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.
