Description
Reliable planar InGaAs photodiodes are packaged in hermetically sealed cans with an AR coated glass window or an AR coated ball lens. KPDE008 has the sensitive area of 80mm dia. and it can be efficiently coupled with a single mode fiber through the ball lens cap. The pigtail type, KPDE008T is available with various industry-standard connectors.
