39-12-1A is a type of optical lens with many applications in the fields of optics and photonics. It is also known as a “pancake” lens due to its flat shape. It is made from a combination of high quality optical glass and specialized coatings to create a single optical element that can produce a wide range of optical effects.

The lens works by gathering light rays from multiple angles and focusing them onto a single point. This creates a small area of light that is strongly concentrated. The 39-12-1A lens is ideal for use in motion sensors, light meters, spectroscopy, lidar, and imaging systems. It is also often employed in optical systems that require a small field of view such as facial recognition systems and medical imaging.

The lens consists of a concave spherical lens element with a flattened top. This shape allows light from multiple angles to be collected onto the main optical axis. The curved lens surface prevents chromatic aberration and assists in the uniform distribution of light. The flattened top creates a more uniform field of view than a typical convex lens design.

The 39-12-1A lens is designed to be used with a wide variety of light sources, including LED, laser, and incandescent light sources. It is also designed to be compatible with a range of different focal lengths and wavelengths, depending on the application. The lens is designed to maintain its optical properties even when exposed to high temperatures and is also resistant to high humidity environments.

The 39-12-1A lens is available in several different sizes and shapes to meet a variety of application requirements. The lens is capable of producing a wide range of optical effects, such as increasing contrast and sharpness, reducing aberrations, and controlling the amount of light that is transmitted. The lens is also capable of producing an even field of view even when used at different focal lengths.

In conclusion, the 39-12-1A lens is a versatile optical component that has many applications in the fields of optics and photonics. It consists of a concave spherical lens element with a flattened top and provides a range of optical effects due to its particular shape and design. The lens is capable of producing an even field of view at different focal lengths, and is resistant to high temperatures and humid environments. It is ideal for use in motion sensors, light meters, spectroscopy, lidar, and imaging systems.
