I picked up a Bio-rad SmartSpec UV-Vis Spectrophotometer on eBay. The SmartSpec uses a Xenon flash lamp and is a much more compact\/similar design than the DU530\/DR4000<\/a> I previously looked at. Of course I decided to pull it apart, and my pictures are below for reference.<\/p>\n\n\n\n

The basic layout is shown below. The PCB looks like a very traditional 1980s\/90s design:<\/p>\n\n\n\n

The lamp sits above the spectrometer block in the metal enclosure, with the cuvette sitting between lamp and the spectrometer:<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

Inside the spectrometer block we see a couple of mirrors and the diffraction mirror:<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

It uses a traditional design, fairly similar to that employed by Ocean optics and other spectrometer makers:<\/p>\n\n\n\n

The light essentially reflects off the diffraction mirror and into a linear CCD. I suspect this is an ILX511, which is pretty common in spectrometers and I’ve played with before<\/a>.<\/p>\n\n\n\n

A few more pictures of other parts of the instrument are below. I’ll add more posts if I do any more work with this device.<\/p>\n\n\n\n
