HH1-062-13T GLASS LENS

1, Lens focal length 42.1mm;.

2, Lens type: with microstructure.

3, Lens molding is complete, no defects such as lack of material, flying edge, scratches, shrinkage pit, rust, cracking, yellowing, deformation, etc.; no more than the limit of samples of bubbles, gas lines, black spots; no more than the limit of samples of bubbles, gas lines, black spots.

line, black spot.

4、Surface roughness:Ra0.2

5, abrasion resistance: the experimental piece is placed on the abrasion machine, using the CS-10F specification grinding wheel, load 500g of

The test piece is put on the abrasion machine, using CS-10F specification abrasive wheel, loaded with 500g pressure, round trip for 1000 times, and then measure the haze of the contact part of the abrasive wheel.

Then measure the haze of the contact part of the grinding wheel, the haze before and after the experiment as the conclusion of the wear resistance experiment, to be

HZ<3.5.

6, to meet the BT/SGMWJ0849-2015 “automobile banned substance requirements”;.

7、See three-dimensional data for details of unlabeled dimensions.
