The theoretic value of the focal length calculation serves to find the best suitable optics.

Machine vision focal length. Vs 085 series fixed focal length lenses with f085 for high speed cameras the brightest fixed focal length lenses in the machine vision market. The calculators below will help you determine the lens focal length you need. Compact fixed focal length lenses which offer a small physical size are ideal for automated machine vision applications. It is more flexible and is smart enough to suggest specific. Edmund optics offers a wide variety of fixed focal length lenses and c mount lenses in a range of sizes anti reflection coatings sensor coverage resolving powers mtf focal lengths or working distances. I am trying to choose a camera and lens for my imaging system. The camera lenses sold here are specifically designed to be used with 12 23 1 43 or 35 mm sensor format cameras and are well suited for machine vision applications. I know the following about the real life situation. Calculating camera sensor resolution and lens focal length. It is assumed the cameras sensor has a 43 aspect ratio the sensor is a common size and that you will use all the pixels. Or try our new machine vision lens calculator instead. Sv egg box series fixed focal length macro lens kit for testing for machine vision applications in a laboratory or factory. Long working distances allow for integration into machine vision measurement systems compact design and long parfocal length simplifies mounting tube available for use with c mount cameras. How do i make sure that i have the correct lens focal length and image sensor resolution. Standard lenses feature a 50 mm focal length and their picture angle most closely approximates the view of a human eye.

Thorlabs offers lenses with fixed focal length ie prime lenses that offer superior optical performance at focal le. As technology and mobility continue to drive machine vision application techniques from industrial to commercial no longer are fixed focal length lenses with manual irises the only solutions used by the professional. By focusing the lens for different working distances differently sized fields of view fov can be obtained though the viewing angle is held constant. 18 28 4 6 8 12 16. The focal length f virtually serves to calculate the required lens and is thus the most important specification to characterise an entocentric normal lens. In machine vision systems lenses are generally classified as standard wide angle telephoto zoom and telecentric each of which features different focal lengths and operational characteristics. A fixed focal length lens also known as a conventional or entocentric lens is a lens with a fixed angular field of view afov. This brief article highlights some of the more common features and functions of lenses used in machine vision. Vs wa series inner surface inspection of bottles and containers.
