Aperture Size and Optical Path

Additional PlateScope Technical data:

PlateScope utilizes a large target aperture size. This gives the advantage of greater repeatability, with line screens of 150 lpi and lower. The optical path length is 190 millimeters using 2 internal precision mirrors. This permits greater Height insensitivity than with most instruments with path lengths less than 25 millimeters. Min and Max of the following:

• LPI or line screening of PlateScope?: specified as minimum of 75 lpi and maximum of 380 lpi
• Size of the true measuring spot?: approx. 1.5mm X 1.9mm
• Size of the patch you can measure?: Minimum should be a larger than the measuring spot mentioned above. The maximum is whatever you can imagine.
