PentaPod® Multi-Axis Positioner

The ProView Theta LD / XD from NorthLab is an advanced interferometric inspection and alignment system designed to fundamentally enhance polarization‑maintaining (PM) and specialty fiber splicing. Acting as a powerful extension to standard fusion splicers, the ProView Theta adds detailed end‑face topography analysis and geometry‑based alignment control—capabilities that are increasingly essential as fiber designs grow more complex and demanding.Modern photonics applications rely on fibers with non‑circular structures, intricate internal features, and large cladding diameters. In these cases, even minute cleave angle errors or rotational misalignment can seriously degrade splice quality, optical performance, or long‑term reliability. The ProView Theta addresses this challenge by functioning as a “third eye” for PM splicers. Connected to the fusion splicer via an external PC, it analyzes the fiber end faces in 2D and 3D, generates precise digital templates, and enables exact theta alignment prior to splicing.Specifically designed to minimize the cleave angle gap for large‑diameter fibers, the ProView Theta ensures that complex end‑face structures are correctly matched and aligned before fusion. By combining fast interferometric inspection with intelligent software‑guided alignment, the system transforms manual, experience‑based splicing into a controlled and repeatable process—helping users achieve flawless splices even with the most challenging fiber geometries.Key featuresFor fiber cladding diameters: LD model: 125 to 800 μm, XD model: 250 to 1200 μm2D and 3D topographyFringe & Inspection mode from PC Controller GUI§Very fast inspection time with automatic angle estimation§Optional use of PASS/FAIL cleave angle indicationInspection of end face properties such as flatness, perpendicularity, hackles and contaminationGrab and save 2D and 3D images and cleave dataUser software calibration utility for extreme accuracyApplicationsThe ProView Theta is ideally suited for polarization‑maintaining (PM) fiber splicing, where precise angular alignment is critical to preserving polarization extinction ratio (PER). Its ability to minimize cleave angle mismatch and optimize theta alignment results in lower splice loss and improved optical performance.It is equally valuable for Photonic Crystal Fibers (PCF), air‑clad fibers, and multi‑core fibers, where internal structures must be carefully matched to maintain optical functionality. Traditional splicers often lack the visibility required for these fibers, but the ProView Theta enables confident, geometry‑aware alignment.The system excels with non‑cylindrical and complex fiber geometries, including hexagonal, octagonal, and D‑shaped fibers commonly used in high‑power laser delivery, sensing, and specialty photonics. In large‑diameter fiber splicing, where small angular errors have amplified consequences, the ProView Theta delivers a decisive process advantage.Typical application environments include advanced photonics R&D, pilot manufacturing, and high‑end production lines, where flexibility, repeatability, and future readiness are essential.What’s next?The ProView Theta LD/XD positions NorthLab users for the next generation of fiber technology. As fiber architectures continue to evolve—becoming larger, more complex, and more application‑specific—the need for advanced inspection and alignment tools will only grow.By transforming end‑face inspection and angular alignment into a controlled, data‑driven process, the ProView Theta ensures that today’s fusion splicing equipment remains effective tomorrow. Whether supporting cutting‑edge research, transferring new fiber designs into production, or improving yield and consistency in existing processes, the ProView Theta delivers a flexible, future‑proof solution—bringing confidence, precision, and clarity to even the most challenging fiber splicing applications.
