Telecentric Lens On Image Side
Image_side telecentric lens make main ray parallel to optical axis get by put aperture on object-side focal plane, thus although the installation site of CCD chip is changed, projection imagine big or small on CCD chip is invariant.
Application:
Machine vision, measurement and precision measurement, etc.
Specification:
Telecentric degrees : < 0.1 °
Abnormal change : < 0.3 %
Magnification : 0.16X ~ 4X
Coating : AR @ 425nm ~ 675nm
