The reticle, positioned directly against against the integrating sphere, is capable of measuring fonts up to 35mm in size with a very high degree of precision. The markings on the reticle are low reflection and high contrast, allowing for easy readability. The physical setup of the optics lab will allow for the display to be flush against the reticle, providing optimum focus and accuracy in the measurements.
The original system is composed (R-to-L in the picture to the left) of a Canon EOS D30 Digital SLR camera, a Leica Z6 APO long-distance microscope zoom lens, an iris diaphragm to control the field of view, and an in-line integrating sphere with a 3-watt lamp as a uniform light source - all horizontally mounted on a vibration-free optics table.
