Topcon CL-300P Computerized Lensmeter with Printer
The CL-300's new UV Measurement Function provides information on the ultraviolet transmittance in the range of 0% to 100%, providing reliable measurement results to both eyeglass and sunglass wearers.* UV Transmittance Measurement is performed with the light beam of 365 nm wavelength.
The CL-300 incorporates the green light reading beam, which is also known as e-line. Due to the wavelength of 546 nm, the e-line can be well-sensed by the human's eye and it is determined as a standard by ISO 7944. Using green light beam in our instrument enhances lens measurement precision and reduces the chance of error in the measurements.
Due to its new design, the lens support of the CL-300 is 6 mm more in height compared to the conventional model. This change enables smooth and trouble-free measurement of high-curve lenses, preventing from troublesome contact of the lens edge with external parts of the lens support.
