Maximum flexibility for optical surface processing is now available with NOVA™. KrellTech has
integrated the proven performance and features of its industry leading Scepter, Trig and FLex
polishers into this configurable and cost-effective system.
NOVA™ supports a variety of polishing applications from connectors to waveguides, and bare fibers
to custom components. NOVA™ is scalable for R&D projects, high volume production, and the rigors
of harsh environments and field installation.
