The lenses is 5mm wide (diameter=5mm), and it has a focal length of 6mm. Here' an example of the lenses I'm talking about: here. I know about the formulas M=hi/h0=-di/d0 and the lens equation, but I'm not quite sure how I can calculate the precise magnification.

A Mainster lens has 58% more working field of view and 3% more magnification than a Goldmann lens. For Goldmann, Krieger, Panfundoscope, and Mainster lenses, respectively, retinal spot size is 8%, 53%, 41%, and 5% greater than photo-coagulator spot size settings. The field of view of each lens is increased in myopic and decreased in hyperopic ...

Answer: Laser Lenses include a range of lens types including PCX Lenses, Aspheric Lenses, Cylinder Lenses, or Laser Generator Lenses. Laser Lenses are designed to focus light in several different ways depending on the lens type, such as focusing down to a point, a line, or a ring.

Introduction. It is important to know the magnification factors for condensing slit-lamp lenses because this allows: accurate measurements to be made when using a particular lens on slit lamp. accurate predictions of the laser spot size created by the lens when it is used for laser. Image magnification = size of image / size of object = 1 ...

Thus, I suspected that I might be able to use a simple laser pointer to cast a collimated image of an EM grid through a homemade lens and then measure the projected image to determine the magnification of the lens. The diagram below shows the general idea behind this strategy. 2. BUILDING AN IMAGING APPARATUS

Seeing this diagram might help you understand why a lens will seemingly increase the amount of power a laser puts out. Its clear that it doesnt actually increase the amount power it just focuses it at a specific point, this is one drawback to this burning method because your laser wont behave like a normal laser point after this because past the focal point your beam will diverge, acting more ...
