Home / Custom / Optical Components / Cylindrical Mirror / Meniscus Cylindrical Lens 
Meniscus cylindrical lens is a special type of optical lens that can converge or diverge light beams in a single dimension. Compared to ordinary cylindrical lenses, its meniscus design more effectively corrects spherical aberration, resulting in clearer and more accurate imaging, especially in systems where high spot quality is required.
