Bottom optical Lens Hood/Lens Shade from China

In photography, a lens hood or lens shade is a device used on the end of a lens
to block the sun or other light source in order to prevent glare and lens
The geometry of the lens hood can vary from a plain cylindrical or conical
section (much like a lamp shade) to a more complex shape, sometimes called a
petal, tulip, or flower hood. These more complex shapes of lens hood take into
account the final image's shape and aspect ratio.[3] This allows the lens hood
to block stray light with the higher portions of the lens hood, while allowing
more light into the corners of the image through the lowered portions of the
hood, thereby reducing the amount of vignetting in the final image.
Ideally, lens hoods should increase in length, and therefore in efficiency, as
the focal length of the lens increases and the angle of view reduces. Lens
hoods are more prominent in long focus lenses because they have a smaller
viewing angle than that of wide-angle lenses. For wide angle lenses, the length
of the hood (away from the end of the lens) cannot be as long as those for
telephoto lenses, as a longer hood would enter the wider field of view of the
VY Optics could manufacture varied size of lens hood or lens shade,picture
