has introduced its TechSpec plastic hybrid acylinder lenses. Similar to aspheric and cylinder lenses, they provide diffraction-limited focusing performance in only one dimension. Designed at 587.6 nm, they are suitable for use in the visible wavelengths. The lenses reduce spherical aberration along the focusing axis for creating precise thin-line profiles with broadband sources. The hybrid lens design offers negative optical dispersion and good color correction. The lenses feature a high numerical aperture, enabling their use with divergent light sources such as laser diode bars and LEDs. They are available with a 25-mm diameter in focal lengths of 20, 25, 30, 40 and 50 mm for ease of integration into a variety of applications. They are offered either uncoated or with a visible coating.
