OPTICAL WINDOWS AND FLATS
G&H deliver high performance optical windows and flats across a wide range of applications. From small precsion optical flats for interferometry applications, to large windows installed in military vehicles, our components are custom designed to deliver performance and value.
Optical windows are a critical component in a variety of applications which require minimal optical impact with maximum mechanical separation between two environments.
Ideally, the window has minimal impact upon the beam transmission properties: does not reflect, absorb, or scatter the beam; does not distort or impact the wavefront; does not bend or deviate the beam path.
The mechanical separation may require thermal, chemical, or environmental tolerance. Careful material selection and coating design is often required to achieve all of the mechanical separation as well as the optical needs.
OPTICAL WINDOWS FOR INDUSTRIAL APPLICATIONS
Optical windows are utilized in lasers, testing chambers, and other systems where the environment on one side may be pressurized, filled with a specific gas, or otherwise need to be chemically separated from the other. The window needs to transmit the photon energy with minimal disruption (highest transmission, lowest absorption and scattering, and minimal polarization or optical path distortion).
The highest quality optical windows from G&H demonstrate very high parallelism, supremely low surface roughness, low transmitted and reflected wavefront errors, and are optical transparent at the operational wavelength range.
Window material is chosen based on environmental factors such as acidity of atmosphere, strong vacuums, high pressures, or high temperatures and the operational wavelength range.
WINDOWS FOR DEFENSE APPLICATIONS
Defense-grade windows from G&H are significantly larger and may be coated with diamond-like coatings to withstand abrasive environments in the desert.
Window thickness is determined by environmental factors: pressure differentials, thermal conditions, and mounting mechanics.
