spectrophotometer
A spectrophotometer is a scientific instrument used to measure the intensity of light at various wavelengths in the electromagnetic spectrum, typically in the visible and ultraviolet regions. It is...
abridged spectrophotometer
An abridged spectrophotometer refers to a simplified or compact version of a traditional spectrophotometer, which is a scientific instrument used to measure the intensity of light at different...
absorption spectrophotometer
Measures the absorption or sample transmittance over a range of specified wavelengths. Sample may be placed within the device and the transmission measured to an accuracy of given percent. The...
Brace-Lemon spectrophotometer
A spectrophotometer having a pair of identical collimators with two Glan polarizing prisms, one fixed in azimuth and the other rotatable, set in one collimator. A Brace prism serves as the dispersive...
Dobson spectrophotometer
A spectrophotometer that measures the amount of ozone in the atmosphere through a comparison of solar energy at two wavelengths in the ozone's absorption band. This comparison is achieved by...
double-beam spectrophotometer
A spectrophotometer in which the beam emitted by the radiation source is split into beams that travel through the sample and a reference cell and are subsequently recombined to fall on the detector....
filter spectrophotometer
A spectrophotometer that makes use of filters to isolate narrow bands of the spectrum.
Glan spectrophotometer
A device similar to the ordinary spectrophotometer but containing particular modifications to provide for the comparison of two sources.
Huefner spectrophotometer
A visual spectrophotometer with a rhomb located directly before the entrance aperture of a constant-deviation spectrophotometer.
infrared spectrophotometer
A spectrophotometer having a prism or, more frequently, a grating for the study and recording of infrared spectra. It usually consists of a radiation source such as a Nernst glower, a monochromator,...
Koenig-Martens spectrophotometer
A visual, single-unit spectrophotometer with a biprism and a Wollaston prism. The Wollaston prism polarizes coincident images of the two halves of the entrance aperture.
microspectrophotometer
A specialized spectrophotometer for use through a microscope on very small areas of an object.
photoelectric spectrophotometer
A system that consists of a spectrophotometer with a photoelectric detector for measurement of radiant energy.
reflectance spectrophotometer
An instrument that spectrally analyzes the flux reflected from a material. The reflected flux may be total, diffuse or specular. Often the instrument measures the reflectance factor instead of the...
actinometry
Actinometry refers to the measurement of the intensity of radiation, particularly light, with a specific focus on its ability to cause photochemical reactions. It involves quantifying the amount of...
colorimetry
Colorimetry is the science and technology of quantitatively describing and measuring colors. It involves the precise evaluation of color attributes such as hue, saturation, and brightness, using...
monochromatic illuminator
->
monochromator
A monochromator is an optical instrument used to isolate and select a narrow range of wavelengths from a broader spectrum of light. The term monochromator is derived from "monochromatic," meaning...

optical manufacturing tools and machinery
Optical manufacturing tools and machinery encompass a wide range of equipment, instruments, and systems used in the fabrication, shaping, finishing, and testing of optical components and systems....
spectral repeatability
Spectral repeatability refers to the consistency and reproducibility of spectral measurements across multiple trials or instances. It is a measure of how well a measurement instrument or system can...
spectrochemical equipment
Equipment used for chemical analysis by investigation of the spectra formed and observed in chemical activity. Of particular use are spectrographs for recording the emission spectra of substances...
spectroreflectometer
A spectrophotometer specially designed to measure spectral reflectance.
ultraviolet spectrometer
A spectrophotometer designed for use in the 200- to 380-nm range of the electromagnetic spectrum and equipped with a calibrated scale to determine wavelength.
