Windows

Available in different sizes
BK7 & Fused silica substrate

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. Ideally, optical windows do not scatter light out of the beam. Holmarc offers windows in two different materials; N-BK7 & Fused Silica. Holmarc's windows are available in uncoated, single layer MgF2 coated, and broadband AR coated options.
