Hi! I´m a dentist and I own a couple of surgical loupes... I´m a DIYer for the fun of it, but I´ve got a limited knowledge in physics... I´d like to adapt a CCD (I´ve got one from a webcam) to the eyepiece of my loupe´s ocular... So I can take pictures or even film what I´m seeing so I can show my client what I´m seeing in realtime. There´s some DIY WIFI camera kit on ebay, so this is where probably I´ll follow after solving the optics problem...... Here´s what I´ve done so far, and what I don´t understand... and maybe some of you could light me a solution... My loupe´s ocular is a small telescope with prisms inside to correct the position of the image, like a binocular. And I can adjust the focus and distance from the subject by making the eyepiece farther or shorter away (rotating it). So the farther I focus, the smaller the magnification is, the closer I focus, the higher the magnification is. My loupe has 4.5x magnification. The weird thing (to me, of course, an ignorant in optics...) is that... If I place the disassembled webcam CCD in front of my eyepiece...the way I would in front of my eye... the magnification is not the same as it´s in my eyes... In fact, the distance from the subject gets super-short and the magnification increases a lot! What I did, for testing so far, is to remove the eyepiece from the ocular´s barrel, and I put then the CCD right in front of the prisms, where the eyepiece would be attached to. When I did this, the magnification is similar from what I see in my eye, and it seems to focus a little shorter than it would be with the eyepiece and looking through it with my eyes. But by doing so, I loose the ability to adjust the focus distance and magnification. In fact I don´t. If I move the ccd farther from the prisms (just a mm or so), the focus distance decreases more and the magnification increases.... I´d like to do the opposite... be able to increase or decrease a little bit the focus distance, to match the exact distance my eyes sees through the lens... so the ccd would see exactly what I see and at the same distance. But I can´t increase the focusing distance.. the CCD is already almost touching the prisms... I can´t reduce the size anymore of the loupe´s barrel... So.. is there a solution to this? Is there an... alternative eyepiece I could use to couple with my loupe (by removing the loupe´s original eyepiece) that would focus and work normally with the CCD? I need also a IR cut filter (removed the webcams lens, lost the IR filter) , but I think it´s and easier task to adapt... English is not my first language, so...sorry if all this got bad explained.... Thanks a lot!
