In 1970, the company created optical fiber, a highly pure optical glass, as thin as a strand of human hair, that could transmit light signals over long distances.
The human eye is an organ which reacts to light for several purposes. As a conscious sense organ, the eye allows vision. Rod and cone cells in the retina allow conscious light perception and vision including color differentiation and the perception of depth. The human eye can distinguish about 10 million colors. [3]

Kohl is an eye cosmetic, traditionally made by crushing stibnite (antimony sulfide) for use similar to that of charcoal in mascara. It is widely used throughout the Arabian culture, typically as eyeliner to contour or darken the eyelids. Several studies have questioned the safety of kohl due to the dangers of lead poisoning. Importing kohl into ...
ZBLAN glass has a broad optical transmission window extending from 0.22 micrometers in the UV to 7 micrometers in the infrared. ZBLAN has low refractive index (about 1.5), a relatively low glass transition temperature ( T g ) of 260–300 °C, low dispersion and a low and negative temperature dependence of refractive index dn / dT .
Optical glass refers to a quality of glass suitable for the manufacture of optical systems such as optical lenses, prisms or mirrors.Unlike window glass or crystal, whose formula is adapted to the desired aesthetic effect, optical glass contains additives designed to modify certain optical or mechanical properties of the glass: refractive index, dispersion, transmittance, thermal expansion and ...
