TECHSPEC® Uncoated Laser Window Substrates are laser quality window substrates designed to be used in demanding laser applications. These laser window substrates are available, manufactured from fused silica for high power laser applications that require excellent thermal stability or from N-BK7 for more cost sensitive laser applications. Both the fused silica and N-BK7 laser window substrates feature precision grade λ/10 surface flatness and 10-5 surface quality, ensuring minimal disturbance to transmitted beams. TECHSPEC® Uncoated Laser Window Substrates are available in standard imperial sizes from 12.7 to 50.8mm in diameter for the convenience of drop-in replacement into existing laser systems. Custom dimensional and coating options are available, please contact us for custom inquiries.
