Achromatic Telecentric Scan Lens TFS-1064-650-60-163
With CCD camera been equipped into laser scanning system, Achromatic scan lens is developed to colour correct different wavelengths. The focal length, working distance and focus spot are identially for both laser working wavelength and visible wavelength, it will help CCD to capture the actual image through F-theta scan lens, generally low dispersion crown glass and high dispersion flint glass are jointly used to correct the chromatic aberration.
