Product Family Description
- Color-Corrected Plastic Aspheres
- Diffractive Surface Minimizes Chromatic Aberration
- Low-Cost, Molded Design
TECHSPEC® Plastic Hybrid Aspheric Lenses are molded aspheric lenses with diffraction-limited designs that eliminate chromatic aberrations caused by broadband light sources. These hybrid aspheric lenses are ideal for imaging or ophthalmic applications, or for use with tunable lasers or broadband or multispectral illumination sources. The aspheric lens eliminates spherical aberration, while the diffractive surface features a negative optical dispersion to yield excellent color correction.
TECHSPEC Plastic Hybrid Aspheric Lenses are similar in performance, but offer several advantages to our TECHSPEC Aspherized Achromatic Lenses. Hybrid aspheric lenses feature all-plastic, monolithic designs that are much lighter than comparable aspherized achromatic lenses. These optical lenses are also available in higher numerical apertures. However, plastic hybrid aspheric lenses are limited by the inherent diffraction efficiency of the aspheric surface, yielding lower overall transmission than comparable aspherized achromatic lenses.
These lenses won the 2011 Prism Award for Optics and Optical Components.
