Microchannel Electron Multiplier (MEM) MEM 20×90
Youopto microchannel electron multipliers (MEMs) are microchannel plates (MCPs), electronic devices dedicated to detecting and amplifying charged particles and radiation. An MCP comprises millions of ultrathin conductive-glass capillaries, each acting as an independent secondary-electron multiplier. Within application equipment, MEMs amplify weak signals and detect particle coordinate parameters.

40G High-Speed Indium Gallium Arsenide (InGaAs) Photodetector HSPD4040
Optical Detectors
Fiberwdm
Storage Temperature Range TSTG [Typical Values and Absolute Maximum Ratings]: typical:-45~+85; Rated: -55~+85 Operating Case-Temperature Range TC [Typical Values and Absolute Maximum Ratings]: typical:25; Rated: -40~+85 Bias Voltage VR [Typical Values and Absolute Maximum Ratings]: typical:5; Rated: 5~6
HSPD4040 is a high-speed detector module for digital/analog applications. An InGaAs PIN photodiode responds over1250–1650nm with matching electronics. Maximum bandwidth is40GHz, supply+5V, input standard single-mode9/125μm fiber, and RF output a2.92mm connector matched to50ohms. A sealed housing weighs under20g. The description states ROHS2.0 compliance with restrictions on hazardous substances in electrical/electronic equipment. After nearly two years of R&D,广州瑞东 developed two fully domestic high-speed PD products described as exceeding18GHz and40GHz bandwidth. The18GHz version has rise time<20ps and the40GHz PD<8.5ps. Responsivity is described as matching or exceeding comparable Finisar/Thorlabs imports,with well-controlled tail ringing. Without a TIA,the detectors provide very low noise for high-speed communications and femtosecond-laser testing at high cost effectiveness. The company's independently developed linear supply meets research needs for these detectors.
