Image distance, v = – 10 cm(a) It is a virtual image because the image is formed on the same side as the object. Also, since the lens is a concave lens the image will be erect and diminished.(b) Lens formula is1 / v – 1 / u = 1 / f∴ 1 / -10 – 1 / -20 = 1 ...
Lenses are of interest for the design of directive antennas and multi-optics instruments in the microwave, terahertz and optical domains. Here, we introduce an optical problem defined as the complement of the well-known generalized Luneburg lens problem.
10. A contact lens material according to claim 9, wherein the fluorine-containing alkyl (meth)acrylate other than the fluorine-containing monomer of the formula (I) is a monomer of the formula (II), ##STR10## wherein R3is H or CH3, r is an integer of 1 to 4, s is 1 to 10,...
The ceramic phosphor plate may also be an Eu2+activated Sr—SiON having the formula (Sr1-a-bCabBac)SixNyOx:Eua, wherein a=0.002-0.2, b=0.0-0.25, c=0.0-0.25, x=1.5-2.5, y=1.5-2.5, y=1.5-2.5. The ceramic phosphor plate may also be a chemically-altered Ce:YAG phosphor that is...
But for this class level and for for what I teach, it’s supported. So I’m not going to put it up. They don’t have to factor in a high stakes exam. They have to be able to solve, but they can solve with technology, they can solve with the quadratic formula. They don’t ...

To find the focal length of a convex lens when it is immersed in water, we can use the lens maker's formula. The formula for the focal length
channel has the same focal length. However, the large number of tolerances involved in the manufacture of a lens stack array can result in the different optical channels having varying focal lengths. The combination of all the manufacturing process variations typically results in a deviation of the...
