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.

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

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.

ZnSe offers high uniformity and homogeneity for imaging uses and low absorption and scatter for high-power laser applications; its visible light transmission simplifies optical system alignment. ZnSe is also non-hygroscopic and chemically stable.

Build high-performance common aperture systems that operate across wavelengths ranging from 400 nm to 12 µm with minimal scatter and excellent mechanical properties.

Learn how we are enabling the next generation of high-speed optical transmission systems, networks, and datacenter solutions.

Choose ZnS for domes, windows, lenses and other transmissive optics whenever mechanical strength, hardness, or operation in harsh environments is required.

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.

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.

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.
