UVA LONGWAVE TORCH FILTERED
UVA Longwave Torch Filtered. This Longwave Filtered Torch is the best and most powerful we have had or seen. The filter cuts out the blue light which comes from the led. This gives a much brighter fluorescence and great for fossicking Fluorescent Minerals. 5 Watts, uses 1 x BRC18650 3000mAh 3.7V li-ion rechargeable battery, online for less than $10. You will receive a battery charger with this order. Portable handheld used for checking out longwave mineral fluorescence and phosphorescence. This Torch has a glass filter which is a UVA Pass filter to block out white light and allow only longwave light at 375 nM to pass. Minerals not included. Battery not included. More than 80% of Fluorescent minerals fluoresce in Short Wave Ultra violet light. UVA light range is 315 nM to 400 nM. Very very powerful!

When we show people Fluorescent minerals for the first time in our shop, we get a lot of OOH WOW and even four letter words sometimes. The view is really mind blowing and better than psychedelic especially the Willemite.
So many uses for this latest technology:
Refrigerant leak detection.
Police forensic investigation.
Fake money detection.
Cat wee detection.
Glue detection for repaired minerals and fossils.
