STS23 Series

With high telecentricity and low distortion, BASSON bi-telecentric lenses are mainly applied to precision measurement and high-precision visual positioning fields.
BASSON STS23 Series Standard Bi-telecentric Lenses are standard F-mount lenses, available for industrial cameras with maximum sensor size of 4/3” (diagonal of 23mm).

lOptical magnification: 0.920x-0.073x

lFOV: 25mm-315mm, satisfying different requirements on field of view

lWD: 50mm-545mm, satisfying different requirements on working distance

lDistortion: <0.05%, telecentricity: <0.05°

lBi-telecentric design, very deep DOF, high resolution

lMulti-layer coating, high transmittance

lIP 65 for use in harsh industrial environments

lOptions between high resolution and deep DOF are available, satisfying different

lCustomized aperture is available

lWorking distance can be adjusted within certain limits as per customers’ requirements
