Variable Optical Path Immersion Transmission Probe

Name: Variable Optical Path Immersion Transmission Probe
SKU: OFFP-0001

Cat No:OFFP-0001

Description

The distance between the fiber and the scattering disc can be adjusted from 0.25 to 10 mm. Light enters a fiber bundle (typically six fibers, customizable) via a standard SMA905 connector, reaches the probe tip, reflects off a white diffuse material through a preset gap, and enters the detection fiber, which then couples the light into the spectrometer. The detection fiber is centrally placed among the illumination fibers for optimal efficiency. All fibers are encased in a flexible stainless steel sheath, with a stainless steel probe tip. A metal ferrule in the middle divides the fiber bundle into illumination and detection branches, each with an SMA-905 connector.
