Choosing the right laser safety window depends on several factors, including the laser’s power, wavelength, exposure time, and the type of laser application. It’s important to consider your specific application because each material, such as acrylic and glass windows and sheets, has its own strengths and weaknesses. 

Considering that, here’s a brief overview of the common uses, strengths, and weaknesses of acrylic and glass windows and sheets:

• Acrylic laser windows are typically used when larger sizes and shapes are needed.
• Acrylic offers good scratch resistance and superior optical clarity.
• Acrylic is easily cut to special shapes and sizes, even particularly large ones.
• When custom coverage ranges are needed and cannot be accomplished through a combination of glass filters, acrylic is typically the material used to develop the new filter.
