How Does the Measurement Process with CBS Inc. Work?

When you partner with CBS Inc. for your optical measurement needs, the process is seamless and efficient:



We work with you to discuss what measurements are suited for your project.


Ship Your Samples

Ship your samples to be measured.


Testing at opsira

Once the samples are received they are tested using advanced equipment such as the robogonio, gonio2pi.


Data Collection

After testing, we obtain raw measurement data from the machines, this data is provided as detailed Excel spreadsheets containing the analysis and a comprehensive report that includes discussions of the results.


Data Conversion

For FRED users, interested in scatter measurement, we convert the measured data into scatter models compatible with FRED optical simulation software. Similarly, for rayfiles.

This streamlined process ensures you receive precise, reliable data and insightful analysis to support your project's success.
