Precision Optical Lens Inspection and Measurement System

Product Specifications

Technical details and manufacturing context for Precision Optical Lens Inspection and Measurement System

Definition

This standalone industrial inspection machine is designed for the precise measurement and quality control of optical lens elements during manufacturing. It performs non-contact optical testing to verify critical parameters such as surface form, centration, and focal length against design specifications. The system enables rapid pass/fail determination and data collection for statistical process control in high-volume lens production environments. It is essential for ensuring optical performance and reducing scrap rates in precision optics manufacturing.

The system integrates an interferometric or wavefront sensing source with precision mechanical positioning to capture optical performance data from lens samples. Automated analysis software compares measured wavefront errors to theoretical models, providing quantitative results for each parameter. The machine is built on a granite base with a stainless steel frame, ensuring stability and vibration damping. Precision glass optics and anodized aluminum components are used in the optical and mechanical subsystems.

Key specifications include a measurement wavelength range of 405–650 nm, a lens diameter measurement range of 0.5–200 mm, and a measurement speed of 0.5–5 seconds per measurement. Positioning accuracy is ±0.5 μm, and measurement accuracy for surface form error is ±0.1 μm with a vertical resolution of 0.01 μm. The system operates within a temperature range of 15–30 °C and a humidity range of 20–80% RH (non-condensing). It has an ingress protection rating of IP54 per IEC 60529, and the machine footprint is 1200×800×1600 mm with a weight of 350 kg. Power requirements are 220–240 VAC.

For any specific application, verify model-specific values and standards with the legal manufacturer or supplier. The listed parameters are reference ranges for directory purposes and must be confirmed for the actual model and application.

Working Principle

The system employs interferometric or wavefront sensing techniques to measure the optical wavefront of a lens under test. A light source with a wavelength between 405 and 650 nm illuminates the lens, and the reflected or transmitted wavefront is captured by a sensor. Precision mechanical stages position the lens with an accuracy of ±0.5 μm. The measured wavefront is compared to a theoretical model using automated analysis software, which calculates errors in surface form, centration, and focal length. The system provides pass/fail results and collects data for statistical process control.
