Field lens
In imaging optics, a field lens is a positive-powered lens or group of lenses that comes after the objective lens
serving to change the size of the image[1][2] or to provide image-space telecentricity. It is used for the reductio
high optical gain factor, it can correct aberrations through its several elements.[3] Optical systems that fea
potential problem, which involves the inability on the part of succeeding relay lenses to capture a cone of light
lens - by behaving as a variably angled lens - solves this problem by bending or refracting the cone of light back
In X-Ray microscopy, the field lens is used to produce parallel and homogeneous illumination of the stencil.[5]
