First of all: 365/395 refers to the wavelength (in nm). Generally speaking, the shorter the wavelength, the better the penetration. The light emitted at 365nm basically does not contain purple, which does not affect the judgment. The purple at 395nm is very strong, which sometimes affects the judgment.

1) 365nm violet light (generally refers to the wavelength of 360-365NM)

Ultraviolet LEDs in 365nm band are relatively expensive (for ultraviolet rays, the shorter the wavelength, the more expensive it is).

365nm: Visible light is only very weak, and ultraviolet lamp beads with 365 quasi-wavelength can hardly see purple light, because imported chips do not have purple light, and can be used in almost all kinds of products to identify authenticity (fine inspection, flaw detection (industrial use, accurate damage identification of parts), and fluid trace detection (.

In other special occasions, when 365nm is specified, 365nm must be used.

2)375 nm violet light (generally 370 ~ 380 nm)

375nm ultraviolet light is basically suitable for all kinds of identification. Scope of application: foreign currency, jade, jadeite, invoices, etc. Only purplish visible light, the effect is worse than 365NM!

The cured UV glue will be better than 395. In fluorescent printing, the cost performance of 375 nm is particularly high.

3)395 nm violet light (generally 395 ~ 405 nm)

Scope of application: (UV ink curing, glue curing; Fishing lamp, indoor mosquito repellent lamp; Fluorescence reflection of special substances (taking photos of scorpions, catching scorpions, checking banknotes, etc.). ); UV nail lamp, purple jewelry lamp;

Essence: ultraviolet lamp irradiation is a method to check the glue injection.

Summary: Go to 365 if you have money.
