Pyroelectric Detectors for Infrared Spectrometers - D31/D41 Series

17 Jul 2018

LASER COMPONENTS is a leading manufacturer of Deuterated L-Alanine doped Triglycine

Sulphate (DLaTGS) pyroelectric detectors for infrared spectrometers. From our research and

production facility in Florida we supply customers all over the world with these industrial

grade detectors.

DLaTGS has several advantages over standard TGS, the material is doped with deuterium to

raise the Currie temperature to 61 degrees centigrade, while doping with L-alanine prevents

permanent depoling after excursions above the Currie temperature. These features make

DLaTGS one of the highest performing pyroelectric materials available today.

The devices are manufactured in standard TO style packages that can be fitted with a range

of windows including CaF2, KBr, BaF2 and ZnSe-Ar. Thermoelectric coolers can also be supplied

in TO-99 and TO-37 packages. The TEC can be used to tune the detector temperature

to maintain maximum responsivity.

FTIR spectroscopy was developed to overcome the slow scanning limitations encountered

with dispersive elements and so, ideally, the interferogram needs to be processed quickly.

The broad spectral response and short time constant of DLaTGS makes it ideal for this

application - our D31/D41 series of voltage mode devices are specifically designed for this

application.
