Helia Photonics: the ultimate innovators in thin film optical coatings

Our Krelltech™ die-level polishing tool has been specifically optimized to achieve optical facets for PICs. Devices are held against material-specific grinding/polishing pucks with controllable force and speed, yielding highly reliable erosion rates for fine control of the polishing line, and a gentle process compatible with very fine structures such as patterned trenches.
