About This Original Lens

Vivitek 3797859900-SVK Short Zoom 2 Lens

The 3797859900-SVK Short Zoom 2 is an OEM Standard Throw lens manufactured by Vivitek. Its optical structure, lens coatings, and body tolerances are all matched to the original projector standards, ensuring plug-and-play installation with stable imaging. For installation environments with restricted projection distance (e.g., large images from short distances, wall-mounted ultra-short throw setups), choosing the right throw ratio is more critical than opting for a generic lens.

This lens features a throw ratio of 1.20-1.56:1. Throw ratio = projection distance ÷ image width: a smaller value produces a larger image (ideal for short distances in small spaces), while a larger value requires a greater installation distance. Work backward from your 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 projector, making them ideal for projects with strict OEM consistency requirements. Zorsika replacement lenses are independently designed and manufactured to the same specifications, with throw ratio, image circle, and mount matched to the original unit, 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: Refer to the projector's lens mount and panel/chip size; this article lists verified compatible models. Projectors in the same generation and brand often share the same mount. If unsure, photograph the unit's nameplate and send it to Zorsika technical support for confirmation—this 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 suits close-range small spaces), while a larger value requires a greater installation distance. Work backward from your installation distance and screen size to determine the required throw ratio range, then match it to this model's focal range.

Q: How is the 3797859900-SVK Short Zoom 2 guaranteed to be genuine?

A: Zorsika supplies genuine products through OEM channels, with OEM packaging and traceable serial numbers; channel documentation can be provided for bulk projects, ensuring the unit is not refurbished or a used pulled part.

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.

Q: What is the warranty period for the lens?

A: Zorsika offers 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.
