About This Genuine Lens

Christie 121-119102-XX Zoom Lens

The 121-119102-XX Zoom is a Christie genuine standard throw lens, with optical construction, lens coating, and housing tolerances all matching original specifications—ready for installation with stable imaging performance. For installation environments with limited projection distance (such as large images at short range, or ultra-short throw against the wall), selecting the correct throw ratio is more critical than choosing a universal lens.

This lens has a throw ratio of 1.18-1.75:1. Throw ratio = projection distance ÷ screen width: a smaller value produces a larger image (suitable for short distances in small spaces), while a larger value requires greater installation distance. Back-calculate the required throw ratio range based on your site installation distance and screen size, then match it to this model.

FAQ

Q: How to choose between original and alternative lenses?

A: Original lenses are manufactured by Christie with optical parameters and machine tolerances calibrated to original specifications, suitable for projects with strict requirements for OEM consistency; Zorsika alternative lenses are independently designed and manufactured to the same specifications, with throw ratio, imaging circle and mount matching the original machine, offering advantages in budget and delivery time. Zorsika supplies both options—select based on your project requirements.

Q: How to confirm this lens works with my machine?

A: The standard is the projector's lens interface and panel/chip size; this article lists verified compatible models. Same-generation same-brand engineering projectors often share interfaces. If unsure, take a photo of the machine nameplate and send it to Zorsika technical team for confirmation.

Q: How to choose the Throw Ratio?

A: Throw Ratio = Projection Distance ÷ Screen Width. Smaller values produce larger images (short-throw/ultra-short-throw suitable for close-proximity small spaces), while larger values require greater installation distance. Calculate the required throw ratio range based on installation distance and screen size, then match the focal length of this model.

Q: How does 121-119102-XX Zoom ensure authenticity?

A: Zorsika provides genuine products through original factory channels, with original packaging and verifiable serial numbers; batch projects can request channel certificates to ensure no refurbished or second-hand demounted parts.

Q: What should I note when replacing the lens?

A: Always power off and wait for the cooling fan to stop completely before disassembly and assembly; hold the lens barrel without touching the lens glass, gently blow off dust with an air bulb; after installation, test focus first before tightening the mounting screws, and clean the mount and contacts.

Q: What is the warranty period for the lens?

A: All Zorsika projector lenses come with 12-month warranty; normal use and non-human damage (such as impacts, water ingress, unauthorized disassembly) can be handled through after-sales service. Warranty period is based on the shipment invoice date.
