OtO Photonics’ PocketHawk series of crossed-cavity Czerny–Turner spectrometers operating from 330 nm to 1050 nm come in a package of just 65 × 65 × 25.2 mm3 (<107 cm3), including the external control board. They utilise a high-sensitivity, 3000-pixel CCD sensor with a choice of slit sizes from 10 µm to 200 µm giving FWHM resolution in the range of 2.2–12 nm over the spectral range of 330–1050 nm. A choice of two 500 grooves/mm gratings blazed at 330 nm (VNIR6) and 770 nm (VNIR6A) allows users to specify the optimum sensitivity grating to suit their application. Communication with PH-Series spectrometers is via high speed (480 Mbps) USB2.0 or six user-programmable digital I/Os.
