<p>Hello all, I am thinking of making my own lens, yes my own lens and not as simple as pinhole lens or something.<br>
I have researched some and find some videos as well showing how hard (or easy) process it is to make a lens. Mot looking for top notch quality anyway closer to deal itself...</p>
<p>Dos anyone know what king of lenses do microscope have ? ( additive, positive, ...) It is definitely combination of lenses with different specifications. I am interested in this because the easiest way for telephoto optics is Galileo telescope (upside down telescope) in the way it works you have 2 lenses with different magnification : one small, for example 2x and other big, for example 6x then you combine then in different distances, I am thinking of using the small one from a microscope, may sound ridiculous but difference in magnification and tube length is the main thing that affects the resulting focal length and so on, other ways as well...<br>
So, do anyone have experience with building home made telephoto lenses ? Not talking about pinhole, holga or macro tubes.<br>
Any info will be useful so as this is the first time I will be trying something like this.</p>
