The 39-09-3B optical element is a three-lens, precision-ground and coated optical element for the focused imaging of distant objects. It is widely used in industrial and scientific applications where high resolution imaging over long distances is required.

The 39-09-3B consists of three high precision, single coated lenses, mounted in a protective housing. The lens elements are arranged in a line and each lens element refracts the light passing through it, changing the direction and focusing the incoming light into a pattern of concentric circular rings. This pattern is then focused by the last single lens element, to form a focused, sharp image of the distant object.

The effectiveness and accuracy of the 39-09-3B are determined by the precise focusing of the individual lenses and the quality of the single coated lenses. The first single coated lens is used to collimate the incoming light, and the second single coated lens focuses and further refracts the collimated light. The third lens element then focuses the light, creating the final, focused image.

The diameter, focal length, and index of refraction of each of the individual lenses must be precisely determined and calibrated to create a precise, clear image. For example, in order to create a clear, focused image, the lenses must be arranged, so that their focal points are aligned with each other, resulting in a precise image.

The 39-09-3B lens element is used in many scientific applications, such as laser scanning and imaging of objects in a laboratory environment. The lens element is also often used to create an image of a distant object in industrial applications, such as focusing laser beams on a target, or viewing a complex manufacturing process from a distance.

The 39-09-3B is a precision-ground and coated optical element which offers superior performance in terms of resolution, image fidelity, and contrast. The 39-09-3B is used in many applications ranging from printing and film photography to imaging in aerospace, automotive, medical and other scientific applications.
