ABSTRACT:
The optical module includes a sensing member, a main body and an adjustable mechanism. The sensing member includes an optical sensor. The main body guides an external light beam into the optical sensor. The adjustable mechanism is disposed at first edges of the sensing member and the main body for combining the sensing member with the main body and adjusting the relative distance or angle between the optical sensor and the external light beam. The adjustable mechanism includes a first adjustable element and a second adjustable element. The unit adjustable amount of the adjustable mechanism is equal to a difference between a first unit displacement of the first adjustable element and a second unit displacement of the second adjustable element.
