NorthLab ProView™ LD
Fiber End Face Interferometer & Microscope
The NorthLab ProView LD interferometer is a highly advanced interferometer for precise measurement and inspection of optical fiber end faces with cladding diameters between 125 – 720μm. The interferometer is specifically designed for production lines where a simple, fast and very accurate fiber optic end face inspection is required. But the ProView LD is also well suited for R&D environments and for optical fiber cleaver maintenance purposes.
In many cases an interferometric fringe pattern can be very complicated to analyze and understand. For ease of use and optimal inspection speed the ProView LD includes highly advanced and fully automatic functions for 2D and 3D topographic analyses of the optical fiber end face surface. The software automatically indicates the angle, flatness and slope direction of the optical fiber end face.
To simplify the inspection process even further the ProView LD can be set to a “PASS/FAIL” mode. This function allows the operator to simply determine the optical fiber end face quality via color codes on the image.
In addition to cleave angle inspection the ProView LD measures several other properties such as optical fiber diameters and distances between defined points etc.
The ProView LD has a unique optical fiber clamping mechanism which accommodates standard fiber holders from FITEL or Fujikura but also allows the use of bare fibers. The standard ProView LD configuration for fiber holders includes a universal sized v-groove clamp assembly. Alternate configurations include adapters for SMA, FC/PC, ST/PC or LD80.
The NorthLab ProView LD interferometer has a compact design which makes it ideal for a production bench and to be used side-by-side with fiber optic fusion splicers, cleavers and other preparation tools. The ProView LD is connected and powered via a USB 3.0 cable and hosted by an external PC (not included).
