About This OEM Lens
BenQ LS1LT3 Long Zoom 2 Lens
The LS1LT3 Long Zoom 2 is an OEM long throw lens from BenQ. Its optical construction, lens coatings, and body tolerances are all matched to original projector standards, ensuring plug-and-play installation and stable imaging. For installation environments with limited projection distance (such as large images from short distances or ultra-short throw wall-mounted setups), choosing the correct throw ratio is more critical than selecting a general-purpose lens.
This lens has a throw ratio of 5.31:1 - 8.26:1. Throw ratio = projection distance ÷ screen width: smaller values produce larger images (suitable for close, compact spaces), while larger values require greater installation distances. Calculate the required throw ratio range based on on-site installation distance and screen dimensions, then match it to this model.
Authenticity & Purchase Guide
Zorsika provides genuine BenQ original lens LS1LT3 Long Zoom 2 through official channels, with original factory packaging and traceable serial number, suitable for bulk procurement and project supply for commercial projection, conference rooms, classrooms, and similar applications.
- Authenticity Guarantee: Official factory channels, original factory packaging with traceable serial number; bulk projects can request channel documentation to ensure no refurbished or unverified units.
- Compatibility Check: Provide the projector model number before ordering; Zorsika technical team will verify against the model compatibility list to ensure proper fit.
- Project Supply: LS1LT3 Long Zoom 2 covers 3 projector models; common projects can be scheduled in advance to shorten delivery time.
- Alternative Options: If budget is a concern, Zorsika also offers same-specification alternative lenses with key parameters matching the original; choose based on your needs.
Note: Actual imaging performance depends on projector condition and installation environment. For large quantities, it is recommended to test 1 unit first before bulk order.
Frequently Asked Questions
Q: How to choose between original and alternative lens?
A: Original lens is manufactured by BenQ with optical parameters and body tolerance calibrated to the original machine, suitable for projects with strict original manufacturer consistency requirements. Zorsika alternative lens is independently designed and manufactured to the same specifications, with throw ratio, imaging circle, and mount matching the original machine; it offers advantages in budget and delivery time. Zorsika supplies both options—choose based on your project requirements.
Q: How to confirm this lens is compatible with my machine?
A: Use the projector lens interface and panel/chip size as reference; this article lists verified compatible models. Engineering projectors of the same generation and brand often share interfaces. If unsure, take a photo of the projector nameplate and send it to Zorsika technical team for confirmation.
Q: How to choose the right Throw Ratio?
A: Throw Ratio = Projection Distance ÷ Screen Width. A smaller ratio means a larger image (short-throw/ultra-short-throw suitable for close-projection in small spaces), while a larger ratio requires 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 length range.
Q: How does LS1LT3 Long Zoom 2 ensure authenticity?
A: Zorsika provides genuine products from official factory channels with original factory packaging and traceable serial number; bulk projects can request channel documentation to confirm no refurbished or second-hand pulled parts.
Q: What should I pay attention to when replacing the lens?
A: Make sure to power off and wait for the cooling fan to stop before removal/installation; hold the lens by the barrel, not touching the glass; if dusty, gently blow with an air blower; after installation, test focus first, then tighten 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 damage, unauthorized disassembly) can be handled directly through after-sales service. Warranty period is calculated from the shipping invoice date.
