I need help testing so I thought this might be a nice way to help some one out. I will give a 6 inch by .8 inch quartz blank that is flat on each side and clear to the person that can do the best testing of it. So if you are willing to test it and post your findings good and bad and you have the ability to test it I will send it to you. You will get to keep it after testing. No strings and I pay for shipping. So please tell me what you are going to do to test it and why you can do the best job. I will pick a winner with the help of all of the people interested in this in 10 days. If you have anything to add to make this as fair and unbiased as possible please let me know. I have posted this on CN as well and was able to define this a bit more.
I have had some good comments so far; Let me add a few things. The blank is flat on each side like a window but I do not think it is flat like a secondary mirror but could be made like that. I have found it to be .0005 or better using a micrometer so it should be flat enough for testing. What I would like to know is how good is the quartz to make into a lens or use for optical glass. Some tests I have know of are shadow graph method, Polariscope testing, interferometer test, and Zygo. I do not know how optical flat the quartz will be but I think it might be very good for use as transmission quality and the person that can do this kind of testing will get this blank to keep. I am very happy at how much every one wants to help out for the good of everyone.
