The lens array which has the variable focal length lens, and the micro mirror which is controlled individuallyThe micro mirror array lens which is controlled individually (DCMAL), the micro mirror where plural is controlled individually (DCM) with from the drive part it is constituted. The ...
Diverging lenseshave negative focal lengths, so they also have negative power values. The power of a lens is defined as the power of a lens is defined as the reciprocal of the focal length. Which type of lens is negative? So we can now have an idea that a convex lens has positive pow...
A convex mirror of focal length f forms an image which is 1n times the object. The distance of the object from the mirror is View Solution Q3 A concave mirror of focal length f produces an image n times the size of the object. If the image is real, then the distance of the object...
SB,19) a man uses a concave mirror for shaving . He keeps his face at a distance of 25 cm from the mirror and gets an image which is 1.4 time enlarged.Find the focal length of the mirror.
An imaging and displaying system comprises an imaging unit for acquiring images of a treatment site of a subject, a display unit for displaying the images acquired by the imaging unit, and a unit-to-unit connecting device for detachably connecting the imaging unit and the display unit. The im...

The position and focal length of the lens, and the lengths of the tubes R7 and R9, are so determined that the paths of the axial ray from the original to the optical centre of the lens on the one hand, and from the optical centre of the lens to the diapositive copy on the other ...

This optical system has substantial positive optical power which results in a faster numerical focal ratio at the focal plane than that of the telescope alone. More sophisticated corrector lenses are utilized in compact Catadioptric telephoto camera lenses. These include the Nikon 500 mm telephoto ...
As an operation method of the focal length variable lens, the above-mentioned drive expedient, electrostatic and/or controls the position of the micro mirror electromagnetically. It is possible to raise the optical efficiency of the focal length variable lens, by arranging with the structure and ...
