fresnel

The video above is a test vedio using the our CPV model. The video below is F= 700 800 pies developed recently.

In this time, let me show you a lighting module equipment for inspecting flaw before shipping large glass substrates. We have a lot of experience which developed and manufactured beam projectors like Sayview, Ecoview etc in the past. The core of this work was adjusting uniformity. The total area is 15% uniformity of light illuminating an area of

  We received a request asking to changing the shape of projected light and beam angle by applying lens to metalhalide light source. 텍스트 또는 웹사이트 주소를 입력하거나 문서를 번역하세요. 취소 metalhallaiteugwang-won-e lenjeuleul jeog-yonghayeo bimgaggwa tusadoeneun bich-ui moyang-eul byeongyeonghaedallaneun uiloega deul-eowassseubnida.     You can check the reduced beam angle even by the naked eye when

We received a request. A client asked us to modify beam angle of the multi-array product arranged a lot of LED. He previously equipped individual lenses to each LED, then he faced a problem about product reliability and workability in processing so wanted to change that way.       It would take a long time to

We received a request. A client want us to make a enclosure that enlarge the size of image from Ø10mm to about 1m, 2~3m in distance. The principle is the same as the OHP projector that was widely used in schools and churches in the past. It outspreads the light from its source to image

Let me show you that fresnel lens is used in art. This photo was taken by someone not us. ** Source : http://hajung0923.blog.me/220012892678 The top of this picture is the Fresnel lens which DIYPRO is focusing on. I admired how this wonderful direction and trajectory were possible although I know about lenses well.. I feel that knowing technology is one thing and making it art

You can see the larger area through wide fresnel lens more easily and conveniently. We use the lens that its specification is same as that of Terasaki Big Eye. ** Purposes more effienct for precision crafted easy to adjust the lens angle convenient when you working with both hands The removable lens Name Large Stand Magnifiers Magnification 2.0X
