3-Part Folding Scale, Metric
1005951ABFO No. 2 Photomacrographic ScaleDescription
Designed by the American Board of Forensic Odontology (ABFO), this scale has become the standard for bitemark measurement and photography. The incorporation of three circles is useful in helping to compensate for distortion resulting from oblique camera angles. Graduations are all metric except for the width of the legs, which are 1" wide. The 1cm division lines are traced and extended across the photographic print to grid an image. Measurements within the image are then made relative to these inscribed 1cm grid lines to compensate for any distortion resulting from nonparallelism between the film and the object planes.
1005955Inch L-Shaped ScaleDescription
Similar in shape to the ABFO No. 2 scale, this scale is printed with inch markings instead of metric.
1007849Hinged L-Reference ScaleDescription
This unique, two-sided metric scale can be folded for easy storage or used as a straight scale. The short arm of the scale can be adjusted to any angle, providing versatility. The two-tone color scheme provides maximum contrast for any photographic situation. One face is white with black markings. The reverse is black with white markings. Alternating black and white bands provide contrast at a distance. Neutral gray bars assist in color correction and crosshairs at each end provide photogrammetry corrections.
1013536L-Shaped Scale, 180 x 450mm, ClearDescription
Made to rigid FBI specifications, this L-Shaped scale provides maximum contrast by featuring black markings on a clear background. Alternating black and clear bands provide an excellent visual reference from a distance and crosshairs at each end provide a means for checking and correcting perspective distortion
1005953Bureau Scales, Set of 2Description
Made to rigid FBI specifications, the “Bureau” scale set contains a 15cm x 30cm L-Shaped scale and a 15cm straight scale. The scale set provides maximum contrast by featuring black markings on a white background on one side and white markings on a black background on the reverse. Alternating black and white bands provide an excellent visual reference from a distance and crosshairs at each end provide a means for checking and correcting perspective distortion. The L-shaped scale is rigid and will always provide an exact 90° scale.
1005954Fluorescent Inch L-Shaped Scales, Pack of 5Description
Fluorescent INCH L-Shaped Scales, Pack of 5Designed for use with a Forensic Light Source or ultraviolet lamp, this fluorescent L-shaped scale is ideal for photographing evidence such as latent prints developed with fluorescent dyes or powders, or for photography of fluorescing body fluid stains at crime scenes or on evidence. Inch markings are printed with fluorescent ink on a heavy, matte cardstock. Alternating bars every inch help to identify measurements in grossly over- or underexposed photographs. The L-shape of the scale and the crosshairs at each end provide lines of reference for the measurements and ensure the scale is parallel with the film plane.
