Description
Reliable planar GaAs photodiodes are packaged in hermetically sealed cans with a flat glass window or a ball lens. KPDG008 has the sensitive area of 80μm dia. Which allows to couple with a multi mode fiber efficiently through the ball lens cap. A pigtail type is available as an option for both devices.
