Design goals

Design Goals

  • The goal was to design as precision optical platform that would have:

    • Severalhundred μm range in the X-Y plane,

    • Stability when subjected to normal laboratory conditions,

    • Around μm resolution,

    • Have a small package size compared to what is commercially available.

    • Be independent of orientation with respect to the gravitational field.

  • In addition several other factors arose in the design process. These factors became prominent when I determined to make a prototype for demonstration in class and at work. These factors were:

    • Simplicity of design

    • Machinability

      • Since I needed to make a prototype I needed to keep the materials common and easy to machine with the facilities that were available.

    • Low parts count

    • The ability to modify the design easily for different experimental requirements.
