Deploy on factory conveyor vision stations where the camera sees mechanical vibration from motors, frames, or product impact. The 10G shock and vibration resistance helps preserve focus and image stability.
Prevents image aberration and focus drift in vibrating inspection cells.
Use with 2/3-inch 16 MP cameras and small-pixel sensors to inspect fine solder joints, component placement, or micro-features at close range down to 0.10 m.
Maintains usable sharpness for micron-level inspection tasks on compact targets.
Fit into rugged industrial quality cells where dust, impact, or mechanical stress are present and where a C-mount lens with compact 31.8 mm diameter is needed.
Provides a compact rugged lens option for inspection systems that need durable optics in constrained spaces.
