Holmarc provides high precision optical windows with BK7 and UV fused silica substrates. Our optical windows are available in circular, square, or rectangular shapes with or without Anti-reflection coatings. Windows with custom sizes and shapes can be supplied to order. Anti-reflection coatings for custom wavelength regions are also available.
Optical Windows allow light beam to pass from one medium to another without changing the wavelength distribution or the transmitted wave front of the beam.
These optical windows are precision manufactured using BK7 or equivalent and Fused silica. We can also work with substrates furnished by the customer.
