Embodiment Construction
[0018] As used herein and in the claims, "comprising" means including the following elements but not excluding others.
[0019] Referring to Fig. 1, Fig. 1 shows the device of the present invention in the post-filtered transmission mode.
[0020] The transmission mode system generally includes an excitation light source 28 , a laser line filter 30 , a collimating lens 32 , an optical module 42 , a detector 24 , a signal processing unit 40 , a microprocessor 26 and a computer readable storage medium 44 . The detector 24 is connected to a signal processing unit 40 which is in turn connected to a microprocessor 26 . Computer readable storage media 44 is connected to microprocessor 26 .
[0021] The excitation light source 28 is used to emit at least one excitation wavelength λ E The excitation light passes through one or two laser line filters 30 and reaches the sample 20 to be measured. Due to the excitation light, an optical signal, in particular a Raman signal, is emitted f...
