Raman Probe - Fiber Optic Coupled Raman Probe for Laboratory Applications

Request for information

The Raman Probe uses efficiently focused and filtered optics in a compact probe design. Therefore, the probe is an interesting tool in numerous Raman laboratory applications. The focused set-up of the optics allows to measure through glass or plastic receptacles. Different focal distances can be chosen. However, it is fixed by the factoy.

The Raman Probe is available for various excitation wavelengths in the visible or near infrared range. Via optical fibers the probe can be connected to the spectrometer using SMA or FC connectors. Due to the high attenuation of scattered light (108) an additional filter in the spectrometer is no longer necessary.

Should you require information about further possibilities of configuration, please do not hesitate to contact our application scientists.
