About This Original Lens
Christie 118-130105-03 ILS1 Zoom Lens
The 118-130105-03 ILS1 Zoom is a standard throw lens manufactured by Christie as original equipment. Its optical structure, 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 against walls), choosing the correct throw ratio is more critical than selecting a generic lens.
This lens has a throw ratio of 0.80-1.16:1. 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 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 original projector standards, making them suitable 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 matched to the original, offering advantages in budget and lead time. Zorsika supplies both options, so choose based on your project requirements.
Q: How do I confirm this lens works with my projector?
A: Verify based on the lens mount and panel/chip size on your projector; this article lists verified compatible models. Professional projectors of the same generation and brand often share the same mount, so if unsure, take a photo of the 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 small 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's focal range.
Q: How can I be sure the 118-130105-03 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 the lens is not refurbished or a used disassembled unit.
Q: What should I pay attention to when replacing the lens?
A: Always power off the projector and wait for the cooling fan to stop before removing or installing the lens; hold the lens 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 offers 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.
