    Application of far field correction objective lens and barrel lens


    A barrel lens must be used to image the far-field correction objective. The application advantage of far-field correction objective lens and barrel lens is to leave enough space between them, so as to allow other optical elements to enter the system, such as filter or beam splitting lens. The distance (L) between the objective lens and the barrel lens is variable, but this will affect the size of the imaging area( Φ), Equations 1 and 2 below define Φ And L.

    ∅ 1 (mm) = exit pupil of objective lens

    ∅ 2 (mm) = diameter of lens barrel into pupil

    Focal length (F1) = objective lens

    F2 (mm) = focal length of lens barrel

    Na = numerical aperture of objective lens

    example:

    Using M plan apo 10x objective lens (#46-144), MT-1 barrel lens (#54-774) and 2 / 3 "camera, what is the maximum space of objective lens and barrel lens without vignetting?

    The objective lens focal length (F1) is 20 mm and the numerical aperture is 0.28, so that the exit pupil diameter:


    The diagonal of the 2 / 3 "sensor is 11mm, so Φ The minimum value is 11mm, the focal length of MT-1 barrel lens is 200mm, and its entrance pupil diameter is 24mm. Therefore,

    In this way, as long as the distance between the objective lens and the barrel lens is less than 232.7mm, there will be no vignetting.
