Part Number BE026
Definition
The Model LTD is a simple instrument for measuring the transmission optical density of a film medium. It uses a high quality, ANSI specified, high color temperature incandescent source and a properly filtered optodetector element. Throat length is 7.5 in (19 cm), so it is able to reach points in the center of most media. The base acts as a light table for ease of operation. It is used primarily in traditional photographic processing, including radiography and micrographics. It has also been applied in various textile and materials plants.

Optical Density is defined as
log (Dzero / Dmeas), where Dzero is a fiduciary level corresponding
to zero attenuation, and Dmeas is the same light intensity, but attenuated
through the medium. The resulting dimensionless unit is referred
to as 'D'.
