Our promotional video reveals the five critical stages of the industrial turning process. Each stage has a clear goal, specific quality measures, and tools to measure them. In the end, you can trust the optical performance.
Stage 1: Blank Inspection
Ensure optical and material uniformity of the raw blank before machining begins.
Measured Parameters:
- Refractive Index at sub-micron resolution Instrument
MCT-3000 – measures contact lens thickness and position for any lens material up to 1.0 μm accuracy and can be integrated into automated lines or used standalone.
Why It Matters?
A consistent refractive index provides a stable foundation for turning, minimizes material waste, and maintains process consistency.
Stage 2: Chuck Alignment & Rough Turning
Align the workpiece and remove excess material under controlled conditions.
Measured Parameters:
- Radios of curvature (Front & Base Curves – ROC)
- Tool offset compensation
- Cylinder
- Axis
- Sagittal height (SAG)
- Surface quality
- Aspheric
Brass 2000 – A robust system for measurement, inspection, and analysis of surfaces in the contact lens industry. It inspects the entire optical quality in one shot without contacting the surface, assists in lathe setup, and detects cutting errors.
Brass 3k – The Brass 3K is designed for measuring surfaces in the contact lens industry, including reflected wavefront analysis and lathe set-up assistance.
MetroCell – The Metro-Cell is a modular metrology platform for lens production, providing a non-destructive, fully automated solution driven by precision, data management, and connectivity, with flexibility to integrate any production data.
MCT 3000- measures contact lens thickness and position for any lens material up to 1.0 μm accuracy and can be integrated into automated lines or used standalone.
Why It Matters?
Accurate preliminary material removal sets the stage for precise final turning, boosts production speed, and reduces costly rejects.
Stage 3: Final Turning
Generate the final geometric profile, including center thickness and sagittal height
Measured Parameters:
- Center Thickness
- Sagittal Height
- Aspheric
MCT-3000 – The MCT 3000 measures contact lens thickness and position for any lens material up to 1.0 μm accuracy and can be integrated into automated lines or used standalone.
Brass 2000 – A robust system for measurement, inspection, and analysis of surfaces in the contact lens industry.
It inspects the entire optical quality in one shot without contacting the surface, assists in lathe setup, and detects cutting errors.
Brass 3k – The Brass 3K is designed for measuring surfaces in the contact lens industry, including reflected wavefront analysis and lathe set-up assistance.
Why It Matters?
Combining complementary measurement systems provides dual verification, ensuring compliance with Lensmaker’s Equation requirements and consistent user comfort.
Stage 4: Final Optical QA
Verify all optical specifications before packaging.
- Sphere power
- Cylinder
- Axis
- Prism
- Wavefront
- Addition
- Diameter
- MTF
Contest 2 – A contact lens measurement and analysis system that provides rapid, precise, and consistent measurements for various designs, including complex lenses.
Contest MP –Maps and analyzes contact lenses in mass production mode, providing fast, precise measurements of diverse range of designs, including wet, dry, and pre-hydrated lenses.
Why It Matters?
Comprehensive optical verification ensures maximum visual clarity, precise correction, and reliable performance across varying ambient conditions.
Stage 5: Final Cosmetic QA
Detect and reject any lenses with outward cosmetic defects.
Inspected Defects:
- Edge chips
- Lathe marks
- Scratches
- polish marks
- orange-peel
V‑PRO GS3 – A machine vision system for inspecting contact lens cosmetics and dimensions, providing high-resolution imaging and manual or automatic optical inspection, aiding in QA digitization.
Why It Matters?
Flawless cosmetic appearance strengthens brand reputation and ensures end-user confidence in product quality.
