SELECTION QUESTIONS
Dome Windows FAQ
Technical answers to the questions that most often affect model selection.
When should I use a plane, wedge or Brewster window?
Choose a plane window for general beam-path protection. A wedged window separates front- and rear-surface reflections to reduce etalons and ghost images. A Brewster window is intended for a defined incidence angle and polarization state where p-polarized reflection must be minimized.
How should window material be selected?
Select the substrate from the required wavelength range, thermal load, mechanical environment and cost target. K9 optical glass serves many visible systems, UV fused silica supports ultraviolet and thermally stable use, and sapphire offers greater hardness and environmental durability.
Which window tolerances affect optical performance?
Transmitted wavefront is influenced by surface flatness, parallelism or wedge, thickness variation and material homogeneity. Surface quality and edge finish matter for scatter, handling and high-power applications. Optical flats additionally require the reference surface grade to match the inspection method.
Need a different diameter, tolerance or coating?
Send your material, wavelength, dimensions and quantity for review.
