Use your mini-screwdriver to gently drill holes a couple millimeters deep at the intersection of the markings you made earlier on both wax squares. Place the stilts into the holes. Use this guide to step through the process. For a full list of materials see the Shopping List PDF in the. This guide provides some simple and easy to use design guidelines and formulas for designing, evaluating and comparing various diode array, diffraction grating based spectrometers designs The input to the design process is the wavelength range you want to cover and the optical resolution by which. The slit holder fits snugly into a hole in the side of the spectrometer. Remember that with this spectrometer design the slit and detector are at 90° to each other. Using a plane front surface mirror just after light passes through the slit does result in some light loss (the mirror's reflectivity. A Spectrometer is useful for detecting impurities in water and in other substances, or even just telling us what wavelength something is! If you have a mystery laser and you want to know the wavelength, you grab a laser with a known wavelength, and calibrate the Spectrometer, simply by taking. Drill 2 holes in 2 out of 3 planks These holes should be at equal distances from the sides, roughly centered with respect to the height and wide enough away from each other so that a razor easely fits between them. We recommend disposable gloves and hexagon socket screws to prevent scratches and fingerprints.
