Meniscus Lens

الوصف

Meniscus lenses have one concave and one convex surface. For this lens type, the two curvatures are chosen to minimize the spherical aberration at one laser wavelength, hence meniscus lenses are used to control a laser beam of the appropriate wavelengths. We offer meniscus lenses with and without AR coating.
