专利汇可以提供Photosemiconductor element专利检索,专利查询,专利分析的服务。并且PURPOSE:To obtain a photoreceptor having high versatility which can be used as a normal photoreceptor and used also as an LD monitor by insulating a detachable cap from a mount base of the photoreceptor, and forming a structure having a terminal not connected to the photoreceptor. CONSTITUTION:A cap 21 has a structure engaged with a circular groove, and a mount base 16 bonded with a photoreceptor is formed of metal. The photoreceptor is of a photodiode in many cases, and the cathode side is bonded to the base 16 to be conducted. Terminals 18, 19 are insulated form the base 16, and a terminal 20 is conducted with the base 16. A terminal 19 is connected to the other terminal of the photoreceptor, and in case of the photodiode, it is connected to an anode. A terminal 18 is not connected to the other, and is used when the photoreceptor is used as an LD monitor, and when used as a normal photoreceptor, the terminals 19, 20 are used. The photoreceptor to be used may be includes a PIN photodiode and an avalanche photodiode.,下面是Photosemiconductor element专利的具体信息内容。
