본 고안은 영상의 투사거리가 일정하고 화면의 밝기가 균일한 현미경 투영기의 렌즈스크린에 관한 것이다.The present invention relates to a lens screen of a microscope projector with a constant projection distance of the image and uniform brightness of the screen.
현미경 투영기는 미세한 물체나 조직을 확대하여 여러사람이 함께 관찰할수 있는 교육기기이다.Microscope projectors are educational devices that can be viewed by several people by magnifying fine objects or tissues.
통상의 현미경 투영기는 광원부에서 발산되는 평행광선을 수개의 렌즈를 통과시켜 투영기로부터 적정거리에 위치하는 스크린에 투사하는 것이다.A conventional microscope projector is one which projects parallel rays of light emitted from a light source unit through several lenses and projects them onto a screen located at a proper distance from the projector.
본 고안은 이러한 방식과 달리 투영기의 전면에 직경이 상당한 크기의 렌즈스크린을 장착하여 피투사체의 영상이 렌즈 스크린에 투영되도록 하고 있다.The present invention, unlike this method, is equipped with a lens screen of considerable size on the front of the projector so that the image of the projected object is projected onto the lens screen.
이는 스크린에 투사하는 것보다 화면은 작으나 사용이 간편하고 화면이 선명하므로 소수의 학습자를 대상으로 사용하기에 적합하다.It is smaller than projecting on the screen, but is easy to use and the screen is clear, making it suitable for use by a small number of learners.
본 고안은 현미경 투영기의 투사부 전면에 렌즈스크린을 장착하여 피투사체의 영상이 투영되도록하되 렌즈스크린 전체의 화면밝기가 균일하고 영상의 선면도가 높은 렌즈스크린을 제공하고자 하는데 목적이 있는바, 본 고안의 구조를 첨부한 도면에 의거 상세히 설명하면 다음과 같다.The object of the present invention is to provide a lens screen mounted on the front of the projection unit of the microscope projector so that the image of the projected object is projected, but the screen of the entire lens screen is uniform and the image surface of the image is high. When described in detail based on the accompanying drawings the structure of the design as follows.
광원부(3)와 렌즈(4), 반사경(5) 그리고 투사부(6)로 구성된 현미경 투영기에 있어서, 투사부(6)에 미터스커스 렌즈(1)를 장착하되 광원부(3)로부터 미니스커스 렌즈(1)의 내측 표면의 각 지점에 이르는 투사거리가 일정하게 하는 한편, 미니스커스 렌즈(1)의 내측 표면에는 반투명층(2)을 형성한 구조이다.In a microscope projector consisting of a light source unit 3, a lens 4, a reflector 5 and a projection unit 6, a metric lens lens 1 is mounted on the projection unit 6, but the minis from the light source unit 3 are mounted. The projection distance to each point of the inner surface of the lens 1 is made constant, while the translucent layer 2 is formed on the inner surface of the miniature lens 1.
본 고안은 내측 표면에 반투명층(2)이 형성된 미니스커스 렌즈(1)를 렌즈스크린으로 사용하는데 그 특징이 있다.The present invention has a feature of using a mini-scus lens 1 having a translucent layer 2 formed on its inner surface as a lens screen.
제3a도는, 평면 렌즈스크린으로서 광원의 중심으로부터 렌즈스크린의 중심에 이르는 점선표시의 투사거리와 광원의 주연부로부터 렌즈스크린의 주변에 이르는 실선표시의 투사거리가 서로 다르다.FIG. 3A is a planar lens screen in which the projection distance of the dotted line display from the center of the light source to the center of the lens screen is different from the projection distance of the solid line display from the periphery of the light source to the periphery of the lens screen.
따라서 렌즈스크린의 중심부는 화면이 밝고 영상이 뚜렷하나 렌즈스크린의 중심에서 벗어날수록 화면의 밝기와 영상의 선명도가 점차 낮아진다.Therefore, the center of the lens screen is bright and the image is clear, but the brightness and the sharpness of the image are gradually lowered as the lens screen moves away from the center of the lens screen.
그리고 제3b도와 제3c도는 점선표시의 투사거리와 실선표시의 투사거리가 일정하여 반투명층(2)에 맺히는 영상의 밝기와 선명도가 균일하다.3B and 3C, the projection distance of the dotted line and the projection distance of the solid line are constant so that the brightness and clarity of the image formed on the translucent layer 2 are uniform.
다만, 제2b도는 곡면유리를 사용함으로써 렌즈스크린을 통과한 영상이 발산되나 제3c도는 미니스커스렌즈를 사용함으로써 발산광선이 평행광선으로 수렴되며 관찰자에게 피투사체 전체를 선명하게 보여주게 된다.However, in FIG. 2B, the image passing through the lens screen is emitted by using curved glass, while in FIG. 3C, the diverging light is converged into parallel rays by using a mini-cursor lens, and the entire projected object is clearly shown to the viewer.
이러한 이유에서 본 고안은 미니스커스렌즈를 채택하고 있으며, 반투명층(2)에 맺히는 피투사체의 영상이 전체적으로 균일하고 선명하므로 렌즈의 초검거리만 정확히 맞추면 학습자에게 시각교육의 목적을 훌륭히 달성할 수 있는 것이다.For this reason, the present invention adopts a miniscus lens, and the image of the projected object formed on the semi-transparent layer 2 is uniform and clear as a whole. It is.
