Dual Input Probe

The InPhotonics dual-wavelength probe allows the user to switch between 532 and 785 nm excitation wavelengths, without having to align multiple probes onto the sample. Both wavelengths focus onto the sample at the same spot. Based on our patented RamanProbe optical layout, the dual-wavelength design offers excellent collection efficiency and strong attenuation of the Rayleigh line for high-quality, background-free spectra.

The probe comes standard with FC or SMA receptacles and 4 fiber jumpers. The spot size of the probe may be changed by changing the size of the excitation fiber jumpers, and the probe is designed to work with our compact sample holder for routine laboratory measurements.
