OEM product. Its optical structure, lens coatings, and body tolerances are all matched to original equipment standards, ensuring plug-and-play installation and stable imaging. For installation environments with limited projection distance (e.g., large images from short distances, wall-mounted ultra-short throw setups), selecting the correct throw ratio is more critical than choosing a universal lens.

This lens has a throw ratio of 0.77:1. Throw ratio = projection distance ÷ image width: the smaller the value, the larger the image (ideal for short distances and small spaces); the larger the value, the greater the installation distance required. Calculate the required throw ratio range based on your on-site installation distance and screen size, 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 Vivitek with optical parameters and body tolerances calibrated to original equipment 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, offering advantages in budget and lead time. Zorsika can supply 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; verified compatible models are listed in this article. Installation projectors of the same generation and brand often share the same mount; if unsure, photograph the projector nameplate and send it to Zorsika technical support for confirmation—this is the safest approach.

Q: How do I select the throw ratio?

A: Throw ratio = projection distance ÷ image width. The smaller the value, the larger the image (short throw/ultra-short throw suits close distances and small spaces); the larger the value, the greater the installation distance required. Calculate the required throw ratio range based on installation distance and screen size, then match it to this model's focal length.

Q: How can I ensure the GC805G Ultra Short Fixed is genuine?

A: Zorsika supplies genuine products through authorized channels, complete with original packaging and traceable serial numbers; channel documentation can be provided for bulk projects to ensure they are not refurbished or second-hand disassembled units.

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

A: Always power off the projector and wait for the cooling fan to stop before removal/installation; hold the lens 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.
