Summary
Shortwave UV light in a 'safe' box (to stop the light burning your eyes and a longwave UV light and an ordinary white light.

It can also be used for steralising small items of jewellery to make them safe from covid - but please read the explanation first.
Can be switched to UV longwave, UV shortwave, or white light. To see the reaction under these three different lights it can also be set to 'cycle' automatically through all the modes.
Can be powered by batteries or mains.
INSTRUCTIONS: place your item on the table, place the UV lightbox over the top .
Read all about how UV light works and what it will detect (fascinating article!)

QUESTIONS & ANSWERS
Ask a Question-
Do I need protective glasses when use the uv safe box?
No you don't need protective glasses.
Switch it to white light, turn it upside down, you can see the LEDs.
Switch it to Longwave UV, turn it upside down, you can see the LEDs.
Switch it to Shortwave UV, turn it upside down, you CANNOT see the LEDs because they are set inside the edge of the unit and reflect off a mirror. -
What are the internal dimensions? How is it to be used as a practical gem/jewellery UV tester?
Maximum (realistic) sample size: 35 X 20mm. You can certainly fit larger objects but if they are too large they will block the light, this is designed for gemstones or very small mineral samples ...or stamps.
We can’t help you with “using UV light as a diagnostic tool in gemstone identification” – that is more complicated, you will need to research it yourself. Ideally you need to go on a practical course in gemmology to view different type of fluorescence and phosphorescence in gemstones under different wavelengths. -
Please can you advise if the wavelengths are 254nm and 365nm?
Yes, correct, as stated in the product description.
