Optical Flat Stands

optical flat stands

Large optical flats (Eg 250mm diameter and above) are heavy. If they are placed directly onto a thin component such as mechanical seals, they can cause distortion of the component and incorrect light band readings.

Kemet offer monochromatic lights incorporating bench stands to hold large optical flats. The optical flat is held in the stand. The component is then placed on top of the optical flat. The sodium lamp displays the light bands between the component and the optical flat. The mirror on the underside of the stand allows the inspector to view the light band readings. The Bench top monolight is suitable for measuring non solid objects such as rings.


  • No incorrect light band readings due to component distortion
  • Protection of optical flat
  • Able to accurately measure a variety of component sizes
  • No handling of optical flat required
