Figure Strong Magnifier with Light

This magnifier I have chosen because it should be a relief for my work. So far I use already an achromatic 10x magnifying glass with plastic lenses and external light source.
The image quality and resolution are compared much better. The LEDs are arranged in a ring and give thanks to the frosted cover an equally neutral light.
Unfortunately, the manufacturer does not specify a waveband for these UV LEDs, only a 'long-wavelength range', which, compared with its fluorescent tubes, must be at 366-380 nm. Now I use dyes having an absorption maximum of 350 nm and more than a slight shimmer is not emitted. Consequently, the maximum intensity would have to be somewhere at 380 nm. For the bill check the UV LED is also useless, because except for a few filaments nothing can be seen.
Should there eventually be a successor of the magnifying glass, I would like to see the function of the lights, only one half of the ring, for a drop shadow, so you can detect surface defects more easily.
Taken all together, not a bad magnifying glass, but perhaps only for stamp collectors, when then band the right.
