T-TESTER is an instrument for measuring the transmittance of sunglasses with gradient and solid colour lenses.
Instrument to measure the TV % and uniformity in TV% of gradient and solid colour lenses mounted in sport and fashion sunglasses.
Reference standards: ISO 12312.1 – ANSI Z80.3 – AS/NZ 1067
T-TESTER allows to measure in few seconds the transmittance of each single lens of the mounted sunglass and performs the calculation of the uniformity of transmittance as foreseen by the international reference standards. Very useful with gradient lenses T-TESTER classify each single lens according to the standards requirement and return the information PASS/FAIL of uniformity between the two lenses particularly conditioned by the height of the gradient lenses.
Measurements are performed as requested by the standards in “as worn” conditions; this reflect the real use of the sunglass.
T-TESTER, with its own dedicated software, can work with any desk top or lab top or with the same computer used by OPTITESTER.
