It’s a very noisy industry. The pushback on 905 nanometers is nothing new. At lower wavelengths, the transmitter and receiver are capped in the amount of laser power they can emit. The signal to noise ratio is lower, and you can’t get to long range. That was true five years ago. But it’s not the case anymore.
Current semiconductors are transparent to any wavelength above 1000 nanometers, which means we can use silicon and low cost standard processors for our lidar. We also use a single-photon detector, which doesn’t need a lot of light in order to see reflection. So, even with lower laser power, we can still get a reflection from 200 meters away. In contrast, 1550 nanometer systems need a more powerful laser. They also can’t use standard silicon in the detector, which also makes them more expensive. Our performance comes across very clearly, our solution is ten times smaller, and much cheaper than 1550 solutions.
