V-Groove Arrays

Flyer Download

High accuracy and consistency – Accumulative pitch within ±1µm for 96CH

Variable V-grooves with new levels of flexibility – allowing different pitches and angles to be implemented within the same array

Integrated mechanical positioning support

Compatible pitch alignment with corresponding microlens arrays

Fully customizable V-Groove patterns, including concave and convex designs

Versatile usage in optical modules, fiber connectors, PLC splitters in FTTX networks, AWGs in WDM systems and further scenarios

Ideal for flexible, multiple channel designs and large-scale production
