The Contact Lens Luminous Transmittance Analyzer is a precision instrument designed to measure the spectral transmittance of soft and hard contact lenses, including hydrogel, silicone hydrogel, artificial cornea, RGP, and Ortho-K lenses. The instrument integrates a built-in integrating sphere to ensure highly accurate measurements that comply with international standards. It features a specially designed lens clamp that prevents deformation, enabling reliable and repeatable results. This analyzer is ideal for manufacturers, laboratories, and research institutions focusing on optical performance evaluation and quality control of contact lenses.
Application
(1) Measurement of spectral transmittance for soft contact lenses (hydrogel/silicone hydrogel/artificial cornea).
(2) Measurement of spectral transmittance for hard contact lenses (RGP, Ortho-K).
(3) Quality control in contact lens manufacturing.
(4) Research and development of new lens materials with specific optical properties.
(5) Verification of compliance with national and international standards for ophthalmic optics.
(6) Optical characterization for product certification and regulatory submission.
Standards
(1) GB/T 11417.5 – Ophthalmic optics – Contact lenses – Spectral transmittance test method.
(2) ISO 18369 – Ophthalmic optics – Contact lenses – Requirements and test methods.
(3) ANSI Z80.20 – American National Standard for Contact Lens Optical Properties.
(4) ISO 8980-4 – Ophthalmic optics – Lenses for correction of vision – Part 4: Transmittance specifications.
(5) IEC 61010 – Safety requirements for laboratory and measuring equipment.
Features
(1) Built-in integrating sphere ensures uniform illumination and accurate lens transmittance measurement.
(2) Specially designed lens clamp prevents deformation for both soft and hard lenses.
(3) Wide spectral range (280–780 nm) for comprehensive optical evaluation.
(4) Adjustable wavelength interval (1–10 nm) for high-resolution measurement.
(5) High measurement accuracy with transmittance repeatability <1% and absolute error <1%.
(6) Supports measurement in air or solution (pure water or standard saline).
(7) User-friendly software interface compatible with Windows 7/8/10/11.
(8) Data output via USB for easy integration with laboratory information systems.
