The major featRS-LiDAR-M1 Family Features: 125 laser beams with exceptional performance: the RS-LiDAR-M1 has a field of view of 120°*25°, which is the MEMS solid-state LiDAR’s largest field of view among released products worldwide. fiber-optic-transceiver-module. Вносимые потери (IL). 1550nm Tunable Laser; 1650nm Tunable Laser; 1550 nm High Power DFB Laser; 15xx nm High Power Diode Laser; Multichannel Tunable Laser Source; Multi-Section Laser Controller; Photodetectors. These feature high sensitivity to near-infrared wavelengths. Portée des lidars fibrés ONERA @1. The CWDM reverse optical transmitter is. The development targets applications such as LIDAR and range finding, which require eye-safe, coherent light sources with a high peak-power. But he said it isn't the only company exploring that combination: Pleasanton. This product line is a family of state-of-the-art high-performance 1550 nm externally-modulated CATV fiber optic transmitters. In emerging FMCW lidars, Si photonics can be used in coherent receivers. Bandpass Filter Specifications | F-1550-12-25. 3mrad Point interval: 6. 5 nm center wavelength (CWL), a 1. The program reconstructs the wavefront from a spot pattern obtained with hexagonal, orthogonal or random Hartmann (-Shack) mask with arbitrary number of subapertures. In addition, InPhenix 820nm, 1310nm and 1550nm Gain Chips can be used as a gain medium for Single FBG Lasers or Externally Tunable Cavity Lasers. The PLDBR1550PA includes an integrated opt. This pulsed laser is ideal for applications in LiDAR, range finding, 3D scanning and fiber sensing, etc.
