Open source DIY kit

This documentation describes how to make a blue LED (470nm) transilluminator for DNA imaging. There are several kit sizes available:

• Mini transilluminator kit (IMG-04-01): 6 cm x 7cm viewing area, 9x8 led array

• Midi transilluminator kit (IMG-04-02): 7 cm x 14 cm viewing area, 9x18 led array

• Large transilluminator kit (IMG-04-03): 14 cm x 14 cm viewing area, 18x18 led array

Each blue LED transilluminator kit comes with the following parts:

• Electronics: LED array PCB, set of blue LEDs, switch, DC Jack and resistors

• Hardware: Standoffs, screws and a mini-screwdriver for easy assembly

• Enclosure and filters: Laset cut acrylics including the black enclosure, diffuser, amber and blue filters
