New JDEPC-05 camera mount for the DAV5 V3 spectrometer, redesigned to accomodate a 25mm Schott glass filter for blocking stray light at the detector;

Transmission (including surface reflections) is plotted as a function of wavelength to the right. The region shaded in blue represents the range over which this filter is transmissive. At wavelengths shorter than the cut-on wavelength, the filter blocks the light.
