Raman Probes

Matching the high throughput Raman spectrometers, Wasatch Photonics offers a Raman probe with a very high flexibility. All Raman probes already come with an integrated filter set.

Excitation Wavelength	532, 638, 785, 830, or 1064 nm
Collection Optics	f/1.3
Laser Spot Size	~170 µm
Collection Area	1 mm diameter spot when using 600 µm collection fiber
Collection Distance	11 mm (lens to sample)
Laser Band Pass Filter	3 nm bandwidth, >OD 6 out of band rejection
Long pass/Edge Filter	>80% transmission, laser line blocking >OD 6

The flexibility is primarily achieved by the unscrewable probe shaft. With corresponding adapters, it can be adapted to the Thorlabs system (SM05), for example. This allows a variety of new measurement geometries to be realized very easily and very cost-effectively. With the help of these adapters, lenses with different focal lengths or microscope objectives (Thorlabs SM1 + Thorlabs RMS adapter required) can now also be used. Wasatch Photonics already offers a standard lens set with the corresponding adapter and 3 lenses with different focal lengths.

As a further highlight, the Ballprobe® from Marqmetrix can also be adapted via an adapter. This special probe with ball lens is perfectly suited for industrial use with powders, pastes and liquids.
