The temperature stabilization and temperature measurement of a Kösters interferometer

Measurement Science and Technology, 2005
In this work, the mechanical design, optical setup and temperature measurement system of a Kosters interferometer are described for the length measurements of long gauge blocks. The temperature variation of 9 mK at 15 °C and 2 mK at 20 °C was measured inside the interferometric chamber using the six air and four surface thermistors.
