A typical optical window is typically an optical element with no optical power and consists of two plane-parallel surfaces. The optical window is used for isolating internal components from the external environment, while allowing light within a specified wavelength range to pass through. The optical window does not focus or diverge light.
The common materials for manufacturing optical windows are BK7 optical glass and UV fused silica. Transmittance and beam quality can be affected by material, thickness, surface flatness, parallelism, transmitted wavefront distortion, and anti-reflection (AR) coating.
Applications
For the optical windows’ ability to allow light to pass through while protecting internal elements from dust, moisture, airflow and maintaining a vacuum system, the optical windows are commonly used for laser output protection, industrial laser equipment, machine vision, industrial cameras, spectrometers, sensors, photodetectors, medical systems, and scientific instruments.
