Near Infrared Polariscope

The LSM-9001NIR fully automatic polarimeter for low phase difference products such as semiconductor wafers. This remarkable new technology allows for stress inspection of previously impossible materials.

STRESS – WRITE ABOUT THAT HERE

With the NIR instrument you can now look for stress in the following materials

  • Silicon Wafers
  • Silicon [Si]
  • Silicon Carbide[SiC]
  • Gallium Nitride [GaN]
  • Glass wafer
  • Transparent and colored resin products
  • Crystallized Quartz / Quartz / Optical crystals
The Si disc is opaque to white light (left) but is clear to the NIR scan (right).

The Luceo LSM-9101NIR is an automated polariscope that provides precise retardation measurements with image resolutions as small as 10 microns per pixel. Polarized source light is passed through a transmitting optical material and then passed through an analyzing polarizer and onto a detector. Rotation of the analyzing polarizer through a range of angles allows for calculation of the retardation at different areas of the optical component being measured.
