Thin Film Inspection Methods Aim to Match Human Eye Perception
Thin Film Inspection Methods Aim to Match Human Eye Perception
Thin-film coatings have long been ubiquitous in precision optical systems, and are now finding increasing use in eyeglasses, architectural glass and displays. When fabricating precision optics, the primary requirement is that coatings meet particular reflectance and transmittance specifications. But in consumer applications manufacturers are often concerned with the visual appearance and consistency of the coating. While instruments for quantifying coating appearance have been available for decades, legacy technologies suffer from two important limitations: as lab instruments, they are not suitable for production settings, and they often can’t accurately measure very thin glass sheets that are now finding greater use in displays.

Tube Coatings
NTFL has the expertise to coat complex shapes and we are able to coat the outside diameter of tubes with good uniformity. We can coat tubes with outside diameters ranging from 1 mm to 20 cm, and lengths from 1 mm to 50 cm in length. Most of the coatings that we manufacture for plano substrates can be applied to tubes.

Artificial Dielectric-Based Lens Enables Efficient Terahertz-Wave Control
Artificial Dielectric-Based Lens Enables Efficient Terahertz-Wave Control
Future terahertz-wave devices for communications and imaging could benefit from a lens based on artificial dielectrics. Terahertz radiation (about 100 to 10,000 GHz) is a relatively unexplored slice of the electromagnetic spectrum but it holds the promise of countless new imaging applications, as well as wireless communication networks with extremely high bandwidth.

Fish-Inspired Fractals Guide Optical Coating Design
Fish-Inspired Fractals Guide Optical Coating Design
Fish scales could serve as a model for better broadband reflectors and custom multispectral filters. "We are proposing a model that uses fractal geometry to describe the layering in the biological structure of silvery fish," said Pennsylvania State University postdoctoral researcher Jeremy Bossard. "While we are not trying to reproduce the structure found in nature, the same model could guide the design of devices such as broadband mirrors."

LZH Launches 3 Hybrid Numerical Optics Research Projects
LZH Launches 3 Hybrid Numerical Optics Research Projects
Nonprofit research institute Laser Zentrum Hannover e.V. (LZH) is working on three subprojects in the research priority, Hybrid Numerical Optics, of the Hannover Centre for Optical Technologies (HOT) at Gottfried Wilhelm Leibniz University Hannover. Working in a new competence center for optical simulation, the LZH will address subprojects in the areas of high-power glass fiber amplifiers, dielectric coatings and light propagation in fluid columns.
