We can process all kinds aspheric condenser lenses, parabolic mirror and off-axis parabolic mirror. Aspheric condenser lenses efficiently correct for spherical aberrations and coma. For this reason, one Aspheric condenser can replace a multiple spherical element design. This replacement reduces the number of Back reflections and ultimately yields higher transmission.

Condenser lenses are molded lenses designed for illumination applications. Featuring large apertures and short focal lengths, condenser lenses are commonly used in emitter-detector applications, projection applications, or condensing illumination applications such as koehler illumination. The aspheric condenser lenses are molded on the aspheric surface and ground and polished on the opposite face, offering superior performance.
