The OSA305 from Thorlabs Inc is an Optical Spectrum Analyzer that can measure wavelengths from 1 to 5.6 µm. It has an optical sensitivity range of -75 to -65 dBm/nm with a dynamic range of 40 dB. This spectrum analyzer has a spectral accuracy of ±0.2 ppm and spectral precision of 0.2 ppm. It has a power level accuracy of ±0.4 dB and polarization dependence of ±0.1 dB. This spectrum analyzer supports FC/APC and FC/PC optical fiber connectors.
The OSA305 has multidetector operation for a broad operating range and a trigger input for external synchronization. It has built-in hose connections for optical purging and a free-space input port with four 4 - 40 taps for 60 mm cage system compatibility. This spectrum analyzer requires an AC supply of 100 - 240 V and consumes up to 250 W of power. It is available in a benchtop module that measures 541 x 224 x 533 mm and is ideal for optical research, measurements, instrumentation, and production applications.
