grating force-controlled CNC polishing system
This equipment uses an industrial-grade six-axis robotic arm as the motion execution unit, equipped with a high-response force-control polishing module and a digital process control system, forming an intelligent optical element processing platform. The robotic arm positioning accuracy reaches ±0.02mm, with repeat positioning accuracy better than ±0.01mm, combined with a 0.1N-class closed-loop force control system to ensure dynamic stability during processing.

GPST-1000 Sliding Plasma Fiber Coating Stripper
Optical Production Equipment
Lightel
Applicable Coatings: Polyimide/Hard Polymer/Silicone/Acrylate/Metal/Double-layer Coating, etc. Cladding Diameter Range: 80〜1200 μm Window Strip Length: 5〜100 mm
Based on our sliding plasma stripping technology, Lightel developed the GPST-1000 stripper for quick and easy fiber coating stripping. The GPST-1000 allows operators to easily strip almost all types of fiber coatings, including the most stubborn fiber coatings such as carbon or polyimide. The device supports end stripping and automotive stripping, with detachable strip length. The strip edges are clean, and its non-contact process eliminates the risks associated with chemical stripping and blade-based mechanical systems.
