The delicate nature of optical components requires that special procedures be followed when handling optical components, maximizing performance and life. In daily use, Optical Components the optical components will be exposed to dust, water and skin oils and other pollutants. These contaminants increase the scattering of the optical surface and the absorption of incident light, which creates hot spots on the optical surface, Optical Components causing permanent damage. The coated optical element is particularly susceptible to such damage.
By using the appropriate processing technology, you can reduce the number of cleaning optics and improve their service life. Open the optical element in a clean, temperature controlled environment. Do not handle the optical components directly, because the skin grease will cause permanent damage to the surface of the optical components. Instead, you can operate with gloves, making it easier for smaller optics, using optical tweezers or vacuum tweezers. Optical Components Regardless of the method used to clamp the optical element, Optical Components it can only be held along the non-optical surface, such as the matte edge of the optical element.
Importance: Holographic gratings, groove gratings, first side unprotected metal mirrors, and thin film spectroscopes (which are not a detailed list) of optical surfaces must never be touched by hand or optical operating equipment. These surfaces are particularly sensitive and any physical contact can cause damage.
When inspecting the surface of the reflective coating, Optical Components the optical element needs to be held parallel to your line of sight. The optical element should intersect the line of sight, rather than perpendicular to the observed optical surface, so that contaminants can be seen instead of the reflected light. Polishing the surface, such as a lens, needs to be perpendicular to your line of sight, Optical Components so that you can check the transparency of the entire optical element.
If there is a surface defect on a clean optical surface, the size of the defect can be categorized using a scratch standard plate, that is, Optical Components comparing the dimensions of the calibrated defect on the standard disc and the size of the surface defects of the optical element. If the size of the defect on the optical surface exceeds the manufacturer's scratch specification, the optical element needs to be replaced to achieve the desired performance.
If possible, be sure to read the manufacturer's recommended cleaning and operating procedures. Since the cleaning of the optical components is all concerned with the operation of the optical components, Optical Components use the operating instructions described below in accordance with the appropriate operating procedures. If it is clean or improperly handled, it will cause permanent damage to the optical components.
Before cleaning the optical element, check the optical element to determine the type and severity of the contaminant. This inspection step can not be skipped because the cleaning process of the optical element usually involves the solvent and physical contact with the optical surface, Optical Components which may cause damage to the optical element if the treatment is too frequent.
The cleaning sequence of the optical elements adhering to a variety of contaminants is very important so that the optical surface is not destroyed by other contaminants when removing a contaminant. Optical Components For example, if an optical element is contaminated with both oil and dust, wiping the oil will scratch the optical surface. This is because the dust will rub along the surface when wiping.
