Abstract: A laser module is provided and includes a laser unit, a focusing lens, an electric device, and a temperature control device. The laser unit is configured to emit a laser light. The focusing lens corresponds in position to the laser unit, and the focusing lens is configured to converge the laser light emitted from the laser unit so as to outwardly output the laser light. The electric device includes a focusing ring, a voice coil motor, and a motor base. The voice coil motor is configured to drive and move the focusing lens in a straight line toward or away from the laser unit with the focusing ring. The temperature control device is mounted on the laser unit and includes a thermoelectric cooling module and a thermistor. The thermoelectric cooling module is configured to cooperate with the thermistor to adjust a working temperature of the laser unit.

Abstract: Disclosure is related to a sensing module and a Laser device using the sensing module. The sensing module is adapted to a Laser module. The sensing module essentially includes a beam splitter and a photo sensor. This beam splitter is disposed at an optical-axis path of laser beam. The splitter is used to split the laser beam into a transmissive beam and a reflective beam. The photo sensor however is disposed apart from the optical-axis path of the original laser beam. The photo sensor converts the sensed photo signals into electrical signals which are as feedback signals to the laser module.

Abstract: A surface-emitting laser diode module having improved focusing performance includes a main body, a first support member, a second support member, a laser diode chip, and a focusing lens. The first and the second support members are disposed on the main body. One end of the first and the second support members is exposed in a trough formed on the main body. The other ends of the first and the second support members protrude from the main body and form a respective soldering portion. The laser diode chip is disposed on the first support member exposed in the trough and connected electrically to the second support member. The focusing lens is arranged at the light exit aligning the laser diode chip. The thinner and lighter laser diode module can provide better focus for dot or line laser applications.

Abstract: A laser assisted positioning mechanism includes a cover, a laser module, a lens, an adjusting device and a plurality of cell holders. The cover includes a lower cover and an upper cover, and the lower cover has a hollowing supporting rib formed in a center thereof. The laser module is disposed in the cover. The lens is disposed on the lower cover of the cover in conjunction with the laser module. The adjusting device is connected with the laser module and exposed outside the upper cover. The cell holders are disposed in the cover, respectively receiving cells, and electrically connected with the laser module. Accordingly, the laser assisted positioning mechanism can be assembled and mounted on a circular saw machine and emit laser to cut materials by aligning with a desired cut line for assisting the cutting operation.

Abstract: A laser guiding device for machine tools includes a casing, a circuit board and a laser module. The casing includes a base with a through-hole and a top cap covering the base. The circuit board is disposed on the base. The laser module is disposed on the base and electrically connected with the circuit board. The laser module is disposed corresponding to the through-hole of the base. An elastic body and a thread adjustment element are respectively disposed beneath and on the laser module and respectively abut against a bottom and a top of the laser module. Accordingly, the present invention can adjust the angle of the laser module via locking or releasing the thread adjustment element so that laser light is emitted along the correct direction.

Abstract: A support assembly for a counter weight of a laser level is disposed in a main body of the laser level for supporting the counter weight with a laser module mounted therein in the main body. The support assembly includes a fixing unit and a universal bearing. The fixing unit is disposed in the main body and the universal bearing is mounted in the fixing unit. The counter weight has a shaft portion formed on an upper end thereof and connected with the universal bearing. The counter weight is swingingly supported in the main body by the universal bearing. Basing on the structure, the present invention has a simple structure for easy assembly and disassembly, thereby being manufactured, maintained and corrected conveniently.

Abstract: The present invention relates to a measure module. The measure module is installed on an inclinable machine tool. The machine tool has an inclinable member. The measure module includes a monitor and a sensor. The sensor is electrically connected with the monitor. The sensor is installed on the inclinable member. As a result, when the machine tool is adjusted to an angle, the measure module can display the angle via the monitor. It can achieve the adjustment of the angle quickly and accurately.

Abstract: A laser module with trimming capacity has a base having an indented portion formed thereon so as to be non-annular in configuration. A lens is disposed inside the base. A laser diode is disposed inside the base and behind the lens. A printed circuit board electrically connects the laser diode. Alternatively, the base has a polygonal rotation portion, instead of the indented portion, disposed on an external surface thereof.
