Rod Lens & Micro Lens Supply for Two Supply-Chain Roles

We cold-work glass for two very different customers: coating laboratories that run their own coating lines, and endoscope OEM assemblers that need finished, ready-to-assemble optics. Same factory, same tolerances, different packaging.

For Optical Coating Laboratories

Uncoated Rod Lens Blanks (White Parts)

Precision-ground, polished, uncoated blanks that drop straight into your vacuum chamber or polishing fixtures — no rework. For Φ2.8 mm rod lenses we routinely hold outer diameter to 2.76–2.78 mm (fit tolerance −0.02 to −0.04 mm), centration ≤ 3′, surface 40/20, edge chipping ≤0.05 mm, batch COA with full glass traceability.

  • Line-qualification samples for coating laboratories
  • Glass materials: per customer drawing, traceable per batch
  • MOQ 10 pcs; sample lead time confirmed against your drawing's complexity

For Endoscope & Ureteroscope OEM Assemblers

Fully Coated, Ready-to-Assemble Lenses

Ground, polished, broadband AR coated (400–700 nm) rod and micro lenses inspected on a per-batch sampling plan, so they go straight into your assembly line. Rod lenses Φ1.2–8.0 mm, micro lenses Φ1.0 mm / Φ1.19 mm, centration ≤ 3′, surface 40/20 per MIL-PRF-13830B, edge chipping ≤0.05 mm, batch COA with measured values.

  • Engineer-to-engineer drawing review before production
  • ISO 10110 / DIN / MIL drawing standards accepted
  • NDA in place before technical discussions

Quick Answer: HSD Optical serves two buyers: coating laboratories that need uncoated rod and micro lens blanks, and endoscope OEMs that need finished, coated lenses. Both paths use the same make-to-print process, ISO 10110 tolerances and measured batch COA.
