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.

Functionradiation protection, anti-fatigue
Place of origindanyang, jiangsu
Characteristics1)more clear: special coating process for perfect and comfortable visual effect.
2)more relaxed: you will feel more light and soft when you wear aspheric lenses.
3)more natural: less visual illusion and more actual visual effect is for aspheric lenses; the higher refractive index is, the better the transmittance is, the harder & thinner the lenses are.
