TCLWD is a range of telecentric lenses specifically designed for electronic and semiconductor Automated Optical Inspection (AOI) and tool presetting machines.
All these lenses feature a working distance of 132 mm while ensuring excellent optical resolution, high telecentricity and low distortion, thus matching and even exceeding the industrial requirements for the target applications.
The long working distance allows for extra space, which is essential if you need to install illumination, pick-up tools or provide the necessary separation from hazardous production processes.
In addition to the long working distance, TCLWD optics deliver a numerical aperture large enough to take advantage of high resolution / small pixel size cameras, making these lenses a perfect match for general-purpose 2D measurement systems.
- Working distance: distance between the front end of the mechanics and the object. Set this distance within ±3% of the nominal value for maximum resolution and minimum distortion.
- Working f-number (wf/N): the real f-number of a lens in operating conditions.
- Maximum angle between chief rays and optical axis on the object side. Typical (average production) values and maximum (guaranteed) values are listed.
- Percent deviation of the real image compared to an ideal, undistorted image. Typical (average production) values and maximum (guaranteed) values are listed.
- At the borders of the field depth the image can be still used for measurement but, to get a very sharp image, only half of the nominal field depth should be considered. Pixel size used for calculation is 3.45 μm.
- Object side, calculated with the Rayleigh criterion with λ= 520 nm
- Indicates the availability of an integrated camera phase adjustment feature.
- Measured from the front end of the mechanics to the camera flange.
