The 6250 mirrored target is used to check the
perpendicularity of a part by autoreflection or
autocollimation using the first-surface mirror, as well as to
position a part on the line of sight using the target
image. The target is unmounted and can be fitted
directly into the part to be positioned, or into any standard
sphere such as our 521-B.
