Product Description
The Laser Flat Optical Window is designed to deliver outstanding durability and optical clarity for demanding laser applications. Constructed from H-K9L optical glass, it undergoes precision annealing to achieve exceptional homogeneity and minimal birefringence.
With a surface flatness of λ/10 at 633 nm and parallelism under 5 arcseconds, it minimizes optical distortion and power loss. The 20-10 surface quality ensures a clean, scratch-free surface that withstands high laser energy exposure. Ideal for laser cutting heads, beam delivery systems, and optical inspection instruments, this window offers reliable protection without compromising transmission efficiency.
