A compact and versatile 20m multipass cell for gas monitoring and absorption spectroscopy.  

Features

  Variable optical pathlength up to 20m

  Volume 0.5 L

  Base length 11 cm

  In-situ variation of optical path length

  Inner tube can be removed without disturbing
    alignment

  Input and output beams are well separated

  Compact  (18 x 12 x 12 cm) and rugged design

Applications

The multipass cell, with variable optical pathlength up to 20m and a base length of 0.11m, is well suited to absorption spectroscopy in scientific research and gas measurements in industrial environments.


Longer pathlength version

A 55m pathlength cell is now available for scientific research and gas measurements.
