Beam Directing and Reflecting Optics
-
Beam directing and reflecting optics simply reflect, bend or translate the beam, but do not typically modify the polarization, except for polarizing beam splitters. For example, mirrors, cube corners and retroreflectors are attached to objects that move in order to keep the weight down on the moving object (instead of mounting the interferometer on the moving object).

Three Axis Interferometer
10735A
Differential Interferometer
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. Other characteristics include:

Fourier Transform Optical Spectrum Analyzer, 350 - 1100 nm
OSA201C
-
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.

PCI Three-Axis High Performance Laser Board with External Sampling
N1231B
Laser Board
The Keysight N1231B PCI Three-Axis Laser Board with External Sampling is a register based PCI bus board that implements three axes of laser interferometer measurement for position monitoring and closed-loop servo control. There are four external sample inputs along with four data hold inputs that allow easy synchronization with user systems. Several threshold compare registers, with both hardware outputs and interrupt capability, can be used for travel limit and in window or out of window detection functions. The dual mode hardware position outputs, controlled by the hold inputs, provide either a 32-bits/axis parallel interface or a 36-bit multiplexed interface to the 36-bit axis position data at rates up to 20MHz. The user can programmatically access the externally sampled position and velocity data, as well as software sampled position and velocity data, over the PCI bus at rates up to 100kHz (3 axes of position and velocity) or 200kHz (position or velocity only).
