This Ultraviolet display was made for the Open day in 2014.

It is half of a larger display. The other half is for radioactive specimens. There is an acrylic cover and a flip up signing board. There is switchable internal lighting, fan cooling and a shelf at the rear for the various predominantly 12 V plug pack supplies.

All components are mounted on a perforated board with simple self tapping screws. This makes removal or changing position of a part of the display easy.  I could make the display more dynamic by rotating the items on a platter past the UV source.

The main UV light is a 10 W LED which has some heatsinking requirements. I later added an upward facing 3 W UV LED to show fluorescence of external items.

The ultraviolet display fluorescent items are:

• fluorescein in bottle
• tonic water in unopened bottle,
• Rhodamine D (orange container),
• uranium marble,
• fluorescent scorpion (faded),
• activated zinc sulphide (yellow plastic bag),
• wernerite (orange rock),
• fluorescent plastic rod,
• fluoro acrylic sheet,
• red nightclub bangle,
• strontium aluminate with 2% europium activation for exotica (pink bag).
