Edmund Optics (EO) will exhibit its Techspec compact telecentric lenses at the Vision Show in Stuttgart, Germany.
The lenses, suitable for integration into gauging systems, feature an ultra-compact design and provide excellent telecentricity and low distortion, the company said.
Telecentric lenses provide constant magnification within the entire depth of field with no perspective error.
The lenses are optically correct for parallax so that objects remain the same perceived size, independent of their location in space.
Their fixed iris and focus make them suitable for manufacturing, assembly lines and robotics applications as they will remain stationary over time.
Typical applications for telecentric lenses include metrology, CCD-based measurement and microlithography.
Techspec lenses are available with a 65mm primary working distance with primary magnifications of 1x, 2x, 3x and 4x.
Lenses with a working distance of 110 mm are offered with primary magnifications of 0.5x, 0.75x, 1x and 2x.
All sizes provide a large maximum sensor format of 2/3in, distortion of less than 0.2 per cent and telecentricity of less than 0.2.
All accommodate a C-mount camera mount.
Techspec Compact Telecentric Lenses are suitable for a range of tasks, from single-unit inspection stations to high-volume inspection applications in factory environments.
