Imaging lens performance can be enhanced with the use of liquid lenses. Learn more at Edmund Optics.

Have an application in a demanding environment? Learn about the different types of ruggedization: industrial, ingress protection, and stability at Edmund Optics.

Fixed focal length, zoom, and macro lenses are all variable magnification lenses. Learn more at Edmund Optics.

Telecentric Lenses can grow quite large and heavy with small magnifications, as such magnifications require large front optics. Learn more at Edmund Optics.

To decide what imaging lens is right for a system, it is important to know the parameters of the imaging system used. Learn more at Edmund Optics.

The modulation transfer function of a lens varies depending on working distance, sensor size, f/#, and wavelength. Learn more 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.
