Brief introduction: TR1504 can be used to determine the dry and wet state of all types of contact lenses. Whether it is single-focus, torus, multi-focus or multi-focus lenses, the instrument has unparalleled repeatability and reproducibility. The instrument does not need to be calibrated every day, and its humanized operation interface can provide a variety of operations and support full traceability. Product features: 1. Suitable for rigid oxygen permeable contact lenses and soft contact lenses 2, can be measured spherical, multi-focus, aspheric surface, ring surface and other contact lenses 3. High-resolution optical focus distribution map and optical focus data < 4. Ring and curved contact lens markers automatically recognized 5. Determine the dynamic range from 30.00D to +30.00D 6. Zernike coefficient is used for wavefront analysis 7. Wet and dry measurement is ok Application scope: Apply to all types of contact lenses Hardware specifications: Principle of detection: phase-shifting Schlieren technique is applied Detection area: 15*15mm2 Through aperture: the maximum diameter is 15mm Light wavelength: 546nm Imaging quality: the image pixel is 1024*1024 Absolute optical focus measurement range: + / - 40D(5mm aperture), 30D(8mm aperture) Repeatability: better than 0.007D Repeatability variance: 0.05d External dimensions: 170*220*590mm3 Software support: Measurement environment: dry and wet detection environment (optical focus is achieved by numerical conversion of back radian, lens thickness and refractive index) Spherical lens detection: spherical lens optical focus, cylindrical lens optical focus, prismatic degree, product quality factors Circular surface detection: spherical lens optical focus, cylindrical lens optical focus, cylindrical mirror axis, prism, product quality factors Multi-focus detection: radial distribution of optical focus, near focus, far focus, central myopia or central hyperopia in the annular area Multi-focal surface detection: it has all the functions of multi-focal detection and can automatically detect the axis of column mirror Batch measurement data output: text file output, each detection result has an independent data line, data statistics and data report Single measurement data output: right click can store the output image and optical focus distribution map data in CSV text format or BMP image format
