4 Positive Cylindrical Lenses Size, PCL-1-A PCL-1-B PCL-1-C PCL-1-D PCL-1-E PCL-1-F Related products and accessories Plano-Convex Lenses (PCX) Cylindrical lenses with positive focal length condense light in one dimension only. They are used to focus light to a thin line for effective harmonic generation in nonlinear crystals, in laser scanners, spectroscopy, dye lasers, acousto-optics or other applications. They are also irreplaceable for circularization of diode laser outputs, energy collection for linear detectors or for coupling to a slit input.

6 Powell Lenses Fan angle, deg Laser beam width, The Powell lens has an advantage over cylindrical lenses because later one produces a poorly illuminated line, limited by the non-uniform Gaussian laser beam. Huge spherical aberration redistribute light along the line, decreasing the light in the central area while increasing the light intensity at the line s end. The outcome is uniformly illuminated line used in all manner of machine vision applications.

7 Achromatic Lenses Cemented achromatic duplet lenses are optimized to provide excellent chromatic and spherical aberrations free performance. Optimized composition of two lenses, where one is made of dense flint and second of crown glass, assures much tighter focus than singlet spherical lenses due to minimized longitudinal and transverse spherical aberrations. They also feature nearly constant focal length across wide range of wavelengths. Standard achromatic duplet lenses cover two ranges visible (400 nm 700 nm) and near infrared (700 nm 1050 nm). Single line, dual line and different than standard broadband configurations are also available. If you do not have design or drawing of required achromatic lens, Altechna engineers will help you to make one.
