Brand: ThorLabs | Category: Scientific & Laboratory Equipment

Cylindrical lenses that focus or magnify in one axis only. They are used to circularise the elliptical output of a laser diode, form a line focus and give anamorphic beam shaping on an optical bench.

Metallic mirrors with a silver coating and a silicon dioxide overcoat, giving the highest visible and near infrared reflectance of any Thorlabs metallic mirror. Round, square and rectangular formats are stocked, and the broad response suits femtosecond pulses.
Magnetorheologically polished aspheric lenses in N-BK7 or S-LAH64 that reach diffraction limited performance. They focus or collimate a laser beam in a single element and are used where a doublet would add too much wavefront error.
Gold coated mirrors with a protective dielectric overcoat, intended for infrared work where reflectance must stay high well beyond 2 micrometres. Reflectance is relatively insensitive to angle of incidence, as with other metallic coatings.
