Mini Transmission Immersion Probe

The Mini Transmission Dip Probe is a miniature transmission probe for absorption measurements.
The miniaturised tip of only 3.2mm (1/8") diameter enables sampling in most miniaturised centrifuge tubes available on the market.
The Mini Dip Probe has a 10mm optical path length and can be used in the UV/VIS (200-800nm) or VIS/NIR wavelength range (350-2000nm).
The probe has 2 SMA connectors for convenient coupling to the Avantes line of spectrometers and light sources.
