Description
Reliable planar InGaAs photodiodes are packaged in hermetically sealed cans with an AR coated glass window or an AR coated ball lens. KPDE004 has the sensitive area of 45mm dia. and it can be efficiently coupled with a single mode fiber through a ball lens cap. The pigtail type, KPDE004T is available with various industry-standard connectors.
