Albert Bouwers

[4] He obtained his Ph.D. from Utrecht University in 1924, with a dissertation entitled in Dutch Over het meten der intensiteit van Röntgenstralen.

[7] The design used a photosensitive layer of cesium and antimony in a cathode-ray tube, to brighten images by over 1,000 times.

[7] In August 1940[8] Albert Bouwers built a prototype for a design for a wide field concentric meniscus telescope[8] (patented February 1941) similar to, and slightly predating, Russian optician Dmitri Dmitrievich Maksutov's 1941 Maksutov telescope.

Like the Schmidt camera, the meniscus telescope has the aperture stop coincide with the center of curvature.

[1][2] Bouwers came up with a later design that used a cemented doublet to form the meniscus corrector shell to correct chromatic aberration.
