Processing Of Optical Components

Dec. 27, 2019

Customized optical components manufacturer share with you: The delicate nature of optical components requires special procedures to be followed when handling optical components to maximize their performance and life. In daily use, optical components are exposed to contaminants such as dust, water, and skin oils. These pollutants increase the scattering and absorption of incident light on the optical surface, which can create hot spots on the optical surface and cause permanent damage. Coated optical components are particularly vulnerable to such damage.

Due to the different materials, dimensions, and so on of the optical components, it is very important to use the correct processing and cleaning methods. What works for one type of optical element may destroy another type of optical element. For this reason, we recommend that you read this entire article before cleaning the optics. If the optic you are using or its category is not mentioned in this article, please contact the optics manufacturer for treatment and cleaning methods.

Deal with: By using the right treatment technology, you can reduce the number of times you clean your optics and increase their life. Open the optics in a clean, temperature-controlled environment. Never handle optical components directly by hand, as skin oils can permanently damage the surface of the hyper hemisphere dome lens. Conversely, you can operate with gloves. For smaller hemisphere dome lenses, it is more convenient to use optical tweezers or vacuum tweezers. Regardless of the method used to clamp the optical component, it can only be clamped along non-optical surfaces, such as the matte edges of the optical component.

Importance: Holographic gratings, grooved gratings, unprotected metal mirrors on the first side, and optical surfaces of thin film beamsplitters (this is not an exhaustive list) must never be touched by hand or optical manipulation equipment. These surfaces are particularly sensitive and any physical contact can cause damage.

Warning: Most crystals (such as calcite, beamsplitters, lithium niobate crystals, and electro-optic modulators) are temperature sensitive and can burst when exposed to thermal shock. Therefore, make sure that the packaging and items are placed in a temperature-stable environment before opening. These crystals are more fragile than ordinary optics, so care must be taken when cleaning them.

Deposit Protection:

Never place an optical element on a hard surface, because the optical element or the contaminants on its surface will wear away the optical element. Instead, most optics should be wrapped in lens paper and stored in a storage box designed for optics. Usually, these boxes are kept in a low humidity, high cleanliness and temperature controlled environment. Optical elements are easily scratched or contaminated, and some optical coating elements are hygroscopic, so proper storage is very important to protect the optical elements.
