Finite Imaging

Our low-profile compact lenses are designed to provide high image quality with low distortion when the object distance is greater than about 10 times the focal length, or for on-axis imaging. They are applicable for finite object imaging applications such as face/object recognition, barcode readers, document imaging, machine vision, and biometric security. 

We provide two online wizards to assist you to choose the right lens: 

  • Imaging optics solver: Solves for the effective focal length (EFL) based on object and image size constraints. A good starting point for finite conjugate applications such as barcode scanning, etc.
  • Field of view or EFL calculator: Calculates FOV (in degree) of a lens on a given imager if the EFL is known, and vice vesa. This wizard factors into the geometric distortion of the lens.  Therefore, it is applicable to all lenses from telephoto to fisheye types.

Robotics Vision

Many of Sunex standard wide-angle and fisheye lenses are suitable for robotics vision applications.  For 3D applications we offer Boresight Stabilization – a proprietary technology eliminating lateral shift (Boresight) of the lens elements due to shock or vibration. This is especially critical in 3D imaging, where a shift of just a few pixels is often unacceptable.  


Sunex wide-angle and fisheye lenses are becoming increasingly popular in a variety of inspection application, such as boroscopes or pipe inspection.  Several factors make Sunex lenses ideal for this type of application. The low profile and small physical sizes of our lenses, combined with small sensor formats for which the lenses were designed, allow for very compact camera packaging. Moreover, our ability to customize provides you with a variety options to meet your unique requirements. 

Customization Capabilities Include:

  • IP rated sealing

  • IR coatings with IR band-pass for Day/Night imaging (IRC40)

  • Hydro-phobic/phillic coatings

  • Relative aperture (F/#) modifications (calculate depth of field)

  • Mechanical barrel redesign  

  • Boresight Stabilization
