An imaging technique combining spectroscopy with high-resolution microscopy to produce rapid, precise measurements of quantum behavior in an atomic clock has been developed. Physicists believe the technique could improve atomic clock precision and provide a path toward measuring many-body interactions and testing fundamental physics. This is artwork made with JILA’s new imaging technique, which rapidly and precisely measures quantum behavior in an atomic clock. The images are false-color representations of atoms detected in the ground state (blue) or excited state (red). The white...Read full articleRelated content from Photonics MediaARTICLESOptical Clock Uses Laser Tweezers to Manipulate AtomsJILA physicists have demonstrated a new atomic clock design that uses laser tweezers to trap, control, and isolate atoms.

A typical optical delay line consists of a retroreflector or folding mirrors on...Photonics HandbookAspheric Lenses: Design Considerations: This first of two articles will cover design and manufacturing options for aspheres; the second will include more detail on manufacturing and testing processes. These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookFlat Optics: Considerations When Buying: To simplify the process when purchasing flat optics, we will discuss the top six factors from a manufacturer’s perspective, all of which affect the three major areas of the purchasing decision: quality, delivery and cost.Flat optics generally perform three main functions: They transmit light (windows), reflect light (mirrors) and fold light (prisms). While most optical manufacturers make spherical and flat optics, a...Photonics HandbookUnderstanding Surface Quality: A Practical Guide: Surface quality is one of the most scrutinized specifications in the optics industry. It is critical that the suppliers and customers have a consistent approach during the inspection process. These guidelines are intended to help ease communication between suppliers and customers for better products and business.Surface quality has become one of the most poorly understood specifications in the optics industry.
