What is the Color Quality Scale (CQS)?

Aug 20, 2021 | Glossary of Spectroscopy Terms, Spectroscopy

Color Quality Scale or CQS is a color rendering index scale developed by our friends at NIST. The goal of CQS is to offer a quantitative measure of the ability of a light source to reproduce the colors of illuminated objects.

What is a color equalization filter?

Aug 13, 2021 | Glossary of Spectroscopy Terms, Light Source, Spectroscopy

The SL1-Filter comes with a color equalization filter. Halogen lamps naturally emit a black body curve with weak blue emissions and strong green, yellow, red, and NIR. The Color Equalization Filter knocks down the emissions in the stronger wavelengths and allows the...

What is a collimating lens?

Aug 13, 2021 | Glossary of Spectroscopy Terms, Spectroscopy

A collimating lens is an accessory that fits at the end of a fiber optic cable and takes a beam of light and focuses it into the fiber. When the light is emitting from the fiber, the light is focused to a narrow 3° column.
