Description
Introduction of Bote Aspheric Condenser Lens
Compared with ordinary spherical lenses, aspheric condenser lenses have larger numerical aperture (NA) and lower f-number (f/#). These condensers are suitable for collimating wide-spectrum light sources, LEDs and other light sources, or for scenes that require efficient lighting.
In order to ensure the best performance, when used for point light source collimation, the beam is incident on the flatter side of the lens.
When an aspheric condenser lens is used for collimated beam focusing, the beam is incident on the surface with greater curvature.
Bote uses B270 glass to make a variety of aspheric condenser lenses. B270 glass is a high-quality glass developed by Schott. It has high surface flatness and good optical properties, and has good transmittance in the visible light band.
Compared with precision polished aspheric lenses, molded aspheric condenser lenses have the advantages of good production consistency and can be produced in large quantities.
