UV-induced fluorescence is one of the most robust techniques used for rapid real-time detection of biological aerosols. [105] The first UV sensors were lasers lacking in-field-use practicality. In order to address this, DARPA incorporated SUVOS technology to create a low-cost, small, lightweight, low-power device.
Using the Bausch & Lomb Spectronic 20 Colorimeter, 1962. The Spectronic 20 is a brand of single-beam spectrophotometer, designed to operate in the visible spectrum [1] across a wavelength range of 340 nm to 950 nm, with a spectral bandpass of 20 nm.
