TAMRON
2.5μm-Pixel-Pitch Sensor
By supporting a 2.5μm-pixel-pitch, the lens maintains high-resolution from center to periphery. This lens series offers superior optical performance with resolution in the mega-pixel range even in the periphery of the image, and can be used for various applications such as inspection of small component, and inspection of detailed particles. In addition, each lens in the series provides high-quality images with minimized distortion.
Shortened MOD
The Minimum Objact Distance(MOD) is 10cm for f=6, 8, 12, 16,25mm and 15cm for f=35 and 50mm lens. Thanks to the reduced minimum focus distance, troublesome use of extension ring can be reduced. Even with high-resolution 2.5m-pixel-pitch sensor size, the lens pitch sensor size, the lens provides close-up ability.
Detailed Focus Adjustment
Newly designed mechanics enable a larger rotation angle for the focus making detailed focus adjustments that are necessary for higher resolution easy.
