Patent number: 11251579Abstract: A laser collimating module includes a heat dissipating base having a fixing element on a top thereof and a plurality of pins at a bottom thereof, a laser diode chip disposed on the fixing element, a cap covering on the heat dissipating base with a placing space therein and an opening on a top thereof, and a cylindrical lens disposed in the placing space. The opening of the cap is connecting to the placing space and aligning with the laser diode chip correspondingly. The cylindrical lens has a first surface facing toward the laser diode chip with a first minimized distance arranged therebetween and a second surface facing toward the opening with a second minimized distance arranged therebetween. The laser diode chip is stimulated and emits an elliptical laser beam, and a light emitting angle is formed. As the elliptical laser beam passes through the cylindrical lens, the light emitting angle is narrowed and the laser beam is collimated to be a linear beam.Type: GrantFiled: October 4, 2019Date of Patent: February 15, 2022Assignee: Arima Lasers Corp.Inventors: Cheng-Tsung Tseng, Ming-Hui Fang

Patent number: 10418780Abstract: A dot projector with automatic power control includes a housing covering a substrate with an installing space and a platform therein, an automatic power control integrated circuit, a photodiode and a reflector disposed under the platform of the housing, a collimator disposed in the installing space of the housing and a diffractive optical element bonded on the platform of the housing. Whereby a laser diode emits a laser light to the reflector for the laser light to be reflected perpendicularly through the collimator to the diffractive optical element; then the diffractive optical element produces a plurality of light spots and the a stray light is also produced from the laser light. The photodiode of the automatic power control integrated circuit then detects the stray light and produces a feedback signal transmitted back to the laser diode for adjustment of the laser emission power in order to control the light spots produced by the diffractive optical element.Type: GrantFiled: July 19, 2018Date of Patent: September 17, 2019Assignee: Arima Lasers Corp.Inventors: Jung-Min Hwang, Chia-Hung Hsieh, Chun-Ting Lin, Ming-Cho Wu, Ming-Hui Fang
