How to build your own PIA

Component list and example LabVIEW program for building a photoinduced absorption (PIA) setup.

List of components

Light source: Double QTH/IR source B-ILD-QH-IR-24
(Bentham product page)
Monochromators (one to be coupled with QTH/IR): MSH-300M (motorised slits), gratings MSG-T-1200-500, MSG-T-600-1250, MSG-T-300-3000
(QD Europe)
Cobolt lasers 06-MLD with heat sink
(Hübner Photonics)
Low noise current preamplifier: Stanford Research Systems Model SR570
Lock-In amplifier: Stanford Research Systems Model SR860
Detectors:
- Si biased Thorlabs detector DET10A/M
- InGaAs Thorlabs detector DET10D/M
- InSb IS-2.0 from ACAL
Lenses or mirrors to focus white light on the sample and further onto the detector depend on the space available and can vary.
