4.3 Sample compartment
The sample compartment can be accessed by lifting the blue top lid. For calibration pur-
pose the sample compartment can accommodate e.g. a 10 cm calibration gas cell. This
gas cell is fixed by 2 retaining clips.
How to insert the gas cell is described in chapter 5.5.
4.4 Beamsplitter lid
The spectrometer is equipped with a permanently-aligned Michelson interferometer,
cube-corner mirrors and a beamsplitter.
The interferometer has a 30° angle of incidence. This narrow angle of incidence makes
more effective use of the beamsplitter and reduces polarization effects.
How to change the beamsplitter is described in chapter 5.8.
