A telecentric lens is specially intended
for machine vision measurement applications to boost the performance. They help
in taking accurate measurements of an object's dimension will be free of where
it is located.
These Telecentric Lenses are accessible with various
features for an assortment of machine vision or inspection applications that
you can get from a reliable telecentric lens supplier online.
You can choose according to your requirements.
We have various conventional lenses that are incapable of
increase the magnification of an object which is called perspective error or
parallax error. As a result, it decreases the accuracy as the observed
measurement of the vision framework will change if the item is moved because of
the magnification change.
To sort out this parallax error, telecentric
lens is widely used and you can have a constant, non-angular field of
view regardless of what is the distance of an object from the lenses. You can
have the same size as it.
When it comes to the benefits of Telecentric Lenses, its
magnification does not change in regard to profundity. However, with the Fixed
Focal LengthLens, you cannot confirm which object is in front of the other.
Many people think that Telecentric Lenses integrally have a
bigger profundity of field than conventional lenses which is not true. These
focal points can have a bigger usable depth of field because of the symmetrical
blurring on either side of the best focus. But when the item moved out from the
focus, the non-telecentric lens can not get the right result due to parallax
and the magnification alteration that is related to its angular field of view.
At the same time with the Telecentric Lenses, the blur symmetrically and
accurate measurement can still be made when the item is outside the best focus.
It increases the efficiency of the machine vision system.
Telecentric Lenses are also used in metrology applications
is that Telecentric Lenses commonly have lower alteration values than Fixed
Focal Length Lenses.
If you want to buy these lenses, you need to find out the
best telecentric lens manufacturer online. They can give you
the best deal.
