Claims (1)

  1. 칼라 수상관의 형광면 형성에 사용되는 노광광원에서 방사되는 빛의 궤도를 칼라 수상관의 전자총에서 방출되는 전자 비임의 궤도와 비슷하게 하기 위한 보정 렌즈의 제작시에 상기 보정 렌즈의 유효면을 복수의 영역으로 분할하고 그 분할된 복수의 각 영역에 대하여 상기 전자 비임의 궤도에 대하여 상기 빛의 궤도 추적을 행하여 상기 복수의 각 영역에 대하여 동일한 표현 형식의 표면식을 하나씩 결정하여 그 복수의 각 영역에 대하여 결정된 복수의 표면식에 의해 표시되는 렌즈의 유효면을 허용오차 이하로 표시하는 하나의 표면식과 비슷하게 하여 그 하나의 표면식에 의거해서 보정렌즈를 제작하는 것을 특징으로 하는 칼라 수상관의 형광면 형성용 보정렌즈의 제작방법.
