Managing Holography Errors in Asphere Metrology Aspheric lenses are preferred over conventional spherical lenses in many optical systems for their high optical performance and lightweight and compact form factor. However, measuring aspheric surfaces is not a straightforward process. Metrology options are typically based on interferometry or profilometry1 (Figure 1). To measure an asphere interferometrically, the reference wavefront must match...

Editorial
A turn toward brighter days It may seem counterintuitive to plan a cover feature on solar imaging for the December issue, which will be distributed just weeks before the winter solstice, but what better emblem to invoke brighter days ahead. The COVID-19 pandemic has made a tumultuous year even more difficult. It has brought tragedy and trauma for families, and some variation of Hobson’s choice for business and industry....
Lasers In Use
Durable Optical Coatings Help to Advance Laser Safety Today, lasers can be found in a multitude of applications ranging from laser pointers for classroom instruction to medical instruments for eye and cosmetic surgery. Lasers are also used for research, materials processing, defense, and flight safety. Because of the high power densities that lasers achieve, they pose a serious risk to eyes and skin. Depending on variables such as wavelength,...
