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.
- 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 superscript-4 degrees
- Scatter light data and models for different optics simulation tools
