Robinson Karunanithy, Suthakaran Ratnasingam, Torrey Holland, and Poopalasingam Sivakumar Bioconjugate Chem. 2023, 34, 3, 501–509 Abstract Detection of cancer before the appearance of any symptoms is crucial for successful treatment. Early detection is, however, very...

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.
