What is the function of the Polilight in latent print examination?

The Polilight serves as an alternate light source in latent print examination, providing a specific range of wavelengths that enhance the visibility of latent prints present on various surfaces. This capability is essential because many latent prints are often not visible to the naked eye and can be obscured by contaminants or the background surface. By utilizing different wavelengths of light, the Polilight can help reveal these prints more effectively, allowing examiners to capture them for further analysis.

The specific design of the Polilight enables it to be used in conjunction with various detection techniques, making it invaluable in forensic investigations where latent fingerprints play a critical role in identifying individuals. Its versatility and effectiveness make it a crucial tool in the process of latent print analysis.

The other options, while related to forensics, do not pertain to the specific role of the Polilight. It is not a polishing tool, a chemistry analyzer, or a photographic printer, as those tools serve different purposes in the field of forensic science.
