UV Fused Silica Aspheric Lens GLA21-050-040-UV
Aspheric lenses correct spherical aberration in barcode scanning, laser-diode collimation and OEM development/integration. Their single-element design minimizes lens count in multi-lens assemblies. * All lenses are designed for 405nm; other bands require consideration of refractive-index-related performance changes. Contact us for details. ** WD is the theoretical distance from the lens plane to the focus. *** Refraction causes the entrance and exit faces to have different clear apertures.
