Dog and Cat pee/urine detection at this 365nm wavelength.
Dry urine will show easily on dark surfaces, fresh urine has a bluish look.
If you want maximum effect from “black light” reactive items, 365nm is the proper wavelength for this.
365nm UV flashlights will activate faint traces in fluorescent objects (without the visible purple seen in a 400nm UV flashlight).
Therefore 365nm is more suited to close-up work and faint detection.
365nm wavelength LED produce a near pure UV output which is the optimum frequency for UV fluorescence.
You will see far more detail and in a greater range of colours in gemstones than any other wavelength.
365nM UV generate less unwanted “Interference Light” and they may naturally appear weaker or more white compared to visible purple 400nM versions.
This can be misleading and should not be misinterpreted.
General rule of thumb is that the more visible UV light you see the less effective it will be for detailed, faint detection work.
This is how UV wavelengths usually works:
230~400 nm: Optical sensors, various instrumentation
240~280 nm: Disinfection, decontamination of surfaces and water (DNA absorption has a peak at 260 nm)
200~400 nm: Forensic analysis, drug detection
270~360 nm: Protein analysis, DNA sequencing, drug discovery
280~400 nm: Medical imaging of cells
300~320 nm: Light therapy in medicine
300~365 nm: Curing of polymers and printer inks
300~400 nm: Solid-state lighting
350~370 nm: Bug zappers (flies are most attracted to light at 365 nm).
Uses for the 365nM wavelength torch:
faint traces of fungus
leak detection in refrigerants
portable EPROM eraser
detecting head lice eggs
water pollution detection
chemical probe testing, chemistry
money checking, credit card checking
Antique glass (uranium glass, vasceline glass)
Forged document detection
A/C coolant leak detection (using dye)
Hotel room inspection
Mineral Hunting (diamonds, etc.)
Salmonella and Shigella bacteria detection
Contaminate inspection (clean environment)
Drivers licence UV markings
Dye penetrant inspection (NDI/NDT)
Magnetic surface analysis
ATTENTION – CAUTION
Eye damage guaranteed from careless use.These LEDs are manufactured to be almost invisible to the naked eye.
It is made for a specific purpose and should not be used by children or people unauthorised by you the tradesman.
Invisible UV is particularly dangerous to the human eye because it cannot detect that damage is being done.
