LiInSe₂ Thermal Neutron Detector TND-A
This LiInSe₂ thermal-neutron detector uses the company's internally prepared high-quality LiInSe₂ crystal as its neutron-sensitive medium. Lithium in the lattice converts thermal neutrons into charged-particle signals through neutron capture, read by optoelectronics and low-noise electronics. Si-APD or SiPM readout, moderators, shielding and multi-element arrays are configurable. Compact integration suits portable neutron monitoring, space payloads and research instruments. Lithium capture produces the Li(n,alpha)3H reaction, releasing alpha particles and tritium nuclei. Their energy deposition creates readable signals; Si-APD/SiPM conversion, preamplification and digital discrimination produce neutron counts. Energy thresholds, pulse characteristics and structural shielding reduce gamma-background effects.

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.
