Femtoline Prisms

FemtoLine series laser dispersing prisms can be used inside the laser cavity operating on very low gain laser transitions, where even slight reflection losses may be intolerable. We offer laser dispersing prisms made of N-BK7, UVFS and SF11 optical materials with three different side lengths - 15, 25 and 50 mm suitable for maximum input beam diameter 6, 12 and 22 mm. Custom size laser dispersing prisms are available under request.
