A blood detection flashlight is a specialized tool used by law enforcement, forensic investigators, and medical professionals to detect and enhance bloodstains at crime scenes or medical emergencies. It emits a specific wavelength of light that causes bloodstains to fluoresce, making them visible even if they are faint or have been cleaned.
Blood detection flashlights are an essential tool in forensic investigations as they allow investigators to locate and document bloodstains that may not be visible to the naked eye. This can help to establish the presence of a victim or suspect at a crime scene and provide valuable evidence for the investigation. Blood detection flashlights are also used in medical settings to help locate and treat wounds, and to ensure that surgical sites are free of blood.
