Product Description

Summary: wood's lamp is also called all lights or filtering ultraviolet lamp. it uses the wave ultraviolet absorption melanin, through the principle of containing nickel hydrogen filter piece of a 320— 400 nm long wave ultraviolet ray, garnish with long wave ultraviolet ray trouble place. if black element is strong, reduce refractive index shows light color; and if black element is weak, refractive index increased show dark. as a dermatologist clinical application of a kind of auxiliary examination method, it is used widely. detailed information as below: detect abnormal disease, such as diagnosing pigment vitiligo and ascertaining its curative effect, determining the classification of chloasma; detect skin infections, guide to find out the early diagnosis of red tinea infection and hair fungal infections; diagnosis chaff spores feed hair follicle infection and so on; detect porphyrin metabolic abnormalities diseases; avoid the excessive medication; chemical grinding monitoring local using of the frequency of drug; pharmacy diagnosis by photodynamic therapy. the bellows are four toshiba wood tube, and the above is an eight times magnifying glass. 1, tinea capitis: the light of yellow tinea is dark under the wood lamp; and the white tinea shows bright green fluorescence. the wood is used to identify white tinea and yellow tinea. it is also a guide of clinical judgment. 2, tinea versicolor: the disease under wood fluorescent lamp shows tan, theoretically, chaff spore fungus follicle inflammation also shows tan. but acne propionic acid bacteria cause inflammation of the hair follicles shows palm red or orange. it helps to distinguish between the two kinds of hair follicles inflammation. 3, red tinea: subtle coryneform bacteria be caused by, is a species diphtheria bacili, often hair at thigh, scrotal contact groin, subaxillaries, hip joints, breast, often without self-conscious symptom, performance for edge irregular skin red or brown spot piece under the wood lamp is coral red. 4, yemao tinea: by fiber is caused by the coryneform bacteria, kind of diphtheria bacili one. mainly in yemao, it shows green fluorescence under the wood lamp. 5, acne: it shows palm red or orange fluorescence under the wood lamp. 6, some pigment les ions 1) chloasma: it is a common disease among middle-aged women. at present, it is very difficult to treat. its causes have primary and secondary. it is divided into four types: superficial type, leather type, mixed and indefinite type. 2) other pigment disease, such as senile plaque, coffee spot, nerve fibroma, freckles, etc. shading dry skin disease and senile plaque are more obvious under the wood lamp. 7, some skin cancer: squamous cell carcinoma is bright red fluorescent, and basal cell carcinoma will not show fluorescence; melanoma is black under the wood lamp, under a passive congestion for burgundy. second, technical data volume: 47 * 177 * 151 power supply voltage: 220 v power frequency: 50 hz supply current: 0.35a power factor: 0.31— 0.33 uv light tube: 4 * 4 w a magnifying glass: 50 * 100 mm peak: 365 nm
