Double Gauss (DG) Lens with low distortion and high performance
18mm to 75mm Focal Length
TECHSPEC® DG Series Fixed Focal Length Lenses utilize a Double Gauss design to provide high-performance, low distortion, compact size, and exceptional value, while exceeding the performance of typically available fixed focal length lenses. These lenses feature a mechanical design that allows the focusing movement to be motorized by the user, yields image resolution greater than 100 lp/mm, and have a standard C-Mount. For most applications, the camera-lens combination can be attached to workstations using the ¼-20 mount provided on the camera. TECHSPEC® DG Series Fixed Focal Length Lenses include focus ring, manual iris, and set screws to facilitate a low profile integration in machine vision applications. Typical applications for the DG Series lenses include machine vision, assembly-line integration, and measurement and image analysis.
Are you trying to measure the performance of your lens? Although this can be a difficult task, there are curves that can help. Read more at Edmund Optics.
Want to know more about the Modular Transfer Function? Learn about the components, understanding, importance, and characterization of MTF at Edmund Optics.
Do you have multiple projects that involve the use of a lens? Find out about different lenses that can be adapted for multiple purposes at Edmund Optics.
MTF curves allow you to compare the performance of multiple lenses at the same time. To find out how MTF curves are beneficial, read more at Edmund Optics.
Fixed magnification lenses typically function properly at a single working distance and are specified by their magnification. Learn more at Edmund Optics.

I’ve been using the thin lens approximation to calculate the minimum object distance and field of view of an imaging lens and camera I have, is there a simple formula for estimating these parameters?
Distortion is an individual aberration that misplaces information but can be calculated or mapped out of an image. Learn more about distortion at Edmund Optics.
When it comes to your lens, the f/# is one of the most important settings because it controls multiple parameters. Find out what the f/# controls at Edmund Optics.
While working with machine vision, there are different types of filters that can be used to alter the image. Find out about the different types at Edmund Optics.

In order to understand vignetting, it is important to understand sensor sizes, formats, and roll-off and relative illumination. Find out more at Edmund Optics.
Wavelengths can be both valuable or hazardous when trying to obtain information from an imaging system. Learn more about fixing wavelength issues at Edmund Optics.
Why Should I Use a Lens Designed Specifically for SWIR Wavelengths?
Short wave infrared (SWIR) imaging applications require specialized imaging optics, as lenses designed for visible use are not optimized for SWIR wavelengths
Imaging lens assemblies are vital components for a wide range of cutting edge applications including machine vision, biomedical instruments, factory automation, and robotics.
