Absorbance and transmittance are two ways to express how much light a sample absorbs, linked by a simple logarithmic relationship.

Detector choice determines spectral range and measurement speed; silicon photodiodes, CMOS arrays, and InGaAs devices each serve distinct analytical needs.

Wavelength is the distance between successive peaks of a light wave. It determines a photon’s energy and underpins every spectroscopic measurement.
