The X-28 lens scattering light tester is a scattering light testing optical platform developed specifically for EN167 related content, which can measure the corresponding luminous flux and center luminous flux of scattered light between 1.5 and 2. The horizontal swing mechanism and rotating fixture can effectively eliminate the prism effect at the measurement point, allowing the X-28 to measure glasses with refractive power.
