Mathew's Assembly Run

  • 3 injection molded plastic (ABS) parts
  • 2 short screws
  • 2 long screws
  • 1 short black paper liner (5cm x 4cm)
  • 1 long black paper liner (5cm x 8cm)
  • 6 5cm lengths of double-sided tape
  • 1 5cm black foam tape
  • diffraction grating (5cm x 4.4cm) *protective film I did without-- this extra step increases the chances of damaging the grating in order to protect it.
  • precision printed slit
  • jewelers screwdriver
  • razor blade

Adhesive options

Here's a list of other adhesives and tape strips which may be helpful in assembling and mounting the spectrometer. Some may be shipped in the kits:

  • Tape strips are sold for costumes and wigs: http://www.amazon.com/Bonding-Double-Tape-Walker-Straight/dp/B00D7LA162/
  • 3M's super strong 300LSE in letter sheets, ~$12 each: http://www.amazon.com/9474LE-super-strong-double-sided-adhesive-transfer/dp/B00CCGK31G/ ** these are an excellent option. 3M sells 24x36" sheets somewhere. we can save users any trimming through cutting to 6mm wide-- the width of the edges of the mountplate. one sheet = 300 30cm strips 6mm wide, giving each user 6 5cm pieces they can cut to length with their razor. Then there's no tape trimming to do when attaching.
  • Scrapbooking tape strips: http://www.amazon.com/Double-sided-adhesive-mounts-12-pack/dp/B00D5WDZXO/ (hard to find but good size -- big lots available on ebay: http://www.ebay.com/itm/New-72-Packs-Scrapbook-Double-Sided-Adhesive-Strips-/321157403796 is 3600 strips for $65, or 2c per strip)
