TEVIDON ® Macro series
TEVIDON ® macro lenses feature edge-to-edge high resolution and good color correction
in both the visual or the near-infrared range. The 4/45 lens is available with
a manually lockable or fixed aperture. The apertures of the 5.6/45 and 8/45 lenses
are fixed. They are all exceptionally versatile, and their low distortion makes
them the choice of preference for both imaging and machine vision applications.
TEVIDON ® macro lenses are especially recommended for CCTV applications using
1/3” to 2/3” camera formats. These four lenses have identical dimensions.
