High Stability Plane Mirror Interferometer
10706B
Angular Interferometer
The Keysight 10706B High Stability Plane Mirror Interferometer is a dual pass interferometer used for multiple axis applications such as X-Y stages where the measurement mirror may move perpendicular to the measurement axis. This thermally stable optic, an exact functional replacement for the 10706A Plane Mirror Interferometer, reduces thermal measurement drift to 1/12 the value typically achieved by conventional plane mirror interferometers. The unique contribution of the 10706B is its tolerance of angular misalignment of the plane mirror reflector. The 10706A can accept a range of measurement mirror angular alignment changes.

Fourier Transform Optical Spectrum Analyzer, 600 - 1700 nm
OSA202C
-
Thorlabs' Optical Spectrum Analyzers (OSAs) perform highly accurate spectral measurements. Compatible with fiber-coupled and free-space light sources, these compact benchtop instruments suit a wide variety of applications, such as analyzing the spectrum of a telecom signal, resolving the Fabry-Perot modes of a gain chip, and identifying gas absorption lines. Many commonly available OSAs use grating-based monochromators, which have slow acquisition times due to the need to mechanically scan the grating and average out noise at each wavelength. Thorlabs' OSAs acquire the spectrum via a Fourier transform using a scanning Michelson interferometer in a push/pull configuration. This approach dramatically improves the acquisition time, enables a high-precision wavelength meter mode with 7 significant figures and ±1 part-per-million accuracy, and allows the included software to provide robust statistical analysis of the acquired spectra, as explained in the Design tab.
