*High resolution power for 1.5 million pixel
*TV distortion under 0.1%
*Design at WD 100mm-50mm for exclusively macro
*Line-up-10 models
*Minimize the difference of quantity of light between center and
corner of a lens
*Minimize the difference of the resolution power between center
and corner of a lens

The New Macro CCTV lenses are successfully designed to improve the optical distortion extremely on all of the types by optical distortion within 1% and TV distortion within 0.1% (available on 1/3 inch only on FVO420) requested in image processing. Specially, it is remarkably effective for low distortion in the wide range (low magnification) usually to be difficult to correct by which a much better image is visible as if a telecentric lens is used in comparison with the conventional CCTV lenses.
COMPARISON IN OPTICAL DISTORTION(1/2 CCD)
Conven. lens 18% FV0420 0.9%
Conven. lens 13% FV0622 0.3%

Making a point of optical design at WD 100mm-500mm most suitable for FA and Laboratory observation, successfully minimize the resolution power gap in the center and the conner in image processing on all of the lenses. Also, it is succeeded to apply for the higher resolution power such as 1.5-2 millions pixel CCD cameras which will be a major line of CCD camera for the future.

Vertical lighting adaptor, side view adaptor, and other filters extend particularly the optical performance of the lens.

	ADAPTOR FOR CO-AXIAL VERTICAL LIGHTING
	The best auxiliary attachment to check dusts and scratches on a surface of semiconductors and metals in attaching the adaptor to the top of the lens.
	ADAPTOR FOR SIDE VIEW
	In case of looking at an object placed at 90 degrees against the camera, use the side view adaptor to divert an optical path. Simply, attach the adaptor to the top of the lens.
	ADAPTOR FOR A PINHOLE LENS
	The FV lens is converted to a pinhole lens in attach the "pinhole adaptor" onto the top of the lens.
	REAR CONVERTERS
	Enlarge maginfication to 1.5x-5x with the 6 converters which are applicable for the particular purpose.
	FILTERS
	Available for the diameters of 27.5and 30.5 to meet the wave length of UV and IR etc.

Now, as symbolizeed with the Optical Stepper, the optical engineering is developing for UV and furthermore in order to apply for the "World of Micro" or more precision.
For the field of FA, a fine digital camera is coming out available for UV 365nm and grade up the high resolution to approach the possiblilities for the "World of Micro".
The FV2020UV and FV4525UV lenses have been developed specially for 365nm in materializing of the possibilities. Now,you cna see an object with FV Series Lenses which has ever been invisible with the conventional lenses.
