Cleaning Procedure For Opticsc

Dec. 31, 2019

If possible, be sure to read the cleaning procedures recommended by the manufacturer. Because the cleaning of optical components all involve the operation of optical components, please follow the corresponding operating procedures strictly when using the cleaning guidelines described below. Improper cleaning or handling can cause permanent damage to the optics.

The optical mirror supplier shares with you: Before cleaning the optical components, please check the optical components to determine the type and severity of the contaminants. This inspection step cannot be skipped, because the cleaning process of optical components usually includes solvents and physical contact with optical surfaces, which may cause damage to the optical components if handled too frequently.

The cleaning order of the optical dome with multiple pollutants attached is very important so that the optical surface is not damaged by other pollutants when one pollutant is removed. For example, if an optical component is contaminated with oil and dust at the same time, wiping the oil first will scratch the optical surface. This is because dust also rubs along the surface during wiping.

Before doing any other cleaning technique, it is usually necessary to blow away dust and other loose contaminants. This method requires the use of an inert dust gas tank or a blower. Do not blow directly with your mouth against the surface of the optical component, as it is likely to deposit saliva on the optical surface.

If you are using an inert dust-removing gas, place the gas tank upright before and throughout the use. Do not shake the gas tank before or during use. And point the nozzle far away at the optics before blowing. These steps help prevent inert gas propellants from depositing on the optical surface. If you use a filling gas, move the gas tank approximately 6 inches away from the optics and use a short blow. Rotate the nozzle of the inert gas tank so that the nozzle and the surface of the optical element form a grazing angle to blow air. For large-sized optical element surfaces, blow air on the optical surface in the following pattern.

This cleaning method is suitable for almost all types of optical components. However, for certain optical components, such as holographic gratings, scribed gratings, unprotected metal mirrors, calcite polarizers, and cylinder lenses, all may be damaged under physical contact. Wiping is the only cleaning available. method. Because this cleaning method is non-contact and solvent-free, it should be the first step in cleaning almost all optical components.

Warning: The 2 micron thick nitrocellulose membrane on the thin film beam splitter is particularly fragile and can be easily broken by air pressure on the surface. If filling air is used for these optics, the bottles need to be kept far enough to prevent damage to the film.

Warning: The polished clear surface of the calcite polarizer is very delicate, and if the gas is blown too close to its surface, it will be damaged.
