4.3 Mounting range of companion flange (in factory range)
Mount the companion flange so that it satisfies the conditions of the following figure (Fig. 4
2). If the con-
ditions below are not satisfied, light cannot be received even if the light axis adjustment is performed by the
angle adjustment unit. In such a case, mount the companion flange again.
When
θ
(angle determined by laser light source and flange diameter) is bigger than 5°, mount the companion
flange within the
γ
angle (
≈
5°) inside the circle with A radius.
When the distance between laser light source and stack is long, or
θ
angle is less than 5° because flange di-
ameter is small, both A radius and
γ
angle will become smaller, and the mounting conditions will be strict.
