Lenses · Bi-telecentric
Bi-telecentric lenses
In a standard telecentric lens, constant magnification is guaranteed only on the object side. A bi-telecentric lens keeps rays parallel on the sensor side as well — removing the residual dependence of magnification on sensor position and markedly reducing distortion. Chosen where measurement is in microns: precision parts, inspection against a master, metrology benches.

How to choose
Look at distortion, telecentricity and the lens's own resolution — all three limit measurement accuracy, not just one. Depth of field on bi-telecentric lenses is quoted with an aperture condition (for example "± 18.9 mm @ F16"): at a different aperture the figure changes.
