How do I clean optics properly? A guide for optics and laser manufacturers

Precision and cleanliness are crucial in the optics and laser industries. Improper cleaning can result in burnt optics and significantly affect the performance of your equipment. In this article, you'll learn how to professionally clean your valuable optical components and thus extend their lifespan.

The basics of optical cleaning

Cleaning optics requires care and the right equipment. Always use compressed air to remove loose dust before you start wet cleaning. High-purity isopropyl alcohol or special lens cleaner combined with lint-free lens wipes are suitable for further cleaning. For stubborn stains, a mild soap solution can be used, followed by a thorough rinse with distilled water.

Note: Never use acetone on plastic optics or housings as this can cause irreparable damage.

Cleaning techniques for optical components

Lenses and filters require special care. Clean them with circular movements from the inside out to effectively remove dirt

mirrors: Particular care should be taken here, as their coatings are often sensitive. Use gentle pressure here and avoid rubbing the same area repeatedly. For diffraction gratings and wire-grid polarization filters, the use of compressed air is the only recommended method. Any direct contact could damage the sensitive surface structure and impair the function.

Cleaning in laser assembly

In laser assembly, even the smallest dirt particles can lead to significant problems. Contamination can scatter or absorb the laser beam, which can result in loss of power or even damage to the optics. Regular and correct cleaning is therefore essential to ensure the precision and reliability of your laser equipment. Nordair Systems offers specialized cleanroom solutions that create a contamination-free environment for handling and cleaning sensitive optical components. Our laminar flow boxes, cleanroom tents and cleanroom cabins ensure a low-particle atmosphere, which is essential for professional maintenance of high-performance optics.

Conclusion

The correct cleaning of optics is a decisive factor for the performance and durability of your optical and laser components. By using the right techniques and using appropriate cleanroom environments, you can significantly improve the quality of your products and avoid costly damage.
