eyeglasses lens measure power clock Radiant table eyeglasses accessories for glasses shop

Professional to measure dioptric power of a lens and calculate the radius of curvature. For use with both glass and plastic lenses. Quickly identify and check base curve. The precision scale is uncrowded and easy to read. Convenient to use and easy to carry in a pocket.

• 1. Dual-Refractive Index Precision Designed for 1.49 and 1.60 refractive indices, this mechanical lens curvature gauge ensures accurate base curve measurements for standard and mid-index optical materials. Ideal for opticians and labs, it adapts to varying lens thickness and light-bending properties, delivering precise calculations critical for prescription accuracy.
• 2. Dual-Surface Measurement Technology Equipped with concave and convex surface detection, the tool provides dual-scale readouts for both lens types. This capability guarantees reliable assessment of lens curvature, ensuring optimal fit and performance in corrective eyewear and manufacturing processes.
• 3. Calibration-Ready & Durable Construction Featuring a built-in calibration mechanism, the gauge maintains long-term accuracy, while its stainless steel design resists wear in professional settings. The ergonomic grip and compact size enhance portability, making it suitable for workshops, clinics, or on-the-go use.
• 4. Traceable to Industry Standards Compliant with international measurement protocols, this tool offers consistent results aligned with global quality benchmarks. Its ability to measure refractive indices commonly used in low-to-mid power lenses (1.49-1.60) supports compliance in healthcare and manufacturing sectors.
• 5. Enhanced Optical Analysis By calculating lens power through curvature measurements, the gauge aids in verifying lens quality, detecting material inconsistencies, and ensuring proper alignment with patient prescriptions. A vital tool for reducing errors and optimizing optical performance in corrective lenses.
