NEWBURYPORT — Like a long-awaited Christmas present, volunteers and staff at the Custom House Maritime Museum spent some of Thursday morning carefully unwrapping a $400,000 Fresnel lens once used to ...

Illumination for line-scan machine vision systems is required to produce a highly asymmetric elliptical beam pattern, to maximize system speed and accuracy. The use of LED emitters with symmetric ...

Using Ansys Zemax OpticStudio, a collimation and focusing optical system is designed for a laser diode based on standard lenses (ACL12708U-A, with f = 8 mm and d = 12.7 mm, and AL1225-A, with f = 25 ...

The 3rd order Fresnel lens in the Au Sable Light Station appears to glow orange in as it refracts the light from the sunrise near Grand Marais, Mich., in Pictured Rocks National Lakeshore.

Fresnel lenses, however, don’t require curvature of any kind, but instead utilize concentric flat rings to diffract light, with the rings’ size and width determining the overall lens focal length.

The new lens is made up of concentric rings of tungsten disulphide, which absorbs red light that hits it and re-emits it into a focal point 1 mm (0.04 in) away from the surface.

Visteon has been granted a patent for a light source system designed for medical or industrial applications, such as endoscopes. The system includes LED light sources, Fresnel lenses ...
