Introduction

POMEAS double-telecentric lens imaging principle is through the aperture in the middle of the lens placed so that out of the double-telecentric lens of the main light must pass through the center of the aperture, the other light is blocked by the diaphragm, unable to reach the imaging chip, and the imaging side Of the main light is necessarily parallel to the optical axis into the double telecentric lens.

The collimated light from the double telecentric lens ensures that the magnification of the image does not change even if the distance varies greatly within the depth of field.

As the double telecentric lens through a complex and special structural design, so that double-telecentric lens in a certain range can get a clear image, and its optical path has a "parallel to the optical axis" feature, eliminating the phenomenon of the edge of the dispersion circle.

In the use of POMEAS double telecentric lens, the object to solve the problem of depth of field, like the square to solve the problem of magnification changes. For telecentric lens selection and some other technical issues, solutions, please contact us: 400-646-6658,+86-0769-22660867.
