Optical Spectrum Analyzer
-
an optical spectrum analyzer for analyzing short wavelengths from 350nm to 1000 nm. Because it adopts a Fourier spectrum system with a Michelson interferometer, the 8341 can measure the coherence. With its narrow wavelength resolution of 0.01nm * , the 8341 is very effective for the evaluation of not only CD/DVD laser diodes, but also for blue-violet laser diodes. In addition, the built-in He-Ne laser acts as a wavelength reference to ensure a high wavelength measurement accuracy of ±0.01nm * . Finally, with its fast 0.5s * measurement speed, the 8341 is ideal for building into systems for mass production and evaluating temperature characteristics of system components.

The Keysight 10735A Three Axis Interferometer is used in multiple axis applications where linear and angular control of the stage is required. It combines in a single package the functionality of an optical bench with multiple beam benders, beam splitters, and three interferometers. The interferometers split an incoming laser beam into three beams to measure linear distance, pitch and yaw, or linear distance, roll and yaw. Three linear measurements provide the basis for calculating two angular measurements. The inherent beam parallelism ensures that there is essentially no cosine error between the three measurements and also ensures angle accuracy for pitch and yaw measurements.
