Product description
Optical glass windows protect sensors, lasers, and instrument cavities while preserving wavefront quality. YC Infrared Optics fabricates flat windows in N-BK7, fused silica, and related optical glasses with controlled parallelism and surface figure.
Size capability typically ranges from 1 mm to 1000 mm depending on thickness and material. Flatness can be held to λ/20 for high-precision builds, with commercial and precision scratch-dig grades available. Broadband AR and custom coatings reduce Fresnel loss at specified bands.
Windows ship with clean-pack handling after ultrasonic cleaning, suitable for OEM assembly lines and laboratory instruments.
