Brand: ThorLabs | Category: Scientific & Laboratory Equipment

Large aperture aspheres in B270 crown glass, shaped for collecting and collimating light from LEDs, lamps and other extended sources. High numerical apertures gather a wide cone of light with far less spherical aberration than a spherical condenser.

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.
Positive focal length singlet lenses in Grade A N-BK7, near best form for infinite conjugate work. They are the general purpose focusing and collimating lens of an optics bench, offered from 6 mm to 75 mm diameter with a broadband antireflection coating.
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.
