Optical Post Holder, Slotted-Base, 4.0 in. Height, 0.5 in. Posts

Non-Bridging Slotted-Base Optical Post Holders

The BPH-4 Slotted-Base Post Holder is a patent pending re-invention of the classical optical post holder, combining a slim slotted base with a unique post holder. The top surface of the post holder has a series of kinematic indentations which, when used with the BPH-C-5 Post Collar, provide repeatable rotational alignment and indexing at 45° increments. The base features both angled and straight reference surfaces allowing edge-to-edge placement of adjacent post holders and, with the addition of the BPH-XB-5 Base Extender, can convert to a double-slotted base. The flat bottom also makes mounting more versatile and improves stability.
