At Avantier, we specialize in the design, development, and manufacturing of small diameter lenses tailored for demanding applications—particularly in medical imaging, surgical instruments, and precision optical systems. With unmatched expertise in miniature optics, we deliver high-performance lenses that meet the strictest requirements in resolution, durability, and integration.
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)
