NPSD1020 (One-Dimensional PSD)
NPSD1020 One-Dimensional Position-Sensitive Detector Locates Light Spot on Photosensitive Chip. The dual PD comprises two highly sensitive photodiodes, with various active areas and package types available. Its unique arrangement and good photoelectric characteristics support background suppression, ranging, alignment and displacement measurement. A one-dimensional PSD detects the coordinates of a light spot's centroid. High resolution, fast response and simple signal processing suit rapid, precise noncontact and alignment measurements of displacement, distance, angle and other quantities convertible to spot position or movement.

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.
