Setting-up dimensions which are not given in the above table can be calculated using the formulas below.
■ Formula for projection distance
Dimensions such as projection distances can be calculated from the diagonal length of the projected image
SD (m). Units for calculations: m
Values obtained with the formulas below contain a slight error.
