THORLABS OSA305 Optical Spectrum Analyzers (1,0 - 5,6 µm (10 000 - 1786 cm^-1 ), 1.9 GHz Resolution)

Wavelength Range(a): 1,0 - 5,6 µm (10 000 - 1786 cm^-1 )

Level Sensitivity(c,d): -65 dBm/nm (1.0 - 1.5 µm). -70 dBm/nm (1.5 - 5.6 µm)

Free-Space Window Material: Uncoated ZnSe

Operating Temperature: 10°C to 40°C

(a) Limited by Bandwidth of Detectors and Optics

(b) Specified in high-temperature mode. In low-temperature mode, the wavelength range is 1.0 - 2.5 µm.

(c) Minimum detectable power per nanometer using Zero Fill = 0 and the highest resolution and sensitivity settings.

(d) See Graphs in manual

(e) In the 350 - 500 nm range, the OSA201C will easily detect lasers and other narrowband sources, but broadband sources may not have sufficient power spectral density to be detected.

(f) Specified in low-temperature mode over 1.0 - 2.5 µm. In high-temperature mode, the level sensitivity is -65 dBm/nm over 1.0 - 2.6 µm.
