UV Viewing Cabinet
UV viewing cabinet with long and short wave dual-wavelength
ultraviolet lamp is mainly used to identify and distinguish gem
under stimulated conditions under ultraviolet radiation, or to
understand the characteristics of gems optimal treatment,
recognition of natural and synthetic, or some filling treatment.
This kind of UV cabinets are applications of fluorescence
What is fluorescence technology?
First, let’s take a look at what is fluorescence, and fluorescence
as fluorescence”. It refers to a phenomenon of photoluminescence.
When a certain temperature substance is irradiated with incident
light of a certain wavelength (usually ultraviolet or X-ray), it
absorbs light energy and enters an excited state, and immediately
retreats and emits light longer than the wavelength of the incident
light (usually at a wavelength In the visible light band); and once
the incident light is stopped, the luminescence phenomenon
The outgoing light having this property is called fluorescence.
Secondly, by knowing what is fluorescent, as the name suggests, you
can think of what is fluorescent technology.
Fluorescence technology is the emission of light with a wavelength
greater than the excitation wavelength in a very short time (10-8
seconds) after some substances are excited by light of a certain
wavelength. This kind of light is called fluorescence.
The application of this luminescence in various aspects and related
methods is called a fluorescent technique.
The UV light source lamp features both long and shortwave
ultraviolet bulbs and the cabinet contains a filter to help protect
eyes from ultraviolet rays. The dual short/long wave UV lamp
enables checking for fluorescence; detects dyes, oils and assembled
stones; and helps to distinguish natural stones from synthetics.
