About This Original Lens

Vivitek 3797858100-SB Long Zoom 2 Lens

The 3797858100-SB Long Zoom 2 is an original Long Throw lens manufactured by Vivitek. 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 restricted projection distances (e.g., large images from short distances, ultra-short throw against walls), choosing the correct throw ratio is more critical than selecting a universal lens.

This lens has a throw ratio of 4.00-7.00:1. Throw ratio = projection distance ÷ image width: a smaller value produces a larger image (suitable for short distances in small 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.

FAQ

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

A: Original lenses are manufactured by Vivitek, with optical parameters and body tolerances calibrated to the original equipment, making them suitable for projects with strict requirements for 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, 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 will work 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. Projectors of the same generation and brand often share the same mount. If you are unsure, sending a photo of the nameplate to Zorsika technical support for confirmation 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 for close distances in small spaces), while a larger value requires a 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 can I be sure the 3797858100-SB Long Zoom 2 is genuine?

A: Zorsika supplies genuine products through official OEM channels, with original packaging and traceable serial numbers. For bulk projects, channel documentation can be requested to ensure the product is not refurbished or a used pulled part.

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

A: Before removal or installation, be sure to power off the projector and wait for the cooling fan to stop. Hold the lens by the barrel and avoid touching the glass; use a blower for dust. After installation, test focus before tightening the locking screws, and clean the mount and contacts as a routine step.

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), please contact after-sales service directly. The warranty period is based on the shipping document date.
