1 um Isolator (1 um-5W)
High-power 1 um-band fiber isolator covering 1054-1074 nm at up to 5 W input power.
Technical overview
Shinkosha lists this as a new product in its fiber-laser isolator line. It covers 1054-1074 nm at up to 5 W input power, with insertion loss below 1.2 dB, isolation above 30 dB across the band and a polarisation extinction ratio above 25 dB. It is supplied on passive 10/125 PM fiber or the core-10 fiber series in a 75 x 14.3 x 20.6 mm housing. The published outline drawing adds two M2 mounting holes at 2.5 mm depth on a 12 mm pitch and a 5 mm fiber boot.
