Symmetrical 4fsystem Setup a telecentric 4fimaging system with two identical planoconvex lenses made of BK7 with thickness d 10 mm and approximate focal lengths f 100 mm. The wavelength of the system is 546. 07 nm and the numerical aperture in the object space is NA 0. 2. The object has a diameter of 10 mm.Imaging: the 4F system. The 4F system (telescope with finite conjugates one focal distance to the left of the objective and one focal distance to the right of the collector, respectively) consists of a cascade of two Fourier transforms collector lens image objective lens plane 4f lens system

Physics Tools for optics Find image distance and magnification for two lens system Use this simple tool to solve physics problem related to two lens system. You can use this tool find position of the final image formed by the combination of the two lenses, and magnification of the final image formed by the combination of the two lenses.

In many publicationslectures it is said that the 4f lenses configuration is the preferred configuration for imaging. My question is why does this configuration in an imaging actually minimizes the aberration. Products& Services. Description: BU GU is the system Lens Driver corresponding tothe Microstep driving, making it possible to configure thesophisticated, high precision and low noise lens driversystem. Microstep controller is incorporated into IC, making it possible to cut down CPU power. 4f lens system Hardware implementation of the system transfer function: The 4F correlator. A transmission mask containing the FT of the second function, g ( x, y ), is placed in this same plane, one focal length behind the first lens, causing the transmission through the mask to be equal to the product, F
