Nowadays technical possibilities and decreasing pixel sizes – even for color sensors – require higher demands to broadband color correction of machine vision lenses.
Therefore we redesigned two of our most successful series of telecentric lenses to improve color correction for high precision measurement applications with white illumination and high resolution color sensors.
Selected lenses for ½‘‘, 1/1.8‘‘, 2/3‘‘ and 1‘‘ sensors, based on the series Correctal T85 and Correctal T120, are offered in a special „Color“ version.
The central issue of the new design is the reduction of the lateral color error to increase the spatial resolution for a broadband wavelength region. Additionally, the lenses S5LPJ6125 and S5LPJ1725 are bi-telecentric to enable use in spectrometer and prism based multi sensor cameras. Please be aware, that chromatic focus shift of camera prism will affect the resolution for multi-sensor cameras.
