The SR-02 device for measuring the reflectivity of anti reflective film on eyeglass lenses was developed in accordance with the requirements of GB10810.4-2012 and ISO8980.4-2006 standards. Firstly, it meets the various requirements for the single-sided light reflectivity of anti reflective film in ISO8980.4 (which is also equivalent to the requirements for single-sided light reflectivity in GB10810.4-2012). At the same time, according to the testing principle of the American standard ASTM F1252, it has been developed to meet the requirements for the double-sided reflectivity of lenses in GB10810.4.

The SR-02 eyeglass lens anti reflective film reflectance measurement device can automatically detect important optical performance indicators such as single and double-sided light reflectance, average reflectance, and film uniformity of coated eyeglass lenses.
