DragonFly (DF) series spectrometers are low cost near infrared models which combine OtO Photonic's expertise in spectrometer cavity design with Texas Instruments' DLP® technology.
DragonFly is offered with a choice of 1mm active area InGaAs photodiodes for operation over 900-1700nm (DF1514) or 1340-2280nm (DF1824).
This innovative arrangement provides an extremely compact form-factor with an overall size (including connectors and control boards) of only 108cm³ (DF1514, 900-1700nm) and 184cm³ (DF1824, 1340-2280nm).
Despite its compact form-factor DragonFly features an extremely rigid optical bench ensuring a platform with excellent thermal, humidity, shock and vibration stability.
