Cleaning method of Dongguan laser cutting machine lens

When cleaning the lens, we must be very careful in lens cleaning, considering the following matters:

1。 Be sure to pick up glasses and put on rubber gloves or fingertips, because hands with dirt and oil droplets will contaminate the lens, resulting in performance degradation.

2。 Do not use any tools, pick up the lens, such as tweezers.

3。 The lens paper should be placed to avoid damage.

4。 Do not put the lens rough or hard surface, infrared lens is easy to scratch.

5。 Pure gold or copper surface clean, do not touch.

Step gently clean contaminants (dust, fluff)

The balloon floats off the surface of the lens. If the pollutant cannot be blown off, continue with the second step. Note: do not use compressed air plants, because it contains a lot of water and oil, water will absorb harmful coating surface.

(lens and lens holder are only the first step)

Step gently clean contaminants (dust, fingerprints)

Use acetone, alcohol wet cotton swab or cotton ball to gently scrub the surface, pay attention to avoid hard scrubbing. To quickly on the surface, so that the liquid evaporates, leaving stripes.

If this step does not remove dirt, proceed to step 3.

Note: 1) and high quality cotton paper.

2) Recommended reagent grade acetone or isopropanol.

The third step is to clean the pollutants (saliva, oil drops) gently and moderately

Or swab the surface with white vinegar with cotton swab, use less force, and then wipe the excessive white vinegar with dry cotton swab. Then immediately or cotton swab dipped in acetone, gently wipe the surface, remove the residual acetic acid.

If the dirt cannot be removed in this step, continue with step 4.

Note: 1) only paper swabs can be handled

2) Use high quality surgical cotton

3) 6% acetic acid concentration is recommended

The fourth step is absolutely impossible new lens cleaning operation. The following steps are in front of the lens and are only used for very dirty lens cleaning. If the movie is deleted, the lens loses its function. The obvious color change indicates that the film has fallen off.

Step 4: strongly clean the polluted lens (splash)

These lenses are very polluted. We use polishing paste to remove these pollutants.

Polish the milkshake, pour in 4-5 drops of cotton and gently move in a round style in the lens. Don't press the cotton ball. The cotton ball has enough self-esteem. If you use too much pressure, the polish will scratch the surface. Flip the lens often in one direction to avoid over polishing. Polishing time should be controlled at 30 seconds. Any time a color change is found and polishing immediately stops, the film is described as external corrosion.

Step 4 B

A new cotton ball dipped in distilled water gently wipe the lens surface to clean, wet the lens and remove the remaining polishing paste. Be careful not to let the lens surface dry, it is difficult to remove the residual polishing paste.

Step 4 C

Quickly dip a cotton swab into the fluff of alcohol and gently clean the entire surface of the lens to remove the remaining polishing paste.

Note: if the lens diameter exceeds 2 inches, use a cotton swab instead of this step.

Step four, D

Gently wipe the lens surface with a cotton swab dipped in acetone fluff. The last remaining step is to remove the paste and polish. When the final rinse with acetone, gently wipe the lens swab, overlapping, the whole surface is straight across. When final scrubbing, slowly move the coated surface to ensure rapid drying of acetone. This eliminates the fringes on the lens surface.

The fifth step to detect and clean the lens

The final step is to carefully examine the black background on the surface of the lens in the sun. If you find any residual polishing paste, you can repeat 4b-4d until it is completely removed. Note: the type of contamination or damage is not clear, such as metal spatter, dent, etc. If you find this type of lens like pollution and damage, then you need to repair or replace a new lens.
