Rotadata's collimated optical probe model provides a robust and proven solution for most sub 350°C compressor or fan applications requiring increased working range. Our collimated probe is designed to ensure that the working range is optimised to the application and special working ranges can be specified on order, and it consists of either an ST or SMA905 optical connector to suit, a flexible ruggedised stainless steel exterior to protect the optical fibres and a solid stainless steel tip which houses a high quality optical lens assembly to focus the optical output dramatically increasing the optical efficiency and working range.

Rotadata are an AS9100:D & ISO9001 2015 accredited company, offering design and manufacture, project management and collection and delivery services within the UK and world-wide by arrangement.
