Link Metal CNC Collimating Lens for Fiber Laser Welding & Cutting Machines

Collimating Lens for Fiber Laser Welding & Cutting Machines 1064nm

Professional high-precision optical collimating lenses specially designed for mainstream fiber laser welding machines, cutting machines and handheld laser welding torches. As a core optical component of the laser head, the collimating lens converts the diverging laser beam from the optical fiber into a perfectly parallel beam, ensuring stable laser transmission and optimal processing results.

Made from premium fused silica material with advanced anti-reflection coating, these collimating lenses provide stable performance, excellent anti-spatter properties and long service life. They are ideal replacement accessories for daily maintenance of all fiber laser equipment.

Frequently Asked Questions

Q: What does a collimating lens do in a fiber laser system?
A: A collimating lens converts the diverging laser beam emitted from the end of the optical fiber into a perfectly parallel beam. This is essential for maintaining consistent beam quality over distance and ensuring optimal performance of the subsequent focusing lens.

Q: How do I choose the correct collimating lens for my welding torch?
A: You need to match the exact diameter, focal length, center thickness and edge thickness of your original lens. The easiest way is to check the part number on your old lens or refer to your laser head manual. You can also contact our sales team with your torch model for assistance.

Q: How often should I replace the collimating lens?
A: Under normal operating conditions, a collimating lens should last 3-6 months. However, it should be replaced immediately if you notice any film burning, scratches, spatter damage or if welding/cutting quality deteriorates. Regular cleaning and proper maintenance can extend its service life.

Q: Can I clean the collimating lens?
A: Yes, you can clean slightly contaminated lenses using proper techniques. Always wear clean gloves and use a blower ball first to remove loose dust. Then gently wipe with a lint-free microfiber cloth and lens cleaning fluid. Never use regular paper towels or tissues as they will scratch the coating.

Q: Are these collimating lenses compatible with my brand of laser equipment?
A: Our collimating lenses are compatible with most mainstream fiber laser brands including Qilin, Hanwei, WSX, Raytools, Precitec, Reci, Max and more. If you are unsure about compatibility, please contact our sales team with your laser head model.
