About This OEM Lens

BenQ LS1ST3 Wide Fixed Lens

LS1ST3 Wide Fixed is an original BenQ short throw lens, with optical structure, lens coating, and body tolerances all matching original machine standards—ready for installation with stable imaging. For installation environments with limited projection distance (such as short-throw large images, ultra-short throw against wall), selecting the correct throw ratio is more critical than choosing a universal lens.

This lens has a throw ratio of 0.76:1. Throw ratio = projection distance ÷ image width: the smaller the value, the larger the image (suitable for short distance in small spaces), the larger the value, the greater the installation distance required. Back-calculate the required throw ratio range based on on-site installation distance and screen size, then match it to this model.

FAQ

Q: How to choose between original and alternative lenses?

A: Original lenses are manufactured by BenQ with optical parameters and chassis tolerances set to original specifications, suitable for projects with strict requirements for OEM consistency; Zorsika alternative lenses are independently designed and manufactured to the same specifications, with throw ratio, imaging circle, and mount matching the original machine, offering advantages in budget and delivery time. Zorsika supplies both options—choose based on your project requirements.

Q: How do I confirm this lens works with my machine?

A: Refer to the projector lens interface and panel/chip size; this article lists verified compatible models. Projectors of the same generation and brand often share interfaces. When in doubt, take a photo of the projector nameplate and send it to Zorsika technical support for confirmation.

Q: How to select the right Throw Ratio?

A: Throw Ratio = Projection Distance ÷ Screen Width. Smaller values produce larger images (short-throw/ultra-short-throw lenses suit small spaces at close range), while larger values require greater installation distance. Back-calculate the required throw ratio range based on your installation distance and screen size, then match it to the focal length of this model.

Q: How does Zorsika guarantee authenticity for LS1ST3 Wide Fixed?

A: Zorsika supplies genuine original-channel products with original packaging and verifiable serial numbers; batch projects may request channel documentation to ensure no refurbished or second-hand parts.

Q: What should I watch out for when replacing a lens?

A: Always power off and wait for the cooling fan to stop before handling; grip the lens barrel when handling, avoiding contact with the glass; after installation, test focusing before tightening the mounting screws, and clean the mount and contacts as needed.

Q: What is the lens warranty period?

A: All Zorsika projector lenses come with a 12-month warranty; normal use and non-human damage (such as impact, water damage, or unauthorized disassembly) can be handled directly through after-sales service, with the warranty period calculated from the invoice date.
