Claims (3)

  1. 재물대 위에 놓인 작은 물체를 조명광원을 이용하여 반사 또는 투과시키면서 투사렌즈로서 확대시켜 스크린에 고배율로 확대 투영시키는 장치에 있어서, 상기 작은 물체(16)를 관찰하고자 하는 광원을 물체 조명용 광원(11)과, 스크린(26)에 투사시키는 투사용광원(22)으로 분리되게 구성하며, 상기 조명용 광원(11)으로부터의 빛이 재물대(15)상의 물체(16)를 투과하여 대물렌즈(20)를 통하여 액정라이트밸브(21)에 확대결상시키고, 여기에 상기 투사용 광원(22)을 조사시켜 투사렌즈(24)로서 재차 확대시켜 스크린(26)에 투영시킬 수 있게 한 것을 특징으로하는 고배율 확대 투영장치.
  2. 제1항에 있어서, 상기 조명광원(11)에서 조명하는 광원을 투과식 조명과 반사긱 조명을 선택적으로 할 수 있도록 선택거울(13)이 소정의 각도로 회전가능하게 설치된 것을 특징으로 하는 고배율 확대 투영장치.
  3. 제2항에 있어서, 상기 선택거울(13)을 반사식 조명으로 할때 조명광원(11)에서 나와서 집광렌즈(12)를 통과한 평행광을 반사시키는 전반사거울(17)을 소정각도로 각도조절 가능하게 설치한 것을 특징으로 하는 고배율 확대 투영장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
