- Nearly zero distortion*
The nearly zero optical distortion makes MC3M lenses perfectly suitable for high-precision positioning/inspection/measurement applications where a high depth of field is not required.
- Wide image circle for sensors up to 1.1”
- High resolution
Specifically designed to work in "macro" configuration at a fixed working distance.
- Simple and robust design for industrial environments
30 mm outer diameter for applications where only little room is available.
* Image distortion is the percent deviation of the real image acquired by the optics compared to an ideal, undistorted image. Our macro lenses feature "Nearly Zero Distortion", which means that although perfection is hardly reachable, the maximum distortion is designed to be as close to zero as possible.
MC3M series is a family of macro lenses designed to capture images of small objects when high resolution and nearly zero distortion are required.
Optimized for 1.1" sensors, MC3M macro lenses are specifically designed for macro imaging to get the best out of close-range inspections without compromising image distortion, resolution, depth of field, color fidelity, and measurement accuracy.
With magnifications ranging from 0.1x to 6x, these macro lenses are ideal for applications such as positioning/inspection/measurement of objects where a high depth of field is not required (bent metal parts, silicon wafers, quad flat no-lead (QFN) packages, etc.).
Their compact design and high quality/price ratio make them suitable for industrial environments with space restrictions.
- Working distance: distance between the front end of the mechanics and the object. Set this distance within ±3% of the nominal value for maximum resolution and minimum distortion.
- Working f-number (wf/N): the real f-number of a lens in operating conditions.
- Percent deviation of the real image compared to an ideal, undistorted image.
- At the borders of the field depth the image can be still used for measurement but, to get a very sharp image, only half of the nominal field depth should be considered. Pixel size used for calculation is 3.45 μm.
- Object side, calculated with the Rayleigh criterion with λ= 520 nm
- Measured from the front end of the mechanics to the camera flange.
