4 way Spectrometer Cuvette Holder w/ Ocean Optics 2nd Order Filter Spectroscopy

Description

Up for sale is just what you see in the first picture which is one generic homemade brand 4-way cuvette holder, 2 removable generic brand SMA-905 free beam (non-collimating) lens connectors, and a genuine Ocean Optics second order quartz variable filter.  Besides being a nice low budget 4 way cuvette holder, the variable filter is also a good accessory to have, for example, to help isolate certain wavelengths and/or block possible second order light that might be getting through to your results.  The filter was originally designed by Ocean Optics to go in front of the detectors installed in their spectrometers.  As you pass it through the slot in my cuvette holder, it will block light 200nm to 550nm at different intervals depending on how you pass the filter through. This is a very versatile accessory to have and at under 0, an economical one as well especially considering all the different things it can do.  Thank you.
