Object Name Camera
Description Inspectrograph 11 volt Infrared Eastman Kodak Graflex Fingerprint Camera. This is a camera used by Detectives to photograph trace evidence such as blood, semen, hair, dust and gun powder. The camera was powered by a 11 volt power source, used a film pack of 2 1/4 x 3 1/4 inch plate size. The lens is a Kodak Anastigmat 72mm f/6.3 and could make 1:1 photographic copies of fingerprint cards. A lens is recessed inside the flat brown rigid shroud and is pre-focused on the plane of the opening in the front of the shroud. To make an exposure, Detectives placed the shroud opening directly on the surface to be photographed. The power source illuminated the subject photographed. The shutter is a sliding lens cover that is moved out of the way when the shutter release lever is pressed, then is closed by a spring when the lever reaches the end of the travel. Actual exposure time is determined by how fast the Detective moves the lever, more exposure means longer pull. When the shutter release lever is pressed, the circuit closes, turning on the light source in the shroud. This camera is based on the science of spectrometry. This camera is the first use of spectrometry in criminal justice, that through the years has evolved into Mass Spectrometers. Jefferson County Sheriff Albert E. Jones is credited with purchasing the camera in 1917. He was the mayor of Golden, Colorado in 1916, a major league baseball player in 1900 and the future baseball coach at the Colorado School of Mines.
