Telephoto lens has a narrower angle of view,it thus gives apparent magnification to objects,it also seems to compress distant things, and there is less depth of field. The most obvious is to allow photographs of distant organisms to be made. Specification of our telephoto lens as follow:...

Wide angle lenses are great for capturing the expanse of a mountain view, or for giving one an appreciation of the entirety of an organism's habitate. Specification of our wide angle lens as follow: 25mm 0.45X wide angle lens 27mm 0.45X wide angle lens 28mm 0.45X wide angle lens 30mm,30.5mm,34mm,37mm,43mm,46mm,49mm,52mm,55mm,58mm,62mm,72mm...

Fisheye lens distorts straight lines into ridiculous curves. Straight lines, depending on where they are in the photo can be pulled a lot, a little, or not at all. The farther they are from the the center line of the photo, the more distortion there is. The closer the line is to the midpoint of the X or Y axis of the lens, the straighter the line...

Beamsplitter Cube is a more sophisticated type consisting of two right- angle prisms cemented together at their hypotenuse faces. The cemented face of one prism is coated. Before cementing, with a metallic or dielectric layer having the desired reflecting properties, both in the percentage of reflection and the desired color. The absorption loss...

Cylindrical lens is used to correct astigmatism in the eye, and, in rangefinders, to produce astigmatism, stretching a point of light into a line.They are available in either plano concave or plano convex configurations. Plano-Concave Cylindrical lenses have a negative focal length and are used for image reduction or to spread light. Plano-Convex...

Waveplates (retardation plates or phase shifters) are made from materials which exhibit birefringence. The velocites of the extraordinary and ordinary rays through the birefringent material varies inversely with their refractive indices. This difference in velocities gives rise to a phase difference when the two beams recombine. In the case of an...
