We have launched an infrared light-emitting diode with a precision optical designed lens that can achieve collimation of the beam. A collimated beam refers to a beam of light (usually a laser beam) that has a small beam divergence angle, so that the beam radius does not change significantly after a certain propagation distance. The simplest and most common scenario is a Gaussian beam, which indicates that the Rayleigh length is longer than the expected propagation distance. For example, a 1064 nm beam with a beam radius of 1 mm at the waist and a Rayleigh length of approximately 3 m in air can be collimated in ordinary laboratory devices. Due to the fact that the Rayleigh length is proportional to the square of the waist radius, a larger waist radius is more conducive to the long-distance propagation of the beam Its peak emission wavelength at a forward current of 20mA λ The typical value of p is 850nm, and the typical value of radiation power is 5mW, which has the characteristics of long-term reliability and high power. The 850nm infrared light-emitting diode has excellent parallel light characteristics, which can be used not only as a parallel light LED for encoders, but also in industrial grade fields such as motors and industrial equipment robots.
