Please post these here:

===December 1, 2010===
  * Optics that were ordered came in
  * Tested optics with laser pointer
  * Mounted optics in proper mounts
  * Found focal length of lens

===October, 20, 2010===
  * Found that we needed a zero degree shift mirror and ninety degree shift mirror to achieve optimal beam geometry
  * Looked up prices on ebay for mirrors
  * Looked up lenses for CO2 lasers on ebay and found that ZnSe is most prevalent
  * Found prices for ZnSe lens on ebay
  * Talked to Sinisa regarding a standardized tool mount for CNC machines
  * Found prices for CNC mount on ebay
  * Found prices for optics mount on ebay
  * Make model of [[Laser Beam Redirection|setup]] on AutoCAD
  * Discovered that preconfigured setups for the optics for a CO2 laser are available on ebay and that they are also cheaper than assembling the setup by ourselves

  * Searched for adjustable mirror mounts for co2 laser
  * Found out that quarter wave is the same as 90 degree phase shift, which we mentioned before as circularly polarizing light.
  * Found a laser kit with co2 laser lens,laser reflectors, laser mirrors, and laser head with air nozzle for $200.
  * Used Noah's suggestion of mirror mount with 1/4 wave first mirror for $69. This will give us one mirror that has a 90 degree phase shift.
  * Needed one more mirror, cheaper to buy 3 for $20 from alibaba.com.
  * E-mailed distributor for dimensions on mirror mounts and laser head, and Yudi will try calling the business number later today.

  * Made the check list for all the parts that need to be ordered with price. 
  * Made an arlternative list of parts with price as a back up.
  * Sent Professor Lima the list.


===November, 20, 2010===
  * Made another alternative parts list that included mirror mounts, quantities, and specified different optics.
  * Uploaded price list from alibaba.com, and an alternate price and parts list. 
  * Updated optics subsystem page to better reflect our current situation.
  * 1/4 wave is not the same as 90 degree phase shift.


===November, 23, 2010===
  * Made sure that the mirrors and mounts had been ordered from alibab.com.
  * Got the actual costs of all the parts needed.
  * The alternative list will not be needed anymore.
  * Talked about the things that should be covered in the paper.
