scattered light measurement

Light always scatters off of surfaces

Light always scatters off of surfaces. Therefore, it is absolutely necessary to accurately measure the scatter behavior of materials in order to achieve high-fidelity simulations that will lead to high-quality optical products.

opsira’s Scatterometer is goniometer based with the ability to measure 2D or 3D bi-directional scattering distribution function (BSDF) data, the metric of scattered light.  The measured BSDF-data are available in a number of different formats and can be imported by all current optical simulation program.

Possible measurements:

  • Measurement of the scattered light distribution in reflection and transmission (BSDF, BRDF)
  • Measurement dynamics up to 8 magnitudes for the measurement of the scatter light of extremely low level
  • Measuring angle resolution up to 10-4 degrees
  • Scatter light data and models for different optics simulation tools
