feature of product

Apply versatility. Can test solid surface reflections and fluorescence, as well as backscatter and fluorescence of liquid and powder samples.

Multiple probe options. The collar material can be selected according to the user's requirements. The design of the probe optical window is also available in standard and 30° angles.

The F400-7, F200-7 and F600-7 probes are all composed of 7 strands of optical fiber bundled tightly together. The collar is made of stainless steel. Among them, 6 strands are lighting fibers and the middle strand is readout fiber. The diameter of the fiber in the F200-7 probe is 200 μm, the diameter of the fiber in the F400-7 probe is 400 μm, and the diameter of the F600-7 is 600 μm.
