Transmission over a limited wavelength range, with moderate to high blocking out of band. Used for fluorescence, Raman spectroscopy, and laser line clean-up. • Up to 60% minimum transmission over 1.5-70 nm • OD 3 extended blocking • Lower power
Used to condense light in one dimension only. Positive cylindrical lenses can focus input collimated light to a line, transform a point of light to a line image or change the aspect ratio of an image. Useful for laser line focusing, laser projection, anamorphic beam shaping, and illumination of slit and line detector arrays.
Used with monochromatic light to generate the minimum focal spot size by eliminating coma and spherical aberrations. Diffraction-limited performance. Ideal for nonlinear optics, laser beam expansion and collimation, interferometers, materials processing, and fiber optic coupling.
Used to expand light in one dimension only. Negative cylindrical lenses diverge input collimated light away from a line. Useful for laser line generation, anamorphic beam shaping, and one-dimensional compression of images.
