An optical spectrometer (spectrophotometer, spectrograph or spectroscope) is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials
A monochromator is an optical device that uses a mechanically selectable narrow band of wavelength to form an image. (sometimes a specific spectrum of colour) This allow a more accurate measurement. We provide monochromator of a wide variety of focal lengths, from 180mm (Gemini 180) to 1.25m (1000M).
We distribute our monochromators, imaging spectrographs & detectors from HORIBA
