Injection molding seemed easy—until I tried machining a double convex lens mold. From surface finish to mold alignment, this “simple” project got real fast.

In recent research published in Optics & Laser Technology and Infrared Physics & Technology, a research team led by Prof.

The schematic of the plano-convex lens (working lens). Figure 2 ... Prior to the X-Y alignment, the autocollimator is brought into optical path to double check the tip-tilt of the lens. Align X-Y ...

Infrared contact lenses using nanoparticles convert near-infrared (800–1600 nm) into visible light, enabling users to perceive infrared wavelengths without external power.

The type of image formed by a convex lens depends on the lens used and the distance from the object to the lens. 2. Draw a ray from the top of the object to the lens that is parallel to the ...

If you continue to have this issue please contact [email protected]. The lenses decrease higher-order aberrations via personalized inverse aberrations applied to the lens. Lens fit is ...

New lenses turn invisible infrared light into visible images, a study found. Humans can now see in the dark -- and even with their eyes closed -- using nanotechnology contact lenses that turn ...

Researchers say the infrared lenses may also help people with color blindness Cara Lynn Shultz is a writer-reporter at PEOPLE. Her work has previously appeared in Billboard and Reader's Digest.
