SPA™ Low-NA

asphericon's standard-line SPA™ Low-NA are ideally suited for light collection and laser applications. All SPAs are available in a focal length-diameter-ratio (f/d) of 2.0.

By use of a low dispersion material our SPA™ Low-NA aspheres decrease the chromatic aberration. For diameters larger than 15mm the Corrected Transmitted Wavefront is typically 20-50 times better than for moulded lenses.

Further technical details (Zemax® -data) can be downloaded on the right-hand side.

All SPA™ Low-NA aspheres are generally available off-the-shelf in two quality levels („Standard“ or „Ultra“).
