Title:
LASER SENSOR AND METHOD FOR MANUFACTURING EXTERIOR COMPONENT
Document Type and Number:
WIPO Patent Application WO/2017/183145
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a laser sensor 100 that has a high-precision optical window 53 and has good resistance to dust and water. Provided is a laser sensor 100 provided with a light projection unit 10, a light reception unit 20 for detecting reflected light L2 from an object of detection OB onto which the laser light L1 from the light projection unit 10 has been emitted, and an exterior component 50 for covering the light projection unit 10 and the light reception unit 20, wherein the exterior component 50 has an optical window 53 that allows laser light L1 and reflected light L2 to pass therethrough and a holding part 54 that surrounds the outer periphery of the optical window 53, the optical window 53 and holding part 54 are formed so as to be integrated from a resin that transmits the wavelength band of the laser light L1, the optical window 53 has a pair of opposing curved optical surfaces, the holding part 54 has a gate part 57 at a position that is relatively removed from the optical window 53 and a light blocking part 58 that is at least adjacent to the optical window 53 and blocks the laser light L1 and ambient light.
