The engineering behind the recommendation
Why 1535 nm beats 905 nm at range, how much pulse energy a given distance really costs, and where designs usually fail.
Selection guide
905 nm vs 1535 nm vs 1550 nm: choosing a wavelength for ranging and LiDAR
The wavelength decision sets your detector, your eye-safety class, your maximum usable energy and your weather performance. Here is how the three bands actually compare for ranging work.
DetectorsChoosing the receive side: avalanche photodiodes vs PIN photodiodes
Most of a ranging link's margin is recovered at the receiver, not the transmitter. Here is when an APD earns its 10x price, how gain and noise trade off, and what the specification numbers actually mean.
Selection guideHow to choose a 905 nm pulsed laser diode: from range target to part number
A repeatable procedure for turning a range requirement into pulse energy, pulse energy into peak power and pulse width, and peak power into the smallest package that survives your duty cycle.
Have a specification, not a part number?
Send us the requirement - range, target, size, budget - and an engineer will come back with parts and the trade-offs between them.
