About This Original Lens

Vivitek GB805G Short Fixed Lens

The GB805G 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 the original projector's standards, ensuring plug-and-play installation and stable imaging. For installation environments with limited projection distance (e.g., projecting large images from short distances, or ultra-short throw wall-mounted setups), choosing the correct throw ratio is more critical than selecting a generic 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 close-range, 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 the original projector, making them suitable 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 can I confirm this lens works with my projector?

A: The projector's lens mount and panel/chip size are the determining factors; this article lists verified compatible models. Installation projectors of the same generation and brand often share the same mount; 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. The smaller the value, the larger the image (short throw/ultra-short throw suits close-range, small spaces); the larger the value, the greater the installation distance required. Calculate the required throw ratio range based on your installation distance and screen size, then match it to this model's focal length.

Q: How is the GB805G Short Fixed guaranteed to be genuine?

A: Zorsika supplies genuine products through OEM channels, with original packaging and serial numbers for verification; channel documentation can be requested for bulk projects to ensure they are not refurbished or used parts.

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

A: Before removal, ensure the projector is powered off and the cooling fan has stopped; 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.
