Bureau Scales and ABFO#2

Bureau Scales

The original Bureau Scale is a specific corner square based on FBI guidelines and recommendations.  These items have been used for decades as official equipment for their photographers at crime scenes.  Though we have many similar items, this is the tool you get if you order it by name. Use the Bureau Scales as measurement guides when taking photographs out in the field, the black-and-white graphics are calculated to give the user clarity and great readability from a distance.

The Bureau Scale is 15cm x 30cm and many of the features of this corner square are similar to those in our Footprint and Tire Track Frame of References section, including the .06 TK plastic it is made from.  Each of these Bureau Scales are double sided with inverse colors on the opposite sides.  Black Background/White Graphics & White Background/Black Graphics is the standard color option.  This is a fixed angle corner square, no assembly or moving parts can be found. Each of the Bureau Scales ordered comes with a graphics-matching ruler and is 15cm long.

Another feature of our Bureau Scales are the Parralox Circles at each of the ends.  The Parralox Circles are a useful tool to the people who analyze the photographs that have our scales within the frame.  An investigator can examine the shape and displacement of the circle graphics in order to determine if the picture was taken at an angle or if there is a change of depth.  This is something that would be incredibly difficult to ascertain using rulers without these circles.  The Parralox Circles help to prove our commitment to making measuring devices that achieve the highest level of accuracy and functionality.

8 x 8cm Corner Square (like ABFO#2)

This 8 x 8cm Corner Square (in the style of an ABFO#2) is the first forensic corner square we made using suggestions from detectives in law enforcement. Though we have designed tons of new corner squares over the years, this golden-oldie is still a favorite to forensic investigators.

The graphics on this corner square read 5cm x 5cm and graduation tics extend out to 8cm on each leg. The gray shade featured on this product is 18% Photo Gray, which is a color balancing tone used in photography. Each of these corner squares is made standard of .03" thick plastic, but customizations are both welcome and encouraged.

A special feature this corner square shares with many of our products, is our unique Optirectilinear® graphics, which are the black and white rectangles seen on the product image on this page. These graphics extend the visible range of increments and help clarify readings taken from photographs.
