Black Emerald Fluorescent Powder 30g
Gem Powders are our newest magnetic fluorescent powders. Black Emerald appears to be a simple black magnetic powder. Apply to evidence and lift like regular black magnetic powders. However, these Gem powders also fluoresce just as the green fluorescent powders do. You can use these Gem powders as regular black magnetic powders, but you also have the option of fluorescing them.
To lift latent prints, use Black Emerald Magnetic Powder in the same way as any standard latent print powder. Alternatively, you can employ it as a fluorescent latent print powder in conjunction with a Forensic Light Source, laser, or ultraviolet light.
The Powder appears black when dusted on a surface, however, when illuminated, it fluoresces with the same intensity as green fluorescent powder and is especially sensitive to long wavelength ultraviolet light, about 365mm with no viewing filter necessary.
Here are a few reasons why fluorescent fingerprint powder is well-suited for specific materials:
- Fluorescent fingerprint powder offers versatility, as it can effectively lift prints from a wide range of surfaces, including non-porous materials like glass, metal, and plastic, as well as semi-porous surfaces such as paper and cardboard.. Its ability to adhere to various materials makes it a valuable tool for forensic investigators.
- Visibility under different lighting conditions: One of the key advantages of fluorescent fingerprint powder is its ability to fluoresce under specific wavelengths of light, such as ultraviolet (UV) or blue light. This property makes it especially useful for materials where traditional fingerprint powders may not provide sufficient contrast or visibility. Using an appropriate light source and fluorescent powder, it is easy to detect and photograph latent fingerprints, even on challenging surfaces.
- Contrast enhancement: Fluorescent fingerprint powder can enhance the contrast between the fingerprint and the underlying surface, making it easier for forensic experts to capture detailed images and analyze the ridge patterns. This is particularly beneficial when working with materials that have complex textures or patterns, as the fluorescent powder can make the fingerprint stand out more clearly.
- Minimization of background interference: In some cases, traditional fingerprint powders may leave a residue on the background surface, making it difficult to differentiate between the fingerprint and the surrounding area. Fluorescent powders, however, can minimize this issue by selectively adhering to the oils and residues left behind by the friction ridge skin, reducing the potential for background interference and improving the overall clarity of the fingerprint.
