How can one explain prism dispersion by using nonlinear optics? We all know, that prism disperses white light. We also can obtain mathematical relation between wavelength and deflection angle by using simple linear optics. But I recently heard that the prism itself somehow affects the way light travels through it and that is the question of nonlinear optics. So how can one explain this effect by using nonlinear optics?

Bar optics work with those bottles that have plastic security tops? Having a debate and i am convinced you must be able to get bar optics that work with those bottles that have the tamper proof plastic tops in them.

If you know of optics that do work with the plastic security tops and you have a link that would be most appreciated.

How do you assess the quality of telescope optics? I have Barlow 3x, 50x, 250x optics pieces, and it seems that the 50x is great, the 250x is good, the Barlow + 50x is good, too, but the Barlow + 250x is not that good. I want to determine which optics would be the best to upgrade, or if the problem is the limitations of the scope quality. I wonder if the Barlow's quality is being amplified by the other two optics pieces, so that it really comes out in the 250x, or if I'm simply approaching the limits of the scope itself. How would I assess the quality of their constructions? 5" Celestron reflector scope, FYI Some people talk about poor quality optics that come with the new telescopes. What effect does that have on the observing? Chromatic aberation and edge blurring, I suppose, but are there any other effects? Also, how do you calculate the required aperture for a desired magnification. I saw Jupiter and her moons last night, but I could NOT magnify her clearly and large enough to see the Red Spot. Of course, I hadn't considered that the Red Spot might not always be pointing toward the earth. Obviously, I could have waited for Jupiter to be closer to earth, but I'm a little impulsive and impatient when it comes to viewing things. I was hoping better optics would allow seeing Jupiter's Spot in any clear, dark sky.

Where can I find information on Optics? I am looking for some information on some optics I was given. The box contains a metal slide holder with a built in probe. It also contains a tube with a lens marked EDSCORP on one side and 10 0.25 JAPAN. on the other. There are also two other lenses that are unmarked. I would like any information on these optics or help in finding information. They came from an old science classroom and I have no idea on how old they are. Everything is in excellent condition. There is a little tarnish on the slide holder, and the two smaller lenses show signs of use, but the tube and larger lens very clean.

In optics: Is it possible to translate a focal length of a 35mm lens to a magnification value? For example, if I have a 400mm focal length lens for a 35mm camera, can that translate to a magnification level? Most people that aren't familiar with optics or photography ask me what kind of lens I have.... when I tell them it's a 400mm they just kind of look back with a blank stare. I think they would understand better if I could them it was a 10x or 12x or something like that. I'm a entry level independant photographer and I like talking to people about my work to generate possible intrest in doing work for them, and I just want to be able to put things in laymen's terms for them.
