Two Axis Differential Interferometer
10721A
The Keysight 10721A Two Axis Differential Interferometer, when used in multiple axis applications, simultaneously makes two differential measurements linear and angular (yaw) displacement. Both measurements reference external mirror mounted to an object such as a column or inspection tool. The 10721A provides high immunity to unwanted interferometer displacement, such as thermal expansion. It is a modular, compact design with monolithic optics for maximized mechanical stability. Use of a small 3 mm beam helps decrease Abb offset error. The 10721A is similar to the 10719A Single Axis Differential Interferometer, except that it provides an additional measurement axis.

Series Voltage References
Analog Devices offers a broad line of series voltage references with low dropout, low power, and excellent line regulation. These devices are voltage references that are functionally similar to a three-terminal regulator. Some series voltage references are designed to also operate in shunt mode by biasing the output pin and leaving the input pin open circuit. Series mode voltage references have the advantage that they draw only load and quiescent current from the input supply.
