Two Axis Differential Interferometer
10721A
Differential Interferometer
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.

40Gb/s DQPSK Receiver
-
The integrated DQPSK receiver incorporates an optical phase demodulator (delay-line interferometer or DLI) with 2 pairs of balanced photo-diodes and 2 linear TIAs into a single butterfly package. Compared with the currently available discrete solution in which a separate DLI and a separate receiver are used, the integrated DQPSK receiver eliminates labor intensive fiber routing and coupling (between the DLI and the balanced receiver) as well as the skew control. Moreover, the integrated DQPSK receiver offers a smaller footprint suitable for today’s demanding high speed transponder applications.

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.

Portable Connector End Face Geometry Interferometer
-
Thorlabs’ Vytran® Connect-Chek® Interferometer automatically and precisely measures radius of curvature, apex offset of polish, and fiber undercut or protrusion on any PC or APC, single-fiber connector. The CC6000 interferometer uses a non-contact tilted-phase-analysis technique for fast, reliable measurements of connector end faces. This compact interferometer has a carrying handle and must be attached to a desktop or laptop computer (not included) with a standard USB 2.0 port for operation. The included CC6000 software, which is used to control the interferometer, can be installed on a computer with the minimum requirements in the table below. Designed for use in both the factory and the field, this interferometer provides crucial quality information needed to assure long-term performance of fiber optic connectors. One CC250P Mount for Ø2.50 mm PC Connectors and one RT250P Reference Tool for calibrating the CC250P mount are included with the CC6000 interferometer; mounts and reference tools that enable measurement of other PC or APC, single-fiber connectors are available separately below. When used with an appropriate mount for APC connectors, the CC6000 interferometer is also capable of measuring the APC angle and key error.

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).

Differential Interferometer
The Keysight 10715A Differential Interferometer performs differential measurements between the supplied reference mirror and a measurement plane mirror. It provides exceptional long term stability. The 10715A minimizes dead path, and, because the entire optical path through the interferometer is common mode, it eliminates thermal drift in measurements. The resolution of the measurement is twice that of a linear or single-beam interferometer.
