Caltech scientists have found a fast and efficient way to add up large numbers of Feynman diagrams, the simple drawings physicists use to represent particle interactions. The new method has ...

The TRK-1P features a complete Auto Alignment system, combined with an Auto Refractometer, Keratometer, Non-Contact Tonometer and Pachymeter. Kerato-Refractometer, Non-Contact Tonometer and ...

The PARK 1 combines a non-contact pachymeter, auto-refractometer and keratometer in one unit. In addition to the objective refraction, the keratometer values and the pachymetry can be determined ...

The human muscular system is complex and has many functions in the body, like mobility and stability. Learn more about the muscular system here.

Find out how you can change a circuit by adding items like switches with this Bitesiz KS2 science animation and a fun activity.

In this work a new multiparameter sensor platform based on lossy mode resonances is presented. The structure consists of a soda-lime optical slab waveguide butt-coupled to multimode optical fibers. A ...

A kind of biconically-tapered optical fiber (BTOF) modified by silica nanospheres is proposed to implement detection of refractive index (RI), especially low RI, with strong nonlinearity and enhanced ...
