The CCD camera is not producing images. Up until now, it was possible to set up an effective laser setup just with “eyeballing it” (no math). Unfortunately, the CCD camera needs to be placed a specific distance from the closest lens, and because we have little experience with the camera, some math needs to happen in order for us to develop a “feel” for the instrument.

f=focus, h_o=hight of object, h_i=hight of image, o=distance from lens to object, i=distance from lens to image

f=focus, o=distance from lens to object, i=distance from lens to image, arrows indicate respective heights (object, image)

\begin{equation M=\frac{-i}{o}=\frac{h_i}{h_o} \end{equation}

where M=magnification

The use of this equation, along with the methods that we have been using in our setups, should produce the desired result: great images that are easy to see and easy to work with.
