25mm Dia x 25mm FL Acylinder Lens, Uncoated

Product Details Diffraction Limited Design Ideal for Creating Thin Line Profiles of Monochromatic Light Sources Focus Light in Single Dimension TECHSPEC Acylinder Lenses are similar to aspheric lenses in that they provide diffraction-limited focusing performance in only one dimension. By reducing spherical aberration along the focusing axis, TECHSPEC Acylinder Lenses are ideal for creating thin line profiles. Compared to standard cylinder lenses, TECHSPEC Acylinder Lenses also dramatically reduce the spot size of monochromatic light sources to provide sharp, thin lines.
