About This Original Lens
Christie 118-100115-03 ILS1 Zoom Lens
The 118-100115-03 ILS1 Zoom is a Long Throw lens manufactured by Christie. Its optical structure, lens coatings, and body tolerances are all matched to the original projector standards, ensuring plug-and-play installation and stable imaging. For installation environments with restricted projection distances (such as short-distance large-screen projection or ultra-short-throw wall-mounted setups), choosing the correct throw ratio is more critical than opting for a generic lens.
This lens features a throw ratio of 4.10-6.90:1. Throw ratio = projection distance ÷ image width: a smaller value produces a larger image (ideal for close-range, compact spaces), while a larger value requires a greater 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 Christie, with optical parameters and body tolerances calibrated to the original projector, making them ideal for projects with strict OEM consistency requirements; Zorsika replacement lenses are independently designed and manufactured to the same specifications, with throw ratio, image circle, and mount aligned 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 projector's lens mount and panel/chip size; this article lists verified compatible models. Projectors from 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 choose 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, compact spaces), while a larger value requires a 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 118-100115-03 ILS1 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 no refurbished or second-hand units.
Q: What should I pay attention to when replacing the lens?
A: Power off the projector and wait for the cooling fan to stop before removal; 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 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-human damage (such as impact, water ingress, or unauthorized disassembly), contact after-sales service directly, with the warranty period based on the shipping invoice date.
