General Optics
AR-Coated Windows
Transmit infrared light and laser beams with minimal loss and wavefront distortion using these precision, anti-reflection coated, plane parallel windows.
Windows are used frequently in optical systems, often for environmental isolation - such as to seal vacuum or high-pressure cells. The high refractive index of infrared materials makes anti-reflection coatings a necessity to reduce reflective losses.
