DLaTGS Pyroelectric Detectors

01 Nov 2017

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.
