NEWTON, N.J., April 23, 2012 — Thorlabs has released the first product in a planned line of optical spectrum analyzers (OSAs). While many commonly available models are grating-based monochromators, this version uses a Fourier transform OSA with a scanning Michelson interferometer configuration. The result is a device that operates as both a full-featured OSA and a high-precision wavelength meter. It features a 1000- to 2500-nm wavelength measurement range, spectral resolution of 7.5 GHz when used as an OSA, and wavelength meter resolution of 0.2 pm. The input aperture accepts FC/PC-terminated fibers, suitable for interfacing with the company’s tunable laser kits, pigtailed laser diodes and fiber collimators. The instrument is supplied with a laptop computer preloaded with a software package for acquiring, inspecting, manipulating and analyzing spectra and interferograms. A customizable graphical user interface makes it easy to identify spectral features, to measure optical output power over a wavelength range, and to track many other parameters as a function of time. The software provides drivers and libraries to operate the OSA using C, C++, Java or other programming languages, and a set of LabView routines is provided to assist with developing custom applications in that dynamic environment.
