Comprehensive Measurements for Optimal Lens Quality
The MCT-3000 non contact measures a range of critical parameters that ensure high-quality optical performance. These include:
- Sag (Sagittal Height):
- The vertical distance from the center of the lens’s back surface to a flat reference plane is measured.. This plane intersects the lens’s outermost edges. This parameter reflects the complete curvature of the lens and directly impacts how well it fits on the eye.
- Center Thickness:
- Real-time thickness measurement is important. It measures the lens’s thickness at its center. This measurement is vital for comfort and optical performance.
- Air Gap:
- The MCT-3000 measures the air gap in the mold and the lens material. It also checks the gap between the lens and the cornea accurately. This comprehensive measurement is critical for maintaining proper oxygen flow and overall eye health.
- Diameter:
- Accurate measurement of the lens’s width to ensure proper positioning on the eye.
- Group Refractive Index:
- Essential for understanding the lens’s optical properties and ensuring the correct light-bending performance.
By taking these measurements at the start of production, the MCT-3000 shows early signs of quality problems. This helps manufacturers make quick changes and avoid expensive defects.
The Complexity of Measuring Sag with Conventional Technologies
Traditional measurement methods often rely on simple imaging techniques that capture only a two-dimensional view of the lens. These methods cannot accurately measure the full curvature of the lens, leading to incorrect Sag values. Inaccurate measurements can result in:
- Improper lens fitting, causing discomfort and reduced oxygen transmission.
- Inconsistent quality control, leading to higher scrap rates and increased production costs.
- Limited ability to detect subtle variations in lens geometry—especially in lenses with complex curvature profiles.
This problem lenses that need exact optical properties.
Even a small error in Sag measurement can change how they work.
Versatility Across Contact Lens Types
Ortho-K Lenses
Ortho-K lenses are designed to reshape the cornea overnight, providing clear vision during the day. Measuring Sag accurately is a lot important. Even small changes in lens curvature can cause poor reshaping of the cornea. Precise Sag measurement ensures that the lens performs its function effectively and safely.
Because Ortho-K lenses have complex shapes, regular methods often struggle to capture their full curve. The MCT-3000 uses advanced, non-contact laser technology. It measures every layer of the lens in detail.
Soft Contact Lenses:
For soft contact lenses, a good fit is important. Measuring the sag correctly is essential.
Knowing the center thickness and air gap helps. This prevents issues like the lens “floats” or being too tight. A proper fit leads to better comfort and performance.
A fit occurs when the center of the lens touches the cornea. The edges of the lens sit above the eye. A tight fit means the lens edges touch the cornea, while the center floats.
Integration into Automated Production Lines
A standout feature of the MCT-3000 is its seamless integration into automated production lines. This system operates continuously, providing real-time quality control directly on the assembly line. With its automated data collection and immediate feedback, manufacturers can:
- Detect Defects Early: Identify any deviations from quality standards at the outset, preventing the continuation of faulty production.
- Enhance Production Efficiency: Minimize downtime and manual interventions, ensuring smooth and consistent production.
- Lower Costs: Reduce waste by identifying errors early, leading to significant cost savings.
- Improve Yields: Maintain consistent product quality and optimize manufacturing processes, resulting in higher production yields.
Cost Savings and Improved Yields
By incorporating the MCT-3000 into your production process, you can:
- Reduce Waste: Early quality checks prevent the manufacture of defective lenses.
- Increase Yields: Consistent, automated measurements ensure that only products meeting strict quality standards proceed through production.
- Lower Costs: Real-time quality control reduces scrap rates and rework, ultimately saving time and resources.
