Fiber Optic Reflectance Probe for StellarNet, Ocean Optics, Avantes specrometers

Description

This Fiber Optic Reflectance Probe (R400-7-UV/VIS ) for spectrometer measurements has 6 optical UV-VIS fibers that illuminate a sample, bundled around 1 400μm read fiber that sends the reflected light from a sample to a spectrometer.
For reflectance measurements the 7 exterior fibers are illuminated by a high output power fiber optic UV-VIS light source and the center read fiber collects the reflected light and returns the signal to the spectrometer. The probe is typically used to measure color using a 45 degree angle (diffuse reflectenace) and also thin film measurement using a 90 degree angle (specular reflectance).
The fiber connecting the probe has steel monocoil protection in a black PVC jacket. Each of 2 legs terminate with SMA905 fiber optic connectors. The total length of the fiber plus probe are short as works best to pass UV light.
