With high telecentricity and low distortion, OPTIGER bi-telecentric lenses are mainly applied to precision measurement and high-precision visual positioning fields.
          
 OPTIGER TTL23 Series Standard Bi-telecentric Lenses are standard F-mount lenses, available for industrial cameras with maximum sensor size of 4/3” (diagonal of 23mm).
