CO2 Focusing lens

Matters needing attention
First, the convex side of the focusing lens is installed upward. After replacing the lens, it is necessary to fine-tune the lens barrel up and down, and fix it in the best effect position. The following points should be paid attention to to prevent the lens from bursting and extend the life of the lens.
1. The machine's air cooling failure causes the lens to overheat and burst, or the air cooling is not smooth, and the condensed water in the mirror tube causes the lens to burst.
2. The backspray or liquid that occupies the material of the carved object on the lens, which is easy to burst after a long time of uneven heat, should be cleaned with cotton swab dipped in anhydrous alcohol in time.
3 When dimming, the light path hits the junction of the side green of the lens and the mirror tube, which is easy to cause a burst.
