Abstract

본 발명은 광픽-업 액츄에이터의 대물렌즈 경사측정장치에 관한 것으로서 레이져장치(10)에서 조사된 레이져광을 대물렌즈(32)상에 안치된 전반사 미러(33)에 조사하여 대물렌즈(32)상에 안치된 전반사 미러(33)에 조사하여 대물렌즈(32)의 경사각도를 측정하는 장치에 있어서, 상기 레이져 장치(10)에서 주사된 레이져 광을 90도 굴곡시키기 위해 45도 경사져 설치되는 반사거울(20)과, 상기 반사거울(20)에서 굴곡되어 전반사미러(33)로 입사되는 압사광을 초점 위치를 조절하기 위해 광픽-업 액츄에이터(30)를 x 축 방향 및 y 축 방향으로 이동시키는 트랜스레이터(40)와, 상기 전반사 미러(33) 사이에 설치된 스크린(50)으로 구성된 것을 특징으로 하는 광픽-업 액츄에이터의 대물렌즈 경사사측정장치인바, 측정작업이 신속하고 정확할뿐만 아니라 측정에러를 줄여주도록 해준다.The present invention relates to an objective lens tilt measuring apparatus of an optical pick-up actuator, which irradiates a laser beam irradiated from the laser apparatus 10 onto a total reflection mirror 33 placed on the objective lens 32 to form an image on the objective lens 32. In the device for measuring the inclination angle of the objective lens 32 by irradiating the total reflection mirror 33 placed in the, reflection mirror which is installed at an inclination of 45 degrees to bend the laser light scanned by the laser device 10 by 90 degrees And a translator for moving the optical pick-up actuator 30 in the x-axis direction and the y-axis direction to adjust the focus position of the incident light that is bent in the reflective mirror 20 and incident on the total reflection mirror 33. The objective lens tilt measuring device of the optical pick-up actuator, characterized in that it is composed of a 40 and the screen 50 installed between the total reflection mirror 33, the measurement operation is not only quick and accurate, but also reduces the measurement error It allows you to.
