Development in optical technology has played a major role in the evolution of miniature spectrometers. Charge-coupled devices (CCDs) are the detector of choice for miniature spectrometers, offering the advantages of small size, modest pricing, and suitable sensitivity for a wide range of applications. Coating the CCD array with a phosphor to absorb UV light and emit visible light results in a detector with good UV response for many applications. With the ability to combine high-pass and low-pass linear variable filters, manufacturers could use the dichroic technology to spectrally shape the excitation energy from broadband sources used for cuvette-based fluorescence. Diffraction gratings of various designs are common to spectrometers, including flat-ruled gratings and holographic gratings. Silver-coated mirrors have very high reflection values of greater than 97% across visible and near infrared wavelengths, and over a wide range of angles of incidence. Source

Spectroscopy is the study of the interaction of light with matter. By observing how light interacts with matter-through reflection, refraction, elastic scattering, absorbance, inelastic scattering, and emission-it is possible to (1) identify the wavelengths of light that interact with atoms and molecules, or (2) quantify the amount of light being absorbed, reflected, scattered, or emitted at a particular wavelength. This unit describes the background and basic principles of spectrophotometry (the study of the reflection or transmission properties of a substance as a function of wavelength), in particular, absorbance spectrophotometry. Also included is discussion of key spectrophotometer components and their functions, the relationship between absorbance and transmittance, experimental considerations, and the steps necessary in preparing a standard curve for determining absorbance concentration. © 2012 by John Wiley & Sons, Inc.
