Request InfoMKS/NewportThe BPH Post Holder is a patent-pending reinvention of the classical optical post holder, combining a slim slotted base with a unique post holder. The top surface has a series of kinematic indentations that, when used with the BPH Post Collar, provide repeatable rotational alignment and indexing. The base features both angled and straight reference surfaces, allowing edge-to-edge placement of adjacent post holders. BPH Post Holders are available in four standard heights.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra February 2023 IssueHolographic Grating SpectrometerThe HG10 Holographic Grating Spectrometer from Thorlabs Inc. is a fiber-based, high-speed device that provides sub-nm resolution in the 810- to 965-nm optical range.
