LASER COMPONENTS offers the new Si-thermopile from Dexter Research Center. This new thermopile has an active area of 1.2 x 1.2 mm and high output signals. Due to the small size of this module, four optically separated thermopiles can fit into a TO-5 housing that has a diameter of 9 mm. An SMD compatible housing is now available for the individual detector.
Compared to its predecessor, the ST120 QUAD – as a multi-colour detector with reduced active area and high output voltage – reaches twice the signal.
