All FEMTO photoreceivers offered with FS input (round flange with 25 mm diameter) are now also available with 1.035″-40 threaded flange (FST) input – for even more flexibility on the optical bench!
The new external threaded free-space input (FST) will be delivered together with a matching internal threaded coupler ring offering a broad compatibility with lenses, tubes, cage systems and other accessories from various manufacturers. For example converting the free-space FST input to an optical fiber input is easily done by screwing on the optionally available FEMTO fiber adapters (PRA-FC and PRA-FSMA). A helpful tool for doing this would be the convenient spanner wrench AT-W1.
FEMTO fiber adapters are recommended for photosensitive areas of 0.4 mm diameter or more (coupling efficiency may be compromised for photodiodes with smaller diameter).
Existing FEMTO photoreceivers with FS-input can be converted to FST-input by FEMTO. Please contact us for further information.
