Self-Centering Mounts
The self-centring mount helps us in fixing the lens at the same centre again & again. The repeatability & spring loaded jaws helps us in mounting different diameter with high accuracy. The spring-loaded jaws help us to hold the optics firmly avoiding overstressing of optics results in distorting surface & not too loose for a chance to slipping of optics. These mounts can be mounted in two ways in a setup, with standard posts or directly from bolts through holes which are given on the face of the mount.
