Claims (3)
- 음극선관노광장치에 이용하는 광량보정필터에 있어서, 그 유효면부를 다수의 소구화들로 분할하여 각각의 소구화를 정방형의 불투명부분과 투명한 그 외의 부분으로 나누며, 상기 불투명부분들의 폭을 바꾸어 소망하는 투과율분포를 갖도록 하고 동시에 정방형의 소구화들 및 불투명부들의 배열을 음극선관의 수평방향에 대하여 소정의 경사각도로 기울인 것을 특징으로 하는 음극선관노광장치의 광량보정필터.
- 제1항에 있어서, 상기 경사각도를 45°로 한 음극선관노광장치의 광량보정필터.
- 제1항에 있어서, 상기 정방형의 소구화의 한 변의 길이를 100~250㎛으로 한 음극선관노광장치의 광량보정필터.
