About This Original Lens

Optoma BX-CTA15 Short Zoom Lens

The BX-CTA15 Short Zoom is a standard throw lens manufactured by Optoma as an OEM product. Its optical construction, lens coatings, and body tolerances are matched to original projector standards, ensuring plug-and-play installation and stable imaging. For installations with limited projection distance (e.g., short-distance large images, ultra-short throw near walls), selecting the correct throw ratio is more critical than choosing a generic lens.

This lens has a throw ratio of 0.75-0.95:1. Throw ratio = projection distance ÷ image width: a smaller value produces a larger image (ideal for short distances in small spaces), while a larger value requires a longer installation distance. Calculate the required throw ratio range based on your installation distance and screen size, 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 Optoma, with optical parameters and body tolerances calibrated to original projector standards, making them 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, 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: 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 the same mount; 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. A smaller value produces a larger image (short throw/ultra-short throw suits close-range small spaces), while a larger value requires a longer 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 BX-CTA15 Short Zoom is genuine?

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

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

A: Before removal/installation, always power off the projector and wait for the cooling fan to stop; hold the lens barrel without touching the glass, and use a blower for 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 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.
