OtO Photonics’ new HummingBird series are crossed-cavity Czerny–Turner spectrometers operating from 180 nm to 1100 nm. HummingBird offers the performance benefits of classic Czerny–Turner cavity designs in a smaller package of 83 × 75.5 × 26.75 mm3 (<168 cm3), much smaller than OtO’s own SmartEngine Czerny–Turner spectrometer (~360 cm3). Hummingbird is initially offered with a choice of two 2048-pixel sensors. OtO have designed HummingBird to take advantage of a wide range of slit and grating choices enabling optimisation of spectral bandwidth, resolution and sensitivity. Resolutions from as little as 0.2 nm FWHM can be achieved over 100 nm whilst resolution of 1.5 nm is achieved over the full 180–1100 nm operating range. Communication with the spectrometer is via high speed (480 Mbps) USB2.0 or six user-programmable digital I/Os. SpectraSmart software enables setup within minutes, and there is a Software Developer Kit for Windows and example code for Linux to integrate into a broad range of industrial, medical, pharmaceutical and environmental applications.
