Why does the light bend as it passes from air to glass or from glass to air?
This is due to the difference in optical density.
Transmission of light through lenses is best explained by?
Difference in 'optical density' of glass and air (or other glass of co-lenses)
What is the difference between ophthalmic rough blanks and optical glass?

Definition of photo-elastic constant?
Optical glass is usually free of strain, but when mechanical or thermal stress is exerted upon it, glass shows birefringence. Stress F (Pa), optical path difference (nm) and thickness of glass d (cm) have the following relationship: In this case, proportional constant is called the photoelastic constant. It is listed in this catalogue at a unit of (nm/cm/105 Pa). The photoelastic constant is the material constant that will change by glass type. By using it, optical path difference can be computed from given stress. Internal stress can also be computed from optical path difference.
What is an optical fiber made from?
Glass, very pure glass.
Are HCS optical fibers smaller than glass optical fibers?
false!
What is inside optical fibers?
Mirrored glass
What are optical fibers made of?
Good optical fiber is made of glass, but inexpensive fiber is sometimes made of plastic.
What were the first eye-contact lenses?
The first ones were made of glass..including the power..
What has the author Francis W Glaze written?
Francis W Glaze has written: 'Optical glass at the National Bureau of Standards' -- subject(s): Optical glass
Is optical fiber ihollow or not?
The main part of an optical fiber is a glass fiber (NOT hollow) within another glass fiber of another type of glass. Both types of glass have a different index of refraction; the signal travels through the inner glass fiber.
Where to get sunglasses's glass?
You can probably get them at any optical shops.
