• Very Economical
• AR Coated 350 - 700 nm
• Offers Higher NA and Less Spherical Aberration than Spherical Lenses

This Aspheric Condenser Lens is ideal for high-efficiency illumination applications. Compared to spherical lenses, this lens introduces fewer aberrations, offers larger apertures, and provides lower f/d ratios. This aspheric condenser lens is designed for collimating light from a lamp, LED, or similar light source; for best performance in this application, the plano side of the lens should face the source.
