1 Fixed Magnification Series -High Resolution 5M Series High-resolution models that possess the best contrast and NA of all Series. Image acquisition with even higher image quality is realized by combining these lenses with cameras with a high number of pixels, especially emerging 5 megapixel sensors. Highest image quality model of the s Series. Supports 5 million pixels (3.3μm/pixel) * Except for -HR65DVI-5M Fixed Magnification Series -HR 5M Use of internal reflection light-scattering design and noise reduction filter for hot spot reduction Variable iris available for most models Very low distortion Model Magnification WD Resolution Depth Of Field NA *Information in this catalog is given for condition when the aperture is open Effective TV Distortion Largest Compatible CCD 3-HR65D-5M.3x 65.mm 5.µm 6.2mm.2.2% 2/3 22 A HR65-5M.3x 65.mm 5.µm 6.2mm.2.2% 2/3" 98 A-33 5-HR65DVI-5M.5x 65.3mm 9.3µm~µm 2.2mm~9.8mm.36~.8 ~3.6.% 2/3" 2 A-33 5-HR65VI-5M.5x 65.3mm 9.3µm~µm 2.2mm~9.8mm.36~.8 ~3.6.% 2/3" 2 A-3 -HR65DVI-5M x 65mm.µm~9µm.56mm~2.2mm.~.8 ~28.9% 2/3" A-338 -HR65VI-5M x 65mm.µm~9µm.56mm~2.2mm.~.8 ~28.9% 2/3" 35 A-3 2-HR65DVI-5M 2x 65mm 2.µm~5µm.mm~.9mm.39~.22 ~5.6% 2/3" 2 A HR65VI-5M 2x 65mm 2.µm~5µm.mm~.9mm.39~.22 ~5.6% 2/3" 9 A-32 3-HR65DVI-5M 3x 65mm 2.µm~.5µm.85mm~.2mm.5~ ~.5.% 2/3" 28 A HR65VI-5M 3x 65mm 2.µm~.5µm.85mm~.2mm.5~ ~.5.% 2/3" 25 A-358 -HR65DVI-5M x 65mm 2µm~8.2µm.6mm~.2mm.6~. 2.~8.6.% 2/3" 29 A-35 -HR65VI-5M x 65mm 2µm~8.2µm.6mm~.2mm.6~. 2.~8.6.% 2/3" 285 A-359 -HRD-5M.x mm 9.2µm 6.mm.8.% 2/3" A HRD-5M.3x mm 5.µm 6.2mm.2.3% 2/3" 22 A HR-5M.3x mm 5.µm 6.2mm.2.3% 2/3" 29 A-336 Weight (g) Mount Product Code L-3

Extremely Low Distortion The pursuit of high resolution with no aberration has resulted in the elimination of image bending. This means that it is no longer necessary to consider distortion offsets. High improvement has enabled image recognition with greater emphasis on the black and white shading. By converting the resolution chart image to binary form and then graphing and comparing the brightness levels, the -HR greatly emphasizes the difference in brightness between black and white object features when compared to our prior Mega.

The ST and HR Series solve this problem through a hot spot reduction technique that vastly reduces the reflection from the lens.

The -ST/HR brightness graph shows a reduction in the variation between the brightness in the center and periphery of the FOV which can also be seen in the sample images.

5 Illumination Uniformity For object recognition on a matte surface with coaxial illumination, only a small amount of light is reflected from the surface requiring the coaxial light intensity to be increased. When this is done, however, the brightness in the center of the image increases due to reflection in the coaxial illumination lensing. The ST and HR Series solve this problem through a hot spot reduction technique that vastly reduces the reflection from the lens. This improves the uniformity of coaxial illumination for even matte surfaces. Below, OCR using coaxial illumination was performed on a rough, microcomputer chip surface. The -ST/HR brightness graph shows a reduction in the variation between the brightness in the center and periphery of the FOV which can also be seen in the sample images.
