Optics have a wide range of applications in the optical field. Among them, lenses are very important components of optical systems. What is the application field and working principle of 39-09-1 lens? Let\'s explore these questions in detail here.

39-09-1 lenses have a wide range of applications. It can be used for imaging in microscopy, endoscopy, telecommunication, medical, and bioscience related fields. It is an achromatic doublet lens, which is mainly used to provide an image with negligible chromatic aberration. This lens can be designed for different imaging tasks and is compatible with a variety of sources. Thanks to its excellent performance, this lens can also be used in astronomy and optical communications.

In terms of the working principle, the 39-09-1 lens is a two-element design consisting of lenses with different optical properties. The first element, known as the positive element, is made of an ultralow dispersion material, MgF2, and its purpose is to reduce chromatic aberration. The concave front surface of the positive element has a short focal length, which ensures high chromatic aberration correction. The second element, known as the negative element, is made of an optically transparent material such as N-BK7. The back surface of the negative element has a long focal length, enabling the lens to provide a broad spectrum of colors.

In addition, the 39-09-1 lens employs a two-dimensional, air-spaced design. This design enables the lens to realize a compensation of difference of diopter due to the temperature, providing more stable image quality. Moreover, the two-dimensional design ensures minimal aberration and higher image sharpness. This design also allows for a large pupil in the lens, providing a maximum aperture of F/2. These features make the lens suitable for many imaging tasks.

Thanks to its excellent features, 39-09-1 lenses are widely used in multiple fields. This kind of lens has a wide range of applications, and it provides excellent chromatic aberration correction and superior image sharpness due to its two-dimensional design.
