Biological material detector

Technical Parameters 1,60W LED violet light source provides high brightness illumination for biological evidence discovery. When a 415nm band pass Interference filter is installed on a white light source, the light source will output 415nm Violet Light. When the blood stain was irradiated with violet light, the blood stain absorbed 415nm Violet light strongly. The result was that the color of the blood stain deepened and the contrast between the blood stain and the background increased. UV special filter is a long wave Interference filter, this filter can completely block 415nm violet light, while maximizing the guarantee of fluorescence through. Biological evidence such as semen stains, saliva stains, sweat stains, urine stains, hair, Dandruff, bones, teeth, fragments and Dandruff were irradiated by 415nm Violet Light. 2.60W LED UV light source 60W LED bulb emits UV light with a central wavelength of 380nm and filters the visible light through the UV filter. It can be used to irradiate biological evidence, such as semen stains, saliva stains, sweat stains, urine stains, hair, dandruff, bone, tooth fragments, and Dandruff. 3.60W LED blue light source 60W LED bulbs emit blue light with a central wavelength of 450nm. A band pass Interference filter with a central wavelength of 450nm is installed in front of the light source to make the output spectrum curve steeper. Blue light special filter is a long wave pass Interference filter, this filter can completely block 450 nm blue light, at the same time, can maximize the guarantee of fluorescence through. Biological evidence such as semen stains, saliva stains, sweat stains, urine stains, hair, dandruff, bone, tooth fragments and skin debris were irradiated by 450nm blue light.
