  • Wavelength Tracker

    10717A - Keysight Technologies

    The Keysight 10717A Wavelength Tracker tracks changes in the air's index of refraction to optically compensate for environmental changes. It uses one axis of a laser measurement system to report wavelength of light changes, not changes in position. It is used to correct displacement values reported by other measurement axes in the system, hence improving measurement accuracy. It provides a higher degree of accuracy than environmental sensors such as the 10751C and 10751D Air Sensors.

  • Fourier Transform Optical Spectrum Analyzer, 350 - 1100 nm

    OSA201C - Thorlabs, Inc.

    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.

  • Panoramic Boroscope

    H Series - Titan Tool Supply, Inc.

    The H Series Rigid Borescope is a Borescope with a Revolving Prism that allows for a 140 Degree total Field of View instantly from Straight Forward to 110 Degree to the rear. Totally eliminated are the different Borescopes each with their own viewing angle or sleeves with similar limitations.One unit viewed directly or connected to Video allows 100 percent examination of any cavity without any limitations.The rotating Prism located in the front of the rigid Borescope swings over a 95 Degree arc, to allow for this major accomplishment with a 45 Degree Field of View within its arc. This rotating capability necessitates a slightly larger head diameter than the body of the Multiscope.The H Series Rigid Borescope uses a Fiber Optic Illumination, which necessitates the purchase of a fiber optic bundle to connect to a Halogen Light Source either the FOI-150 150 Watt Halogen.
