Application of Jade Identification Flashlight
Appreciation of jadeite Under the illumination of a jade flashlight, crystal-like substances such as monosodium glutamate and salt may appear in jadeite. If you can’t see such a substance under the light, there may be two situations: this item is not real jade, it may be glass; It may be a sky-high jadeite. The color of good jade is generally evenly distributed, and the internal lines of the jade cannot be seen, but after dyeing, there is a color difference between the crystal grain jade and the gap, and it appears as a spider web under the light of a [...]

Ultraviolet definition
? Ultraviolet light is an electromagnetic wave with a wavelength between 10nm and 400nm. It belongs to the invisible light other than the seven-color light (Red orange yellow green cyan blue purple) visible to the human eye. From the wave-particle duality of light, ultraviolet light is shorter than visible light because of its wavelength, Its penetration in the propagation process is very weak, but it causes photon energy to be greater than visible light, and it is easier to trigger a series of photochemical reactions and electronic transitions after irradiating substances. The application of ultraviolet rays is based on the [...]
UVA application
Excite fluorescent substances to produce fluorescent reactions When ultraviolet rays hit certain substances, these substances emit visible light of various colors and different intensities, and when the light source stops irradiating, this light disappears. These substances that emit fluorescence are fluorescent substances. Fluorescent substances are widely present around our lives, such as fluorescent agents (whitening agents), fluorescent minerals, petroleum, biological oils and other fatty compounds, as well as some organic macromolecular compounds (vitamins, amino acids), etc., so we can use the fluorescent reaction in some applications.
Plant illumination lamp
Although the light source in the ultraviolet band cannot participate in the photosynthesis of plants. But it can cause plants to have special morphology, with short stems, shrunk leaf surfaces, developed furry, increased accumulation, increased chlorophyll, and anthocyanins in the stems and leaves, and the colors are particularly gorgeous. In addition, ultraviolet rays are harmful to plant microorganisms. Use lamps that can provide low-dose ultraviolet rays to kill pathogens without harming plants. For example, certain bacteria can cause plant diseases such as wilt and rust, and the technology has also been proven effective against downy mildew and some pests. Insect [...]
UV Curing
UV curing objects can be divided into three types: Coatings, inks and adhesives. The coatings are mainly used as protective layers, such as wood coatings for home building materials, plastic and metal coatings used in home appliances and automobiles, and optical fiber and cable coating materials. The ink is mainly used in the printing field. Viscose is the most widely used in the field, such as the adhesion of glass and handicrafts, jewelry positioning, nail polish curing in the beauty industry, and medical device bonding. No matter UV coating, ink or glue, it has a natural advantage, that is, there [...]

Bloodstain Pattern Analysis and UV Flashlights
Bloodstain pattern analysis (BPA) is a forensic technique that examines the location, shape, size, and distribution of bloodstains to understand the events that occurred at a crime scene. Ultraviolet (UV) light plays a crucial role in enhancing the visibility of bloodstains, especially in challenging environments or on dark-colored surfaces. How UV Light Enhances Bloodstain Detection Fluorescence:?Many blood enhancement chemicals, such as luminol and fluorescein, emit a characteristic glow when exposed to UV light. This fluorescence makes bloodstains more visible, even in low-light conditions or on surfaces with complex patterns. Contrast:?UV light can improve the contrast between bloodstains and the background, [...]
UV Flashlights in Dermatology
Ultraviolet (UV) light, while often associated with sunburns, also has important applications in dermatology. Dermatologists use UV light, including that from UV flashlights, for both diagnostic and therapeutic purposes. Diagnostic Uses Pigmented Lesions:?UV light can help differentiate between benign and malignant pigmented lesions. For instance, some types of skin cancer, like basal cell carcinoma, may fluoresce differently under UV light compared to benign moles. Fungal Infections:?UV light can be used to detect fungal infections, especially those affecting the skin. Certain fungi fluoresce when exposed to UV light. Eczema and Psoriasis:?While not specific, UV light can sometimes highlight areas of inflammation [...]
Mineral Fluorescence and UV Flashlights
Ultraviolet (UV) flashlights have become indispensable tools for geologists and mineral collectors due to the phenomenon of mineral fluorescence. Many minerals exhibit a vibrant glow when exposed to UV light, revealing hidden colors and patterns that are not visible under normal lighting conditions. Understanding Mineral Fluorescence Mineral fluorescence occurs when a mineral absorbs ultraviolet radiation and then re-emits it as visible light. The color and intensity of the fluorescence vary depending on the mineral’s composition and the wavelength of the UV light. Factors such as impurities and crystal structure can also influence the fluorescence. Applications of UV Flashlights in Mineralogy [...]

Using UV Flashlights to Authenticate Banknotes
Ultraviolet (UV) light has become a standard tool in the field of numismatics for authenticating banknotes. Many modern banknotes incorporate security features that fluoresce under UV light, making it a valuable tool for detecting counterfeit currency. Security Threads:?Most modern banknotes contain security threads embedded in the paper. These threads are often made of materials that fluoresce under UV light in a specific pattern or color. Watermarks:?Watermarks are often designed to fluoresce under UV light, revealing hidden images or patterns that are difficult to counterfeit.
