TILDAS - Tunable Infrared Laser Direct Absorption Spectroscopy

TILDAS is a dual laser trace gas analyzer configured for the simultaneous detection of N2O, CO, and H2O with one laser and CH4, and C2H6 for other laser with a 76 m optical multi-pass cell.

It is a strongly modified commercial instrument designed to operate on IAGOS-CARIBIC aircraft A350-900. Worldwide unique is the optical box located in a hermetically tight pressure housing what guarantees constant pressure conditions to avoid pressure induced optical fringes.
