WHY and WHEN replacing Laser Debris Shields - Fiber Laser Protective Windows?

Posted by Ana Walters on

If you have a High-Power Fiber Laser,  one good question should be:

- WHY and WHEN Replacing Laser Debris Shields?

Installed between a laser’s optical component and the work area, protective windows or laser debris shields protect the optics from dust, vapors, fragments, slag, and so on. The quality of the protective window is very important to avoid down-time, and also to increase the lifetime of your optics components,  specifically the lens and/or normal operation of the laser, keeping the quality and performance of the laser system.

By the nature of their use, laser debris shields are a consumable product. Covering the optical element of a laser, cover slides collect dust and block debris that would otherwise come into direct contact with the laser. Also, debris shields allow operators to better see and operate the lasers. Over time, these shields will collect a layer of dust and microscopic nicks and scratches. Failure to replace laser debris shields in a timely manner can lead to altered or diminished laser performance. Protective Windows are designed to prevent down-time and to protect your company investment and equipment.

We recommend replacing protective windows frequently, however it really depends on how many hours your machine is working. Some customers replace their protective windows every single day, some others replace them every 80 hours, or every Friday. It actually depends on the amount of runtime and your best judgment. It’s like taking a shower… maybe you can go without for a few days, but the consequences are negative. The best maintenance is the preventative one! Do not wait for it to break, and then fixing it. The down-time can be very distressing and expensive.

American Photonics (APC) manufactures and sells Fiber Laser Protective Windows (debris shields) in many standard diameters, or based on customer requests.

We do have immediate delivery of protective windows that work with most of today’s industrial laser processing systems.

To ensure that they not only protect the laser optical component, but also allows the laser to function as designed, debris shields from American Photonics (APC) are manufactured with customized ultra-low reflectivity and excellent quality of laser grade raw material.

Here is a list of Protective Windows that American Photonics has available for immediate delivery. Usually, fiber laser protective windows are sold on the website in packs of 5 units. Distributor or large quantity pricing is available with a discount. Please contact American Photonics sales team:
