Send Drawing / RFQ Video Factory TourWe make one thing: precision rod lenses for rigid endoscope relay systems. Our lenses are currently in mass production for EU medical OEM customers — held to ≤3′ centration, every batch, with full COA.
We work engineer-to-engineer — you send the drawing, we review it for manufacturability and optical path compatibility before production starts. Our team works to ISO 10110, German DIN, and US MIL specs as required.
Serving: Tier 1 Assemblers • OEM Manufacturers
Our rod lenses are currently used by medical and industrial OEMs in Europe, Middle East, and Asia.
We are NOT a general repair parts supplier.
