19/00714 Step 2, purchase of light sensors - tender phase in competition

Kort beskrivning

This acquisition applies to purchase of light sensors for use in the sea at great depths.

The desirable light sensors are, according to the Customer's knowledge, not developed or possible to buy off the shelf. The Customer therefore wants to buy light sensors that are being developed to meet our requirements.

The Customer wish to purchase light sensors to use on our research vessels. Today we are using PAR light sensors, which are made for measuring photosynthetic light. PAR sensors and other commercially available light sensors are not sensitive to low light intensities and are therefore not able to measure light levels at mesopelagic depths. We wish to purchase a light sensor that can measure low light intensities (twilight), as found from the photic zone down into the mesopelagic zone (100 to 800 m depth) and at surface during twilight and night.
