Mini immersion probe

For absorption measurements in small centrifuge tubes or test tubes, Avantes has launched a pocket sized immersion transmission probe with a length of 130mm and a diameter of 3.2 mm. The optical path of this probe is fixed at 5 or 10mm and can be used in the wavelength range of UV/VIS/NIR (200-2500nm). Generally, the sleeve material of the probe is ME made of chrome plated brass. As an option, longer stainless steel probes or Hastelloy material probes can also be selected. The probe has 2 SMA connectors (FC/PC connectors are optional), which can be easily connected to Avantes' full range of spectrometers and light sources.

If you have any special needs, please contact us.

technical data
Fiber bundle 1 illumination and 1 detection fiber, both with a core diameter of 200 μ m and a standard length of 2m
wavelength range 200-2500 nm (UV/VIS/NIR)
Light connector 2 x SMA 905 connectors
Probe tip 316 stainless steel cylinder, 130 mm (length) x 3.2 mm (1/8 inch diameter). The probe end includes a sampling gap of 5mm physical/10mm optical path or 2.5mm physical distance/5mm optical path. Optional - HY (Hastelloy C276) material.
optical sleeves The optical fiber is protected by a silicone inner tube and a flexible stainless steel (BX, outer diameter 6.0mm) or chrome plated brass (ME, outer diameter 5.0mm) outer tube. Sleeves can also reduce the pressure on optical fibers.
operation temperature -40℃ to 100℃. (HT version 200 ° C)
