Beamsplitter material is inventoried in various sheet thicknesses (0.5 to 3.0mm), for specific wavelength ranges from visible to IR, and in various transmission/reflection ratios. A second-side anti-reflection coating is normally recommended and thus is offered as standard.

Beamsplitter types include:

  • Cubes
  • Plates
  • Pellicles

Reflection vs. Tranmission options:

  • 80/20
  • 50/50
  • 30/70

MidOpt is a major supplier of all the above materials/components to many well-known machine vision lighting manufacturers.

Common Applications

  • In-Line Illumination for Microscopy, and inspection of specular objects, such as semiconductor wafers.
  • Image Combining for augmented reality applications
  • Fluorescence Microscopy
  • Interferometry
