Precision Wedge Windows, N-BK7 Optical Glass
Esco PN:Precision laser quality round wedge windows are ideal for applications where direct back reflections would be a problem. These elements are similar to the precision flat windows but have a deliberate wedge of 30 minutes. Optical flat wedges range from λ/4 (0.25 waves) to λ/10 (0.10 waves) flatness.
Ideal for interferometer flats, laser windows, beamsplitter substrates, or parallel plates.
