Features

/K6C Peak emission wavelength: 1.45 µm /K6C High radiant output power /K6C Narrow directivity (L7850-01)

Applications

/K6C Light source for moisture meter /K6C Light source for photosensitive material LED Infrared LED Peak emission wavelength: 1.45 µm L7850 series L7850 series is a long wavelength LED using an InGaAs chip. Peak emission occurs at 1.45 µm, making L7850 series ideal for dete ction of water content or moisture. L7850-01 has a glass lens window for narrow directivity (beam spread).
