How to use fiber optic cleaner and matters needing attention

The first step is to check the jumper lens of the fiber laser.
The methods generally include:
Strong light irradiation method
Generally, a strong light flashlight is used to illuminate the observation lens, and a tilted rotating lens or flashlight is used to observe whether the lens has stains and traces through the rotating light.
Interference fringe method
If the accessory has an interference light source, you can observe whether there is pollution on the lens by reflecting light and dark interference fringes.
The second step is to preliminarily judge the degree of contamination of the lens through the inspection results, and then take corresponding measures to deal with it.
There are generally three categories:
Mild dust
Optical lenses generally attract some dust on the surface due to static electricity, so a blower or compressed air tank is generally used to blow away the dust. Note: When blowing, the blowing port cannot be blown vertically, and the blowing port needs to be blown obliquely along the edge of the lens.
Moderate trace
Generally, there will be some stains or fingerprints on the lens, these can not be blown away, here are the following methods to clean up. (Note: The cleaning agent must use the cleaning agent allowed by the coating of the lens to prevent it from corroding the coating.)
A) Brush and pliers cleaning method
Use the small brush shown in Figure 1, soak the cleaning agent, and keep it parallel to the lens, gently brush the surface of the optical lens, and repeat until the optical lens is completely clean. It is recommended to use a new small brush every time you wipe.
If there is no professional small brush, another way is to fold the lens paper, taking care not to touch the lens paper that will contact the optical lens. The width of the fold should be similar to the width of the optical lens. Clamp the lens paper with pliers, and let the folded part soak the cleaner and keep it parallel to the lens. Gently brush the surface of the optical lens and repeat until the optical lens is completely clean. It is recommended to use new lens paper every time you wipe.
B) Dust-free cotton swab cleaning method
Generally, use imported dust-free cotton swabs and moisten them with detergent. Pay attention to ensure that the amount of detergent is not too much. Then click into the center of the lens, rotate it clockwise a little bit to move to the outside to wipe. Note: The movement cannot be wiped back and forth when wiping.
For the above two methods, please note that after wiping, you need to use a compressed air tank or blow a balloon, blow the lens several times, and then observe the surface of the optical lens to confirm the cleanliness of the lens. If there are residual stains, repeat the above steps until the optical lens is completely clean.
Note: The above method does not include the cleaning method that needs to remove the protective lens. Such as drip and drag removal method, lens paper cleaning method, etc.
Heavy pollution
Generally, when there are grease and other difficult-to-clean stains on the lens, an immersion cleaning method is required.
Other matters needing attention:
1) During the operation, you need to be careful, and be sure not to let hard objects touch the polished surface of the lens.
2) When cleaning the lens, you must first confirm that the cleaning agent cannot corrode the lens coating.
3) When using the laser, when the jumper head end cap is removed or covered, the direction of the jumper head port is tilted downward.
4) When the laser is not used, be sure to bring the jumper cap attached by Raycus.
