Medical 420 fluorescent uv

Key Attributes.

My plant production and management of medical 420nm UV powder, quality assurance, welcome to consult the discussion. New light-emitting function-specific fluorescent phosphor h. diazo copy Light peak: 420nm, light color: blue-violet Light peak: 395nm, light color: blue-violet Special ultraviolet light production copier source. UV and near UV phosphor UV and near UV phosphor is excited at wavelengths shorter UV wavelengths longer issued under the ultraviolet light-emitting materials. If issued under UV excitation at 280-400 253.7nm ultraviolet phosphor is called ultraviolet or UV lamp phosphor phosphor, also called black light powder. Near the wavelength 400-420nm near UV or violet phosphors collectively phosphor. Divided into treatment by use of UV-phosphor fluorescent lamp and UV lamp phosphor moth. Ultraviolet wavelength range 300-400nm can be used to treat psoriasis and vitiligo, but also trap and kill mosquitoes and insects. Health lamp phosphors in the wavelength range between 280-350nm, helps the body metabolism. Near-ultraviolet fluorescent lamp phosphors for diazo copying, copying paper which can promote diazonium salt decomposition.
