Abstract
A coupling method of an optical module is provided. A circuit board with a light emitting element emitting an output light and an output lens are provided. The light emitting element is covered by the output lens. The output lens is connected to an output meter. The output lens and the circuit board are moved relatively. An intensity of the output light is measured by the output meter. An output qualified region is defined based on a region where the output lens is located when the intensity of the output light is greater than an output requirement. The aforementioned steps are repeated for a predetermined number of times. The output lens and the circuit board are moved relatively in an intersection area of the output qualified regions. The output lens is fixed on the circuit board when the intensity of the output light is greater than the output requirement.
