Thorlabs OSA202C Optical Spectrum Analysers (OSA) is a general-purpose spectrum analyzer for optical research, allowing fast and precise measurements over a wide spectral range. The operating wavelength for OSA202C is 600-1700 nm. The OSA instrument is versatile enough to analyze broadband optical signals, resolve the Fabry-Perot modes of a gain chip, and identify gas absorption lines in a spectral. It has an FC/PC-style optical fiber input and a free-space input. After the input light is collimated, a beamsplitter divides the optical signal into two separate branches. The path length difference between the two branches is varied up to a maximum of 40 mm. The instrument is designed for measurements of continuous wave (CW) light sources but pulsed light can also be used.
