All images shown were taken with a previous-generation Thorlabs DCC1240C color CMOS camera, MVL20A extension tube, MVL12X3Z zoom lens, and MVL12X20L magnifying lens attachment. The bottom pair of images are far-field (bottom-left) and close-up (bottom-right) views of a previous-generation Thorlabs camera.

Please note that our 6.5X zoom lenses must be used with an extension tube (sold below), and can optionally be used with a 6.5X system magnifying lens attachment (also sold below). The threaded end of the zoom lenses have M25 x 0.75 internal threads and 1.093"-32 external threads. Our 6.5X zoom lenses can easily be mounted using the C1512(/M) fixed or C1513(/M) kinematic V-clamp.

Spherical lenses have a consistent curvature across the entire lens surface. This shape is similar to a section of a sphere, hence the name.

Our 12X Zoom Lenses feature a variable magnification of 0.58 - 7X, which provides a 12X magnification adjustment (zoom) range. The MVL12X12Z provides 12 mm of fine focus travel for a large working distance range, while the MVL12X3Z provides 3 mm of fine focus travel, along with a coaxial illumination port, which is compatible with the fiber bundles included with our OSL2 and OSL2IR fiber light sources and our Ø5 mm liquid light guides.

AsphericLenses price

No. Aspheric lenses refers to the lens profile (cross sectional view), whereas high index refers to the lenses refractive index. Unlike single curve (spheric) lenses, aspheric lenses use varying curvatures in their profile. High index lenses denotes the lenses ability to bend light. With the same dioptric strength, high index lenses are thinner than standard index lenses.

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.

However, aspheric lenses are typically made with high index materials to enhance the benefits of thinner, flatter lenses. Lenses over a 1.67 refractive index are often aspheric.Spherical or aspherical denotes the profile of a lens. Spheric lenses use a single curve in their profile, whilst aspheric lenses use varying curves. These varying curves make your lenses thinner and generally flatter which makes them look nicer and prevents your eyes being magnified.Refractive index denotes a lenses' efficiency at bending light. The higher the refractive index, the better it bends light, the thinner a lens can be. In a strong prescription, 1.67 high index lenses will be thinner than 1.50 standard index lenses.Combining aspheric & high indexSay you need a +6.00 Sphere dioptre. High index 1.67 lenses will be thin, but  aspheric high index 1.67 lenses will be even thinner and look visually flatter. As a rule of thumb, the stronger your prescription, the higher refractive index you’ll need.

Slightly more costly than single aspheric lenses, this lens-type are even thinner and even lighter weight. Ideal if you’re heavily far-sighted and your prescription is stronger than +6.00.

If you have a strong prescription, it's best to invest in lenses which helps you see whilst keeping your eyes looking their normal size.

Aspherical spectacle lenses use varying curves across their surface to reduce bulk and make them flatter in their profile. Spherical lenses use a singular curve in their profile, making them simpler but bulkier, especially in the centre of the lens.

Thanks to their undulating curves, aspheric lenses reduce the aesthetic magnification of your eyes for a more natural sort of look.

Far-sighted (+) spectacle lenses are thickest at their centre; therefore, the flatter aspheric profile is much more aesthetically pleasing. Flatter and thinner aspheric lenses will fit a broader variety of frames, giving you more choice for your next pair of glasses.

Near-sighted (-) spectacle lenses are thickest at their edges. Aspheric lenses are less beneficial for minus prescriptions, but they'll still reduce edge-bulk and appear flatter than a spheric equivalent. Ideal for reducing the weight of your lenses overall.

Spherical lenses are best suited for those with mild prescriptions with a Sphere power of less than +/-4.00 or and Cyl power less than +/- 2.00. As they use a single curvature, they tend to be made from 'stock lenses' which makes them much cheaper and faster to produce and fit to your glasses.

Aspheric lens glassesprice

Yes. Progressive lenses (varifocals) feature varying curvatures and thicknesses within the lens, therefore they’re all considered as aspheric. As they provide a spectrum of focal power from the top the lens to the bottom, differing thicknesses are required.

If your prescription is fairly mild, say less than + / - 2.75 dioptres, aspheric lenses won’t be that much thinner. However, they’ll look flatter and sleeker.

If you’re still unsure, consult with an optician or eyewear professional. They can provide tailored advice based on your prescription, lifestyle, and budget.

Aspheric lenses are more expensive due to how they’re made. Becuase they use more complex curvatures, aspheric lenses are more difficult to produce than spheric ones, hence their increased cost. (Around 20%.)

Double aspheric lenses (bi-aspheric) are designed for strong minus (-) prescriptions which utilise aspheric curvatures on both their front and rear surfaces. These lenses have an enlarged field of view which provides greater vision and reduced distortion at the edges of your lenses.

Our 6.5X Zoom Lenses feature a variable magnification of 0.7 - 4.5X, which provides a 6.5X magnification adjustment (zoom) range.

These zoom lenses also offer direct compatibility with our LEDRW40 Ring Light, as shown for the MVL6X12Z in the image to the right.

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).

Magnification CalculationThe 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.
