About This Original Lens

Vivitek D98-2040 Long Zoom Lens

The D98-2040 Long Zoom is an original long throw lens manufactured by Vivitek. Its optical structure, lens coatings, and body tolerances are all matched to original projector standards, ensuring plug-and-play installation and stable imaging. For installation environments with restricted projection distances (such as projecting large images from short distances or ultra-short-throw wall-mounted setups), choosing the correct 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 (suitable 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 original projector standards, 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 do I confirm this lens works with my projector?

A: Base your decision on the lens mount and panel/chip size of the projector; this article lists verified compatible models. Projectors from 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 small spaces with short distances); 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 D98-2040 Long Zoom is genuine?

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

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

A: Before disassembly, make sure the projector is powered off and the cooling fan has stopped; hold the lens by the barrel and avoid touching the glass, use a blower for dust; after installation, focus-test first 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 and non-man-made damage (such as impacts, water ingress, or unauthorized disassembly), contact after-sales service directly; the warranty period is based on the shipping document date.
