The anti-fogging tester is used to test the anti-fogging function of spectacles. It is suitable for testing whether the lenses with anti-fogging and waterproof function can maintain a certain anti-fogging effect under the adhesion of water vapour, and can also be used to test the friction resistance of lenses.
Application:
To measure the anti-fogging effect of the lens, a laser light source is emitted by the laser, which penetrates the lens through refraction and reflection.
The result is determined:
After the laser light has passed through the lens, the sample is tested according to the method specified in section 6.10 of the GB/T 32166.2-2015 standard, the sample should not be fogged for at least 8S, compared with the power value when there is no fog, maintaining at least 80% is considered good, then it has an anti-fogging effect, otherwise it is no anti-fogging effect.
