Uncoated Rod Lens Blanks Supplier | Coating Lab Partner

About HSD Optical

We make one thing: precision rod lens blanks for optical coating laboratories. Our blanks are precisely ground to your spec — you apply your proprietary AR, HR, or specialty coatings before shipping to your endoscope OEM customers.

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: Coating Laboratories • OEM Assemblers

Our rod lens blanks are currently supplied to coating labs and OEMs in Europe, Middle East, and Asia.

We are NOT a general repair parts supplier.
