This week I have been working on the refurbishment of the excimer laser. I have completed the online safety course required by the university and will be taking an eye exam shortly. I have also established a contact with Coherent Inc. technician Jeff Edberg. Jeff worked on older EMG 101 MSC before the company was bought out by Coherent Inc. He recommended taking the laser head off and checking a circulating fan for the laser tube. If the motor doesn’t turn then the project would most likely be canceled because it is impossible to find parts. Thursday, I took off the cover of the excimer laser and was able to verify that the motor is working properly. We are now ready to move the laser down to Dr. Barry Wells’ laboratory which I visited this Monday. The lab has the proper exhaust, power supply and water system we will need and all we are waiting for is a table from Dave Perry.

The wiki page has been updated regarding the progress of the laser and of the fiber splicing possibilities. Lastly, I have contacted various camera repair companies in a long shot attempt to gain some information on the Casio ex-f1. I actually received a promising email from Stan Tamarkin saying that he knows the president of Casio. With any luck, he will be able to give us some new information on the layout of the lens system.

Progress, week of 11/12/09
This week, I have made two major steps forwards. Most importantly, I have completely redone all of my flawed lens equations. I have rewritten all of the code in my Excel sheets to correct problems with the equations. Also, the new equations generate the appropriate object distance given that the final image falls on the reciever. From this, the magnification of the object as it falls on the reciever can be calculated as well.
Secondly, I have studied the effects of the aperture size and f-stop on the final image. While I am unsure if I will be able to add a variable aperture to my charts and graph without gross simplifications, I believe I will be able to calculate the intensity of the image given the size and position of the aperture. However, if we assume that the aperture is fixed somewhere between the second and third lenses in the lens assembly, I may be able to add it to the light paths. Because a changing aperture only affects the intensity of the light falling on the reciever, it might not be important to add it to the light path diagram. For next week's meeting, I hope to have all the lens equations completely finalized and completed.
