Glass and Acrylic Laser Safety Windows: Which One is Right for You?

When it comes to selecting laser safety windows, the choice between glass and acrylic can be challenging. Both materials have their pros and cons, and your specific needs will determine which one to choose. In this article, we’ll explore the differences between the two materials and help you decide which is the best fit for your application.

Laser Safety Window Material: Glass Vs Acrylic

Laser safety windows are essential components for viewing and operating laser systems safely. They are used in a variety of settings, including enclosures, walls, glove boxes, and viewing windows of various sizes.

There are several factors to consider when determining which window material is optimal for your application, including the size of your viewing port, the protection needed, and the possibility of a stray beam striking the laser window for an extended period before being switched off, for example.

With that in mind, here are some factors to consider when choosing between glass and acrylic laser safety windows:

Size: Glass laser safety windows are typically smaller, with common sizes of 6.5 x 6.5 inches. However, custom sizes and shapes are available. On the other hand, acrylic windows are available in larger sizes, up to 2 x 3 feet, and are easier to obtain in custom shapes and sizes.

Protection: Glass laser safety windows offer the highest visible light transmission and optical density protection, making them the safest and easiest to view through. Acrylic windows are often darker, with lower visible light transmission than glass windows, but still provide ample protection from lasers.

Durability: Glass windows can withstand direct contact from a laser beam for much longer than acrylic windows can. Glass has a higher melting point, so it takes longer for the laser to melt and penetrate the material compared to acrylic.

Cost: Acrylic laser safety windows are generally less expensive than glass windows, making them the better choice if you’re on a budget.

Ease of installation: Acrylic windows are generally easier to install than glass windows.
