The maximum object dimensions shown in the table are 90% of the theoretical maximum dimensions, providing a safety factor for magnifi cation and alignment errors.

Image-side working f/# with lens aperture fully open. For combinations with teleconverters, the minimum image-side f-number is increased by the teleconverter 

  magnifi cation.

3

Lenses operated at smaller f/# may show reduced resolution, especially near the edge of the fi eld of view.

4

Depth of fi eld is calculated at f/11 for lenses with minimum operating f/# < f/16 (f/22 for all others) and for 30-µm allowable blur at the image (camera) plane.

Note: Distortion is less than 1.2% for all lenses. Contact Navitar for specifi c 
distortion characteristics for a particular lens.

Telecentric performance (<0.2° chief ray angle over 

the entire object fi eld) allows precise gauging of 

3-dimensional objects. 

• Large selection of magnifi cations covers most applications.

 

• Lockable aperture adjusts to select the required 

   

    depth of fi eld.
• Fine focus adjustment provides sharper images. 

Rugged single-piece design stands up to harsh 

• 

industrial environments. 
High-performance multi-layer coatings provide the

• 

 high-

est image clarity, especially for back-lit applications. 
Standard C-mount camera interface.

Features

The Invarigon-R™ family of gauging lenses provides telecentric imaging with a wide selection of magnifi cations. Invarigon-R™ 

gauging lenses are the most cost-eff ective choice for critical inspection and metrology imaging applications.

Invarigon-R

 Lens Specifi cations

Invarigon-R™

Teleconverter accessories can be used with select 

Invarigon-R

 lenses (59 LGU 031, 59 LGU 036, 

59 LGU 042, 59 LGU 050) to increase magnifi cation by 

a factor of 1.5x or 2.0x depending on the lens combina-

tion. Teleconverters cannot be used with certain types of 

3-CCD color cameras.
