HIGH RESOLUTION TELECENTRIC LENS FOR 5 MEGAPIXEL CCD

HIGH RESOLUTION LENS OPTIMIZED FOR FPD INSPECTION

Vieworks Camera Lens, VLS-N027F, VLS-T040C/VLS-T050C Vieworks Camera Lens, VLS-N027F, VLS-T040C/VLS-T050C Vieworks Camera Lens, VLS-N027F, VLS-T040C/VLS-T050C Vieworks Camera Lens, VLS-N027F, VLS-T040C/VLS-T050C

VLS-T040C/VLS-T050C

VLS-T040C/T050C lenses are designed and optimized to work with 2/3 inch format, 5 megapixel CCD cameras. VLS-T040C/T050C, object-sided telecentric lenses, can prove extremely useful in the inspection of 3D objects or scenes where image size and shape accuracy are crucial. Its compact size makes the best choice for machine vision applications involving significant space limitations.

Main Features

  • High resolving power: Enabling 5 megapixels camera
    (optical format: 2/3˝/pixel size: 3.45㎛)
    to realize the maximum performance
  • Compact design: Easy to assemble for small devices
  • Variable iris: Enabling to configure optimized
    shooting conditions
  • Optical distortion: Less than 2.0%



VLS-N027F

VLS-N027F lens is designed and optimized to work with 29 megapixel CCD cameras and sets a new standard for lens performance in high resolution metrology applications. It prevents degradation of sensitivity and brightness on the CCD equipped with a microlens. Specially, its MTF performance curves show that each R, G and B curve converges on similar results. With these unique characteristics, inspectors do not need to adjust the focusing accuracy every time the color of panel changed during inspecting defects in the flat panels.

Main Features:

  • High resolving power: Compatible with 29 megapixels area scan cameras
  • High relative illumination over 90%
  • High sensitivity
  • No shading on the sensor with a micro lens
