3.8 Inserting beamsplitter
During initial installation, the beamsplitter needs to be inserted. All beamsplitter types
available for the spectrometer are electronically coded, enabling the spectrometer firm-
ware to auto-detect the beamsplitter type currently installed.
The data about the beamsplitter type are transferred to the spectroscopy software.
3.8.1 Handling instructions
• Do not touch the beamsplitter surface as the beamsplitter may become useless.
Always hold the beamsplitter on the two knobs (A in figure 3.4a).
• The surface of some beamsplitters (especially KBr beamsplitters) is hygro-
scopic. Never expose them to humidity, water or aqueous solutions. Always
store the beamsplitter in a sealed container and in dry environment, e.g. in the
beamsplitter storage box. Fix the protective covers onto the beamsplitter
(figure 3.4b). The covers provide mechanical protection, but do not protect
against humidity!
• Do not try to loosen or fasten the screws (B in figure 3.4a) as this will impair the
optical quality of the beamsplitter.
• Do not try to clean the beamsplitter. This will definitely damage the beamsplitter
irreversibly.
• Do not expose the beamsplitter (especially beamsplitters made of KBr) to large
temperature changes. In particular, a cold KBr beamsplitter must not be exposed
to a warmer ambience, as this will lead to condensation of humidity.
NOTE
Inadequate handling:
Beamsplitter may become useless.
➣
Handle the beamsplitter with utmost care to ensure long service life.
➣ Observe the handling instructions described in chapter 3.8.1.
