Type: User guide

DOMAILLE ENGINEERING DE8850 is a high-quality video microscope designed for inspecting fiber optic connectors in a research or production environment. It features a unique stage with inverted optics, allowing the operator to inspect connectors without removing them from the polishing fixture, increasing throughput during inspection. The DE8850 has four-position nosepiece for UPC and APC inspection, long working distance optics, and extensive range of inserts for various connector types.
