Wood lamp (Wood lamp), also known as Wood's lamp or filtered ultraviolet lamp, uses black glass to filter out visible light and only retains ultraviolet rays to pass through, thereby obtaining 320-400nm long-wave (peak 365nm) ultraviolet rays. Certain microorganisms and chemicals in nature will show specific colors under ultraviolet irradiation in this band. Using this feature, Wood's lamp can be of great use in our daily lives.

Hygiene inspection: Wood lamp can be said to be good news for germophobe! If the toilet, washbasin, carpet, sofa, and bed at home or in a hotel are not cleaned, there will be a large number of microorganisms and foreign matter on them, such as mold, mites, and stains. After being illuminated by a Wood lamp, these microorganisms and foreign matter will emit Bright blue light makes it easy to judge the cleanliness of the living environment. If you have a cat/dog that pees everywhere, whether it is wet or dried, it will show up under the illumination of a Wood lamp.

Skin abnormality detection: Wood's lamp is known as the "microscope" of the skin and is widely used to identify melanin deficiency, pigmentation and various types of germs. The fluorescent color displayed by the Wood's lamp irradiating the skin lesions can be found in the "Wood's lamp examination color comparison table". to diagnose the type of skin abnormality.

Fungal examination of cats and dogs: The only thing that worries the “cat/dog” is that cats/dogs are infected with fungus. Fungus can cause pets to scratch frequently, lose their hair, and become languid. This is when the Wood's lamp comes in handy. When you see a cat/dog scratching the same spot frequently, use a Wood's lamp to illuminate it in a dark environment. If the hair shows green fluorescence, it means that the pet is infected with fungus. Timely measures should be taken to intervene.

In addition to the applications introduced above, Wood's lamp is also used in automobile engine oil leakage detection, glass and metal adhesive curing, etc., so it is very necessary to always have a Wood's lamp at home. Because Wood lamps are so widely used, some unscrupulous merchants have come up with the idea of shoddy products: using ultraviolet flashlights to pass off as Wood lamps. The irradiation area of these defective products is small, and some even have seriously substandard irradiation intensity, causing users to misjudge or miss details. As an indispensable tool in the family toolbox, everyone still needs to distinguish between genuine and fake products and choose carefully to avoid being deceived!
