Unformatted text preview: MEMORANDUM Date: February 19, 2006 From: Grant Corley, Andrew Godbehere, Albert Ho Subject: Progress Report on Temperature Controllers Summary This project’s goal is to develop an inexpensive method for maintaining the temperature of the Alexandrite laser developed by A&EP Lasers to a specified temperature between 30 and 100 degrees Celsius. We are currently experimenting with inexpensive thermistors that can be used in a temperature controller to maintain a temperature to an accuracy of ±3 degrees Celsius. To date, we have collected and analyzed calibration data for the thermistor. The remaining task in the project is to design and test the prototype temperature controller design, but we may be unable to meet the project specifications because of the poor quality of the lab equipment. Project Description This project’s goal is to develop an inexpensive method for maintaining the temperature of the Alexandrite laser developed by A&EP Lasers Inc. to a specified temperature between 30 and 100 degrees Celsius. A thermistor, an inexpensive semiconductor device whose resistance varies as a function of temperature, is being tested in a temperature...
