025 PX 025 High-Index Planoconvex Laser Lens
Description
Lenses in high-index glass (n = 1.785) have only 55% of the spherical aberration of equivalent BK7 lenses, and can be very efficiently AR coated with a single-layer coating. Beam expanders etc. can therefore be made with near diffraction-limited performance and very high transmittance and suitable for high powers, having no cemented interfaces.
