6.5mm Diameter x 6mm FL, MgF 2 Coated, PCX Condenser Lens

Product Details Molded Illumination Lenses Aspheric or Spherical Designs High Numerical Apertures 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. The Plano-Convex (PCX) Condenser Lenses are molded on both surfaces, offering excellent value.
