Thorlabs' Zoom Lenses are ideal for high-magnification machine vision and imaging applications, providing an optimal balance between optical performance and a large zoom range. These zoom lenses must be used with an extension tube (sold below), and can optionally be used with the appropriate 6.5X or 12X system magnifying lens attachment (also sold below).

Our modular system consists of a 0.7 - 4.5X zoom lens (6.5X zoom range) or 0.58 - 7X zoom lens (12X zoom range), along with 0.50X, 0.67X, 1X, 1.33X, and 2X extension tubes and optional 0.25X, 0.5X, 0.75X, 1.5X, and 2.0X magnifying lens adapters. Together, these components allow our 6.5X systems to provide a net magnification of 0.09 - 18 with a 6.5X magnification adjustment range, and they allow our 12X systems to provide a net magnification of 0.07 - 28 with a 12X magnification adjustment range. The magnification adjuster (zoom) is a recessed rotating collar on the barrel of the lens, which allows the magnification to be adjusted even when the lens is mounted in a V-clamp. Please note that only one magnifying lens attachment may be used at a time.

Magnification Calculation
The net magnification, M, of the system (M = image size / object size) is equal to the magnification of the magnifying lens attachment, multiplied by the magnification of the zoom lens (at its current setting), multiplied by the magnification of the extension tube. For example, the 12X zoom lens can be set to a magnification between 0.58X and 7X (corresponding to a 12X zoom range). If it is used at its maximum magnification setting of 7X, along with a 2X lens attachment and a 2X extension tube, the maximum system magnification of 2 x 7 x 2 = 28 is realized. See the Specs tab for the maximum and minimum magnifications of each lens combination.

The MVLCMC C-mount adapter is available for attaching these lenses to cameras that use a standard C-mount. The MVL20FA 2X extension tube with an F-Mount bayonet mount is also available. Please note that the zoom lenses must be used with an extension tube (or the image will not be able to be focused), while the magnifying lens adapters are optional. Additionally, when used with our SM1A9 or SM1A10 adapters, the zoom lenses sold on this page can be integrated with Thorlabs' SM1-threaded optomechanics.

Thorlabs also offers Standard C-Mount Machine Vision Lenses.

  • Matching pixel size is that which will permit the minimum feature size to overlap two pixels. [Pixel Size = 1/2(Feature Size x System Magnification)]. If the matching pixel size is greater than the camera pixel size, the system is "lens limited". If the matching pixel size is less than the camera pixel size, the system is "camera limited".
  • Refers to the zoom setting of the lens.

  • The above fields of view are measured diagonally across the sensor. (Horizontal = Diagonal x 0.8 and Vertical = Diagonal x 0.6).
  • Refers to the magnification setting of the zoom lens.
  • Vignetting occurs at zoom settings of less than 0.9X.
