The exiting ray of the center wavelength is thus not only undeviated from the incident ray, but also experiences no translation ( i . e . transverse displacement or offset ) away from the incident ray's path.

Many lenses that have been specially optimized for digital SLR cameras are nearly telecentric on the image side, to avoid the vignetting and color crosstalk that occur in color filter array-based digital image sensors with oblique incident rays.

The inner hypotenuse shows the path of an incident ray and the outer hypotenuse shows an extension of the path of the refracted ray if the incident ray met a crystal whose face is vertical at the point where the two hypotenuses intersect.

Diffraction gratings are constructed such that the angle of the incident ray, " ? i ", is related to the angle of the " m " th outgoing ray, " ? m ", by the expression
17.
The factor multiplying n _-is the sine of angle of the incident ray with the " x " axis, and the factor multiplying n _ + is the sine of angle of the refracted ray with the " x " axis.

In vector form, if "'i "'is a unit vector pointing in the direction of the incident ray and "'n "'is the unit normal to the surface, the direction "'r "'of the refracted ray is given by:
19.
:You didn't say what article you're talking about, but in any case, the ray will only emerge parallel to the incident ray if the angles of bending are exactly opposite when it enters and leaves the glass, which will only happen if the glass surfaces are parallel on both sides.
20.
In anisotropic media such as some crystals, birefringence may split the refracted ray into two rays, the " ordinary " or " o "-ray which follows Snell's law, and the other " extraordinary " or " e "-ray which may not be co-planar with the incident ray.
