Lens coatings are primarily designed to minimize light loss due to reflection at the lens-air interface, thereby increasing the amount of light reaching the camera's sensor or film.

Anti-reflection coatings, also known as anti-glare coatings, are designed to minimize reflections from the lens surfaces, reducing stray light and enhancing image contrast.

Anti-reflection coatings work by creating a thin layer of material on the lens surface that causes destructive interference between reflected light waves, effectively canceling them out and reducing reflections.

Multi-layer lens coatings provide better light transmission compared to single-layer coatings by reducing reflections across a broader range of wavelengths, resulting in improved image quality and reduced lens flare.

UV-protective coatings are applied to lenses to absorb or reflect ultraviolet radiation, preventing it from reaching the camera's sensor or film and causing image degradation or discoloration.

Polarizing lens coatings selectively block certain wavelengths of light, particularly those responsible for glare and reflections, resulting in reduced glare and improved image clarity.

IR-blocking lens coatings are designed to prevent infrared radiation from reaching the camera's sensor, as IR radiation can interfere with the visible light spectrum and cause image distortion or color shifts.

Flare-reducing coatings are specifically designed to minimize lens flare, which is caused by stray light reflecting off internal lens elements and creating unwanted artifacts in the image.

Nano-structured lens coatings utilize advanced nanotechnology to create coatings with enhanced anti-reflection properties, resulting in improved light transmission and reduced reflections.

Hard coatings are applied to lenses to increase their durability and resistance to scratches and abrasions, protecting the lens from damage and wear.

Hydrophobic lens coatings repel water and oil, preventing them from adhering to the lens surface, making the lens easier to clean and maintain.

Anti-ghosting coatings are designed to minimize ghosting and internal reflections within the lens, which can cause unwanted artifacts and reduce image quality.

Oleophobic lens coatings repel fingerprints, smudges, and other oily substances, making the lens easier to clean and maintain, reducing the need for frequent cleaning.

Resolution-enhancing lens coatings are designed to improve the lens's sharpness and resolution by reducing optical aberrations and enhancing the overall image quality.

Water-repellent lens coatings repel water droplets, allowing photographers to continue shooting in rain or snow without worrying about water droplets obscuring the lens and affecting image quality.
