Although a common misconception, individual optical lenses do not always form an image when the object plane is placed a focal length away from the lens.
Large Diameter Gimbal Optical Mounts available from Edmund Optics are used to integrate large precision optical components, such as mirrors, into OEM and benchtop systems.
Important Concepts for Selecting Manual Translation Stages
Edmund Optics offers a variety of ball bearing, crossed roller bearing, dovetail, and rack and pinion translation stages for linear translation, rotary, and tip-tilt movement.
To select the best translation stage, it is important to understand key specifications such as resolution, load capacity, travel, accuracy, repeatability, and wobble.

Fresnel lenses are composed of a series of concentric grooves etched into one side of a sheet of plastic. Fresnel lenses are unlike typical spherical or aspherical optical lenses.
The TECHSPEC® MercuryTL™ Liquid Lens Telecentric Lenses combine the parallax error correction and high image quality of a telecentric lens with the flexibility of an integrated liquid lens.
Aspherized Achromatic Lenses, exclusive to Edmund Optics, are doublet lenses consisting of two cemented optical elements that are matched for their color-correction ability and small RMS spot size.
Telecentric illumination is quickly becoming the illumination of choice for precision metrology due to its ability to produce "hard" edges that can be easily analyzed.
