Owners of the very popular microscope based Raman
spectrometer systems (almost always based on spectrographs and CCD detectors) examine
samples by back-scatter using their microscope objectives as both laser focussing lenses
and at the same time scattered light collector. When analysing samples at the microscope
level, these instruments are unequally valuable but for routine use they do suffer from
the limitation that the sample must be small enough to 'fit' beneath the objectives. Now a
microscope is designed to 'look' at small objects - big ones have to be reduced in size to
become accessible.
The Ventacon Macro-Micro accessory converts a microscope
Raman into a macroscopic system. The change is fully reversible so users have the 'best of
both worlds'. The accessory consists of a mirror/lens assembly and macro sample holders.
In fact, the accessory stage enables users to fit the full range of Ventacon accessories
- hot cells, cryogenic cells, bottle holders etc. The mirror/lens assembly screws into one
of the threaded apertures in your microscope objective turret and carries a reflector
turning the optic axis from vertical to horizontal.
