Our Company
Focused on What We Do Best
Founded in 2009, HSD Optical is a specialized Tier 2 manufacturer of precision optical components for medical endoscopy. Based in Nanjing, China, with a dedicated team of 30 specialists.
All optics are produced in-house by our own cold-working team — grinding, polishing, centering and (when needed) AR coating.
We supply uncoated blanks to coating laboratories and finished lenses to OEM assemblers — serving the full upstream supply chain of rigid endoscopes and ureteroscopes worldwide.
