What is a CD spectrometer?

A Circular Dichroism (CD) spectrometer (also referred to as a spectrophotometer, spectropolarimeter or a circular dichrograph) is a highly specialized variation of an absorbance spectrophotometer.

How do you cut a CD spectroscope tube?

Use a saw to cut the tube at an angle along the curved line on the cutting guide (see below). The cut will make the CD tilt at an angle approximately 30 degrees from the end of the tube. Use a razor knife to cut the rectangular viewing hole—the black square on the cutting guide. You can remove the cutting guide now (see below).

How can I make a CD spectrometer from a CD?

A simple spectrometer can be built from a CD and a box. Cut a slit on one side of the box. Place the CD on the other side with about 60 degree angle. Look down into the openning on the box. The slit should not be too wide, otherwise the spectrum lines will be blurred. It should not be too narrow either, otherwise the spectrum is too dim.

How does light enter a spectroscope through a CD?

Light will enter your spectroscope through a small slit (the diffraction grating), reflect off the CD, and be seen through the viewing tube. The CD will help to ensure that the three elements line up correctly. Step 1: Begin by making a hole for the viewing tube.

How do you make a spectroscope from a cracker box?

If you use a cereal box or a cracker box, make your cuts just below the nutritional information. Connect these two diagonal cuts with a horizontal cut along the edge of the box. This slot will hold your CD. Make a spectroscope with these materials. 2. Make a viewing window on the top of the box (above the CD).
