Aspheric condenser lens is a single lens for collection and condensing, which the radius of curvature of one side is changed according to the height from the optical axis to minimize spherical aberration. The other side is plano or convex.
Sep 22, 2014· This is the first video documenting the conversion of a 3D Maglite from an incandescent bulb to a Cree MT-G2 LED using an aspheric condenser lens to focus the light.
When choosing an aspheric lens for collimation of a laser diode, the first step is to determine the numerical aperture of the diode. This value is given by the sine of the largest FWHM divergence angle of the laser light. Then, an aspheric lens should be chosen that has roughly twice the numerical aperture of the laser.
Aspheric condenser Lenses Steep aspheric lens surfaces produce large angles of refraction and hence short focal lengths. Aspheric lens surfaces can also be free from spherical aberration. For these reasons aspheric lenses produce highly efficient low f/number light condensers.
The aspheric condenser lens surface is precision molded, while the plano or spherical surface is ground and polished. Ideal for light collection, projection, illumination, detection, and condensing applications. Aspheric lens surface reduces spherical aberration. Higher NA than spherical lenses. Ideal for condensing and light collection.
The Aspheric Condenser Lenses page shows two condenser lenses with curved faces toward each other. As I look at your picture, I see collimated light to the left and to the right of the pair (external to the pair) and light focused to a point between the pair.
Jan 14, 2009· Aspheric lenses—those de-signed to avoid adding positive spherical aberration to an optical system—are in wide use in today's world. You can find them in telescopes, cameras, many spectacles and in the optical equipment in most ophthalmology offices and operating rooms.

Several are thermally toughened to withstand high temperatures. Their large apertures allow very efficient light collection. The steeply-curved aspheric surface is moulded and fire-polished; the second surface, facing the source, is ground and polished (except 22 AF 21 which is fire polished on both sides).
