How do you clean coated optics?

Only use compressed air, reagent grade alcohol or de-ionized water to clean plastic optics. If an optical coating or substrate is unknown, err on the side of caution, and use de-ionized water and mild dish soap to avoid damage to the optic by any harsh chemicals.

How do you clean fused silica?

Cleaning. The cleaning of fused quartz is critical before it is used in any application. The fused quartz should be cleaned by placing it in a 7% maximum solution of Ammonium Bifluoride for no more than ten (10) minutes, or a 10% volume maximum solution of Hydrofluoric Acid for no more than five (5) minutes.

How do you clean thorlabs mirrors?

Moisten the final folded edge with solvent and use that edge to wipe/clean the optical surface. Using a pump bottle to dispense the solvent will make it easier to hold the optic in one hand while moistening the wipe with the other. During cleaning, wear gloves or finger cots.

How do you clean ophthalmic lenses?

Steps

  1. Always remove dust first!
  2. To remove stains, use a lint-free cotton swab or a lens-cleaning tissue dipped in the optical cleaning solution.
  3. To remove stains on plastic components, use optical cleaning solution number 2 (the water-based solution).
  4. To remove fungus, use an optical fungicide.

How do you clean an optical grating?

Due to the construction of diffraction gratings, the only recommended cleaning method is to use Compressed Air or an Air Blower to remove surface dust. Avoid methods that require any direct contacting of the grating surface.

How do I clean with acetone?

If there are ugly black scuff marks on your tile, concrete, or laminate floor, just pour a couple of teaspoons of acetone onto a clean rag or paper towel, and wipe the offending marks away. Then go over the area with a clean rag dampened in water to remove any lingering acetone residue.

How do you clean Devitrification?

One method is to cover the the affected area with a layer of clear quartz and refiring. Another is using a 10% hydrofluoric acid solution to wash the quartz for several minutes at room temperature followed by a series of rinses in deionized water and quickly drying.

How do you clean telescope lenses?

You’ll need a soft, grit-free wipe. A well-washed piece of pure cotton cloth works well. Moisten it with the fluid and swirl the fluid gently across the lens, applying no pressure. If necessary, rub dry with a fresh piece very gently.

What is protected silver?

Protected Silver (PAG) Protected Silver has the highest reflectance of any protected metal coating in the visible, near IR and mid IR regions. As an external reflector, silver is overcoated with one of several transmissive materials, depending on the wavelength region of interest.

What is optical cleaner?

Optical Cleaning. Extend the lifetime of your optics with lens tissue, compressed air, or cleaning solutions designed to remove residue or debris without damaging the optical surface.

What can I substitute for acetone?

Rubbing alcohol-based products are often the best substitutes for acetone. These products include pure rubbing alcohol, hand sanitizer, deodorant, and hairspray. You can also use toothpaste or hydrogen peroxide-hot water solution instead of acetone.
