Why Small Diameter Lenses Matter
In compact optical systems, miniaturized lenses play a critical role in ensuring image clarity, structural integrity, and environmental reliability. These lenses are essential in applications such as:
- Endoscopes (2.7–10 mm lens diameters)
- Surgical microscopes
- Ophthalmic instruments
- Portable medical imaging devices
- Optical coherence tomography (OCT) systems
Our small diameter lenses are custom-built to perform under extreme conditions—high temperatures, pressure, chemical sterilization—while maintaining superior imaging accuracy.
Key Features of Our Small Diameter Lenses
✔ High Imaging Performance in a Compact Design
- Optimized for aberration correction, stray light suppression, and field of view–resolution balance
- Aspheric surfaces used to minimize spherical and chromatic aberrations without increasing lens size
- Multi-layer anti-reflection coatings and internal barrel blackening for ghost-free imaging
✔ Precision Manufacturing for Medical Environments
- Medical-grade designs resistant to high-pressure steam sterilization (up to 135°C, 2 atm)
- Sapphire lens options for scratch resistance and chemical durability
- IPX8-rated designs with sealed barrels and UV-cured adhesives for liquid and disinfectant resistance
✔ Ultra-Precision Machining and Assembly
- CNC and magnetorheological polishing for aspheric lens accuracy (λ/10 or better)
- Laser cutting and ion beam etching for micron-level precision
- Vacuum-assisted alignment and cleanroom assembly (ISO Class 6 or better)
