A compact UV flashlight for mineral collectors.
This model combines three useful wavelengths in one device:
• 395 nm - common longwave UV. • 365 nm - cleaner fluorescence with less visible purple light. • 254 nm - shortwave UV-C, which is much less common in portable flashlights.
Shortwave UV is especially interesting for collectors, because some minerals show their best fluorescence only under 254 nm.
Several of my customers have already received this flashlight and are very happy with it.
Available by direct message.
Safety note: 254 nm UV-C can damage eyes and skin. Use proper UV protection and never shine it at people or animals.
