Designed for mega pixel camera that is 4.65um/pixel.
Good uniformed coaxial illumination for the F.O.V. by eliminating of the hot spot.
will show the real imaging power in high-end inspection and alignment applications.
SPO have lined up according to W.D and magnification which can support up to 2/3” camera.
There are various magnifications and working distance with low distortion design and high resolution & contrast over the full F.O.V.
F/# is related to the theoretical resolution and D.O.F & N.A of the lens directly. Thus it have to be keep the optical theory. (See the glossary)
