C-SPEC for Windows® (CSW) is a complete software program for use in operating Ocean Optics spectrometers and processing the resultant spectral data.

CSW provides users with powerful acquisition routines including scope modes, individual spectrum acquisition, and overlay acquisition. CSW provides spectral data manipulation routines including mathematical calculations, color calculations, thin film measurements, and various processing routines including an FFT (low pass filter) smoothing routine. All data is saved in ASCII text, for ease in exporting data into other programs. CSW is available from Ancal.
