These distortion-free, colour corrected lenses were designed, among other things, for checking negatives and focusing ground glass screens. The lower, transparent acrylic insert can be replaced with the black acrylic insert included with the magnifier to prevent light entering from the side. The extremely high-quality lens can be focused. In addition to use with slides, the large field of view makes this high-quality magnifier suitable for all applications requiring a larger field of view.
