Fluorescence Immersion Probe
The Hellma fluorescence immersion probe makes it possible to measure fluorescence outside of a fluorimeter, directly in the medium being investigated. To achieve the best possible separation between the excitation and fluorescence beams, the fluorescent light is captured at a right angle to the incoming beam. A stainless steel casing protects the quartz glass probe head from damage and reduces the amount of incoming ambient light.
A built-in cylindrical concave mirror reflects transmitted light back into the centre of the sample chamber. A flat mirror in the sample chamber increases the yield of fluorescent light.
