About This Original Lens

BenQ 5J.JDH37.031 Semi Long Zoom Lens

The 5J.JDH37.031 Semi Long Zoom is a Standard Throw lens manufactured by BenQ as an OEM product. Its optical structure, lens coatings, and body tolerances are all matched to original unit standards, ensuring plug-and-play installation with stable imaging. For installation environments with restricted projection distance (e.g., short-distance large images, ultra-short-throw wall-mounted setups), selecting the correct throw ratio is more critical than choosing a generic lens.

This lens offers a throw ratio of 1.93:1 - 2.90:1. 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 greater installation distance. Calculate the required throw ratio range based on your installation distance and screen size, then match it to this model.

Frequently Asked Questions

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

A: Original lenses are manufactured by BenQ, with optical parameters and body tolerances calibrated to original unit standards, 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 unit, offering advantages in budget and lead time. Zorsika supplies both options—choose based on your project requirements.

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

A: Verify based on the lens mount and panel/chip size; this article lists verified compatible models. Projectors of 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 select the throw ratio?

A: Throw ratio = projection distance ÷ image width. A smaller value produces a larger image (short-throw/ultra-short-throw for close-range small spaces), while a larger value requires greater installation distance. Calculate the required throw ratio range based on installation distance and screen size, then match it to this model's focal range.

Q: How can I ensure the 5J.JDH37.031 Semi Long Zoom is genuine?

A: Zorsika supplies genuine products through OEM channels, with original packaging and traceable serial numbers; channel documentation can be provided for bulk projects to ensure the unit is not refurbished or a used disassembled 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, 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 provides a 12-month warranty on all projector lenses; for normal use and non-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.
