Optics - Lenses

The 0170937200 is a type of achromatic lens, designed to maximize the wavelength of light. This type of lens has two components, a crown glass element with a positive refractive index, and a flint glass element with a negative refractive index. This combination reduces chromatic aberration (the difference between two colors of light passing through the lens) and ensures that the resulting image is sharp.

The 0170937200 lens has an f - 20mm focus, as well as a 30mm clear aperture. This makes the lens suitable for a wide range of applications, from microscopes to digital cameras to telescopes. The lens uses a three-piece mounting system in order to mount it securely onto an optical device, usually through a filter thread or the standard photographic lens mount.

When light passes through the lens it is refracted by the two components, the crown glass and the flint glass. The crown glass element refracts the longer wavelengths of light more than the shorter wavelengths, while the flint glass element does the opposite. This reduces the difference in refigious in the two components, leading to a clear, sharp image.

The 0170937200 lens also has a built-in iris diaphragm which helps to control the amount of light entering the lens. This can be used to adjust exposure and depth of field. The aperture size can be manually adjusted by rotating the lens, and this affects both focus and f-stop. The lens also has a focusing ring so that the user can adjust the focus.

The 0170937200 lens is ideal for use in a range of applications, including photography, microscopy, telescopy, surveillance, and industrial imaging. due to its high quality, adjustable iris diaphragm, and focusing ring. The lens is also easy to mount onto an optical device, and can be used with many different cameras and telescopes. This makes it a great choice for anyone interested in capturing high quality images.

The 0170937200 lens is a great choice for anyone who wants to capture images with a high degree of accuracy and clarity. Its two elements, the crown and flint glass, reduce chromatic aberration and provide a sharper image. Additionally, its adjustable iris diaphragm and focusing ring allow users to control the amount of light entering the lens and adjust focus. Its wide range of applications, from microscopy to photography, make it a versatile lens that is perfect for almost any imaging task.
