About This Original Lens

Vivitek 3797893200-SVK Long Zoom 1 Lens

The 3797893200-SVK Long Zoom 1 is an original long throw lens from Vivitek. Its optical structure, lens coatings, and body tolerances are all matched to the original machine's standards, ensuring plug-and-play installation and stable imaging. For installation environments with restricted projection distance (e.g., large images from short distances, ultra-short throw against walls), choosing the right throw ratio is more critical than opting for a generic lens.

This lens has a throw ratio of 2.00-4.00:1. Throw ratio = projection distance ÷ image width: the smaller the value, the larger the image (ideal for short distances in small spaces); the larger the value, the greater the installation distance required. Work backward from your on-site installation distance and screen size to determine the required throw ratio range, 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 machine, 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 machine, 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: The lens mount and panel/chip size on the unit are the determining factors; this article lists the verified compatible models. Projectors in the same generation and brand often share the same mount; if unsure, photograph the nameplate and send it to Zorsika technical support for confirmation—it's the safest approach.

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 short distances in small spaces); the larger the value, the greater the installation distance required. Work backward from your installation distance and screen size to determine the required throw ratio range, then match it to this model's focal length range.

Q: How can I ensure the 3797893200-SVK Long Zoom 1 is genuine?

A: Zorsika supplies genuine products through authorized channels, complete with original packaging and traceable serial numbers; for bulk projects, channel documentation can be requested to ensure it is not a refurbished unit or a used, disassembled part.

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

A: Before disassembly, be sure to power off the projector and wait for the cooling fan to stop; hold the lens by the 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.

Q: How long is the lens warranty?

A: Zorsika provides a 12-month warranty on all projector lenses; for normal use with no man-made damage (e.g., impact, water ingress, unauthorized disassembly), contact after-sales service directly; the warranty period is based on the shipping document date.
