About This Original Lens

Optoma BX-CTA17 Short Zoom Lens

The BX-CTA17 Short Zoom is a short-throw lens manufactured by Optoma as original equipment. Its optical structure, lens coatings, and body tolerances are matched to original unit standards, ensuring plug-and-play installation and stable imaging. For installations with limited projection distance (e.g., large images from short distances, ultra-short-throw wall-mounted setups), choosing the correct throw ratio is more critical than selecting a generic lens.

This lens has a throw ratio of 0.65-0.75:1. 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 an alternative lens?

A: Original lenses are manufactured by Optoma, with optical parameters and body tolerances calibrated to original unit standards, making them ideal for projects with strict requirements for original consistency; Zorsika alternative 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 can I confirm this lens works with my projector?

A: Refer to the unit's lens mount and panel/chip size as the authority; 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 unit's 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 at close range); 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 BX-CTA17 Short Zoom is genuine?

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

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

A: Before disassembly, make 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 first 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 and non-manual damage (e.g., impact, water ingress, unauthorized disassembly), contact after-sales service directly—the warranty period is based on the shipping document date.
