Research on Automatic Technology of Debugging and Assembling Optical Fiber Collimator

Abstract:

In order to improve the efficiency of debugging and assembling optical fiber collimator and to facilitate mass production, Automatic assembly technology of optical fiber collimator was studied. A new method was proposed to assemble optical fiber collimator by detecting minimal receiving beam spot. First, the relation was analyzed between the detected spot radius and the distance from the emitting end to reception end according to Gaussian beam transmission theory. Then, an automation system was designed to detect the minimal receiving beam spot when the distance was suitable. The optical fiber collimator was successfully assembled after being fixed. Experimental results show that the coupling loss between two collimators is less than 0.53dB when the wavelength of the transmitting light is 1550nm and the distance between two collimators is less than 1 mm.
