| + | 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 | ||
| + | |||
| + | |||
| + | ===November, 9, 2010=== | ||
| + | * 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. | ||
| + | |||
| + | |||
| + | ===November, 17, 2010=== | ||
| + | * 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. | ||
