ATR Silicon Crystals & Prisms

Attenuated Total Reflectance - ATR crystals silicon

Standards dimensions:

  • 52 x 20 x 2mm 45° ATR Crystal
  • 80 x 10 x 4mm 45° ATR Crystal

Sil’tronix manufactures on demand silicon ATR Crystals for FTIR-ATR spectroscopy and neutron Sil-tronix-infrared-prism.jpgexperiments.

Standards tolerances:

  • Thickness: +/-0.2 mm
  • Angle: +/-0.01°
  • Surface quality of polished surfaces, scr/dig 80/50
  • Surface quality of ground surface, Ra 2.5
  • Surface accuracy, mm +/-0.01 deviation from ideal plane

Silicon Prisms

We offer THz prisms of the following configurations:

  • Attenuated Total Reflectance - ATR prisms. These special prisms allow investigating materials that are difficult to analyze in transmission.
  • Conventional prisms used in spectroscopic applications

    Note: All our prisms are manufactured with High Resistivity Float Zone Silicon (HRFZ-Si)

Conventional Prisms
All our THz prisms are manufactured upon request.
Examples of our know how: Sil-tronix-infrared-prism.jpg

  • Prism with Brewster Angle: 25 x 14 x 18mm (73.98°)
  • Pair of prisms made of Si for pulse compression: 32.2° Apex angle, 100 mm longer side, 30 mm height
  • Equilateral prism: 12.7 x 12.7 x 12.7 mm
  • Equilateral prism: 32 mm x 32 mm x 32 mm
