About This Original Lens

Optoma BX-CTA19 Wide Zoom Lens

The BX-CTA19 Wide Zoom is a standard throw lens manufactured by Optoma as an OEM product. Its optical construction, lens coatings, and body tolerances are all matched to original machine standards, ensuring plug-and-play installation and stable imaging. For installation environments with restricted projection distance (e.g., short-distance large images, wall-mounted ultra-short throw), selecting the correct throw ratio is more critical than choosing a generic lens.

This lens features a throw ratio of 1.02-1.36:1. 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. Calculate the required throw ratio range based on your on-site installation distance and screen size, 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 machine standards, making them ideal for projects with strict OEM consistency requirements. Zorsika alternative lenses are independently designed and manufactured to the same specifications, with throw ratio, image circle, and mount matched to the original machine, 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: Compatibility is determined by the projector's lens mount and panel/chip size; this article lists verified compatible models. Projectors of the same generation and brand often share mounts. If unsure, photograph the unit's 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. The smaller the value, the larger the image (short-throw/ultra-short-throw suits short distances in small spaces); the larger the value, the greater the installation distance required. Calculate the required throw ratio range based on installation distance and screen size, then match it to this model's focal range.

Q: How is the BX-CTA19 Wide Zoom guaranteed to be genuine?

A: Zorsika supplies genuine products through OEM channels, with original packaging and traceable serial numbers. For bulk projects, channel documentation can be provided to ensure the units are not refurbished or used parts.

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

A: Before removal or installation, ensure the projector is powered off and the cooling fan has stopped. Hold the lens by the barrel without touching the glass; use a blower to gently remove dust. After installation, test focus before tightening the locking screws, and clean the mount and contacts as needed.

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 (e.g., impact, water damage, unauthorized disassembly), contact after-sales service directly. The warranty period is based on the shipping invoice date.
