Product Details

  • Combine a Condenser and Diffuser into One Element
  • Fine, Medium, and Rough Diffuser Surface Textures
  • Provide Diffuse, Homogenous Illumination
  • Condenser Lenses and Diffusers Also Available

Molded Diffuse Aspheric Condenser Lenses combine a condenser lens and a diffuser into one optical element to simplify illumination systems. These lenses collimate light from LEDs and other light sources to provide homogenous illumination with greater efficiency than using a condenser lens with a ground glass diffuser. Lenses are available with three molded diffuser surface textures (fine, medium, and rough) with coarser textures providing a higher degree of diffusion but lower transmission. Molded Diffuse Aspheric Condenser Lenses feature durable glass substrates, enabling their use with low to high power LEDs, and are ideal for space constrained systems requiring diffuse, homogenous illumination.

Technical Information

MOLDED DIFFUSE ASPHERIC CONDENSER LENSES
Regular Condenser Lens Condenser Lens with Smooth Diffuser Conenser Lens with Medium Diffuser Condenser Lens with Rough Diffuser
Light collimated from an LED using a regular condenser lens and condenser lenses with a diffuser surface. As the texture of the diffuser surface becomes rougher, the level of diffusion increases.
