Spectrometers are analytical instruments which disperse an emission (such as particles or radiation) according to some property of the emission (such as mass or energy) in order to measure the amount of the dispersion. This product area includes visible, infrared (IR), ultraviolet (UV), atomic absorption (AA), optical emission (OE), Raman, X-ray fluorescence (XRF) and mass spectrometers. Specific search forms are also available.

Color and appearance instruments are used to measure the properties of paints and coatings including color, gloss, haze and transparency.

UV and visible spectrometers measure the amount of ultraviolet (UV) and visible light transmitted or absorbed by a sample placed in the spectrometer.

X-ray fluorescence spectrometers (XRFs) use a spectroscopic technique that is commonly used with solids, in which X-rays are used to excite a sample and generate secondary X-rays. 

Infrared (IR) spectrometers measure the wavelength and intensity of the absorption of infrared light by a sample.

Mass spectrometers separate ions by their mass-to-charge (m/z) ratios. They are used to identify compounds by the mass of one or more elements in the compound. They are also used to determine the isotopic composition of one or more elements in a compound.

Fluorometers measure the amount of fluorescent radiation produced by a sample exposed to monochromatic radiation.

Photometers produce electrical signals, which correspond to radiant flux energy, for a series of discrete wavelength intervals. They are used to measure wavelengths of light spectra and optical or atomic emissions.

Raman spectrometers are used to measure the wavelength and intensity of inelastically scattered light from molecules. They can determine the chemical composition of a sample based on its wavelength and intensity.

Specialty or proprietary products and accessories related to spectrometers.

Water quality photometers and colorimeters are ion-specific computer-interfaced probes designed to determine the concentration of a solution from its color intensity.

Turbidity instruments measure the average volume of light scattering over a defined angular range. Both particle size and concentration of suspended solids as well as dissolved solids can affect the reading.

Camera filters provide a range of optical filtering effects in scientific, research, and industrial applications.

Optical apertures and slits control the diameter of beams from light sources.

Machine vision systems are used for automated inspection and measurement in production environments.
