a High-Speed USB 3.0 port. It is equipped with an FC/PC fiber input receptacle
and a free-space input window for collimated beams up to Ø10 mm; however,
special designs with other input receptacles are available on request. The
frequency-locked reference laser can be accessed via the FC/APC connector on
the front panel. The instrument is designed for measurements of continuous-wave
(CW) light sources but works in some applications where pulsed light is used.

Software

The Redstone OSA305 is shipped with the software package pre-installed on the
laptop computer that is included with the purchase of this instrument. The software
has a customizable GUI for acquiring, inspecting, manipulating, and analyzing
spectra and interferograms. The software makes it easy to locate and track
spectral peaks or valleys, measure the optical input power over any wavelength
range, calculate an absorption spectrum in real-time, or track a large number of
parameters over time.
For usage with other computers the software is downloadable from the webpage.
