Double Side Telecentric Lens-4M/29M

• Can apply for High Mega Pixel Camera like 4M,29M.
• Possible to adapt M58-Mount in case of 29M series but change the mount according to camera brand who have own flange back length.
• High resolution and high telecentricity regarding of all series.
• Iris diaphragm adapted for adjusting D.O.F.

Generally, standard telecentric lens are said to be object side telecentric. That means that the parallel beams originating from the object are reproduced on the sensor.

Thus telecentric lens is good for the accurate measurement tool that has no perspective error over the whole F.O.V. There is no changed the magnification in depth of field (D.O.F) even if up and down the W.D which is different with general lens.

Besides, general lens happen magnification changes when W.D moves up& down also perspective error and can see the barrier in case of height object. Finally, it is proper way to composite the system to accurate measurement in the machine field.
