ASPHERIC LENSES
An aspheric lens or asphere is a lens whose surfaces have a profile that is neither a portion of a sphere nor of a circular cylinder. An aspherical lens is used in correcting distortion in ultra-wideangle lenses or coma in large-aperture lenses. The asphere’s more complex surface proļ¬le can eliminate spherical aberration and reduce other optical aberrations compared to a simple lens. A single aspheric lens can often replace a much more complex multi-lens system. The resulting device is smaller and lighter, and possibly cheaper than the multi-lens design.
The aspheric surface is precision molded, while the plano or spherical surface is ground and polished — ideal for light collection, projection, illumination, detection, and condensing applications.

Customer’s Remarks
“Argus has supplied quality MgF2 windows at a competitive price and with impressive turnaround times, often needed to meet critical deadlines. I have used the windows as a physical barrier, placed between a light source (with short UV wavelengths) and a target, in order to reduce or be able to quantitatively determine contamination effects.”
- Doug, BOEING Company
