Imaging Lenses
Where to Start?
IMAGING SYSTEM BASICS
There are a few basic parameters that should be understood about every imaging system. Knowing
these parameters will help in selecting the ideal lens and camera combination.
FUNDAMENTAL PARAMETERS:
Field of View (FOV): The viewable
area of the object under inspection. This
is the portion of the object that fills the
camera’s sensor.
Working Distance (WD): The distance
from the front of the lens to the object
under inspection.
Resolution: The minimum feature size
of the object that can be distinguished by
the imaging system.
Depth of Field (DOF): The maximum
object depth that can be maintained entirely
in acceptable focus. DOF is also the
amount of object movement (in and out
of best focus) allowable while maintaining
focus.

• Waterproof (Cw) Versions of TECHSPEC® C Series Lenses
• Meets IEC Ingress Protection Rating of IPX7 & IPX9K
• Hydrophobic Coated Window Protects Front Lens Element
• Designed to Eliminate the Need for a Protective Lens Cover
TECHSPEC® Cw Series Imaging Lenses are waterproof versions of our TECHSPEC® C Series Fixed Focal
Length Lenses. Designed to meet IEC Ingress Protection Code IPX7 and IPX9K, these lenses withstand exposure
to water up to 1 meter depth for 30 seconds and operate in close-range high presure, high temperature
water spray downs. These lenses include a hydrophobic coated window to prevent water droplets from settling
on the lens' surface. To prevent moisture from entering the housing, the lenses are sealed with multiple o-rings.
TECHSPEC Cw Series Imaging Lenses are designed for up to 5 MegaPixel, ⅔" sensors and are ideal for applications
including food, pharma, automotive, and security.
