What is a D-LENS?

Oct 13, 2021 | Glossary of Spectroscopy Terms, Spectroscopy

This lens is placed over the detector to focus the vertical bands of order sorted light to the detector. StellarNet can install a D-Lens on top of any detector in one of our crossed Czerny Turner optical benches. Holographic Concave Grating designs like our...

What is efficiency?

Oct 13, 2021 | Glossary of Spectroscopy Terms, Spectroscopy

Efficiency relates to the performance of the various components in an optical system. The goal is to make spectrometers with the highest efficiency possible. Light will absorb into optical components before it reaches the detector; the detector will also have an...

What is Colorimetry?

Aug 20, 2021 | Glossary of Spectroscopy Terms, Spectroscopy

Colorimetry is the science and technology used to quantify and describe physically the human color perception.

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.
