DescriptionSpecifications Models
The V100-CP holds the mirror at the post's axis of rotation (Post, post holder and mirror sold separately).

Most mirror mounts locate the reflective surface of the mirror ¼ to ½ in. in front of the mounting post’s rotation axis. This small distance creates a large inconvenience for anyone setting up an optical experiment using the mounting hole grid on an optical table. When the mirror mount is rotated to fold a beam, the mirror is no longer in line with table’s mounting hole grid and, likewise, the optical path (see image below). To correct this problem, mounting adaptors are needed to reposition the mirror into the optical path. This, however, takes more time, requires additional components, reduces stability, and takes additional table space. Even after all this has been done, if the optical path needs further adjustment, the mirror mount will need to be rotated and the adaptor plate repositioned again.

Newport’s new V100-CP CenterPoint™ mirror mount corrects this problem. How? The V100-CP positions the mirror’s surface right on the mounting post’s rotation axis and it does so while maintaining the standard 1-inch optical axis height. Optical setups can be created very quickly by using standard mounting posts mounted in the hole grid on an optical table; no adaptor plates or pedestal posts needed. If the optical path needs to change, no problem, simply rotate the post. In this way, the CenterPoint mirror mount can steer a beam well over 270 degrees. The CenterPoint design also lends itself to making periscopes, delay lines and polarizer inverters from fewer standard parts. One of the most useful aspects of the design is the ability to locate two or more V100-CPs on adjacent table mounting holes which are only 1-in apart. This is particularly valuable in high-density layouts. See the Product Detail tab for additional information on the aforementioned assemblies.


The V100-CP can be mounted to the center hole of a rotation stage like the RSP-1T using the RSA-1TI and a standard 8-32 (M4) nut.
