APD430 series of free-space APD photodetector modules, wavelength range covering the visible and near-infrared region, can be used to replace Thorlabs the same model parameters; suitable for free-space optical applications detection, such as LIDAR.
The YB-LASER-1550-1 is a human-eye safe 1550nm high peak pulsed laser that achieves kW-level peak power, ns-level pulse width laser output, and self-monitoring light, making it ideal for use as a TOF LIDAR emission source.
