Silicon Windows for Infrared Optical Systems
ilicon Windows are widely used in infrared optical systems where a combination of infrared transmission, mechanical strength, and lightweight construction is required. As a semiconductor material with useful infrared optical properties, silicon can be manufactured into precision windows for cameras, sensors, detectors, and other optical equipment.
For infrared applications, the usable wavelength range of a silicon window is an important consideration. The material can be selected for systems where its transmission characteristics match the detector and operating wavelength.
Beyond transmission, the performance of a Silicon Optical Window also depends on thickness, surface quality, flatness, parallelism, and coating. An anti-reflection coating can be applied to reduce surface reflection and improve transmission over the required spectral range.
Typical applications include:
Infrared cameras
IR sensors and detectors
Thermal imaging systems
Industrial inspection equipment
Scientific instruments
Custom infrared optical assemblies
For OEM applications, silicon windows can be manufactured in custom shapes and dimensions according to the requirements of the optical system.
