TECHSPEC® C Series Fixed Focal Length Lenses
are designed for use in machine vision applications
with the working distance and resolution requirements
of factory automation and inspection in mind.
TECHSPEC® C Series Fixed Focal Length Lenses
feature large maximum apertures, allowing these
high performance lenses to be used in even the
most restrictive lighting conditions. Each lens has a
broadband anti-reflection coating, locking iris and
focus adjustment with recessed set screws, and a
ruggedized, robust housing for space-restrictive applications.
C Series lenses are manufactured to high
tolerances, which result in high levels of imaging performance
with low lens-to-lens variation. Through
combining optical performance, industrial features,
and compact package sizes, our TECHSPEC® C Series
Fixed Focal Length Lenses are ideal for use in
factory automation and inspection.
