Macro lenses were specifically designed to record images of tiny objects, when excellent resolution and none distortion are required. Utilizing a macro lens for visual inspections can prove advantageous in some situations when the close-up inspection of tiny objects, or even finer details are needed. Vision inspection equipment is commonly utilized in the industrial setting to streamline quality control procedures to detect and identify defects, calculate the dimensions of objects, and carry out different visually-inspected tasks.
A macro lens has been made specifically to target things at close ranges and allows large-resolution photos of tiny things or even details that may not be obvious to the naked eye, or ordinary lens of a camera. The small fields of view are usually observed through the use of long focal length lenses that come with a spacer that is used to alter the focal length.
This method can cause numerous issues, including high image distortion, low resolution (especially in the corners) and a lack of depth of field as well as effects due to chromatics, which makes the method unsuitable to provide high quality imaging, nor is it suitable for accurate measurements.
Each of these issues can be addressed with Macro lenses. The very little optical distortion makes them perfect for precise dimension measurements.
Key Advantages:
Zero distortion: Zero distortion is suitable in any application of measurement in which telecentricity is not needed.
High-resolution: MC Series has been specifically developed to work in "macro" configuration.
The compactness of the lens: Macro Lens outer diameter (15 millimeters) can be used in situations in which only a small space for optical components is provided.
High Magnification: Micro lenses are made to give high-magnification capabilities that allow close-up inspection of tiny objects as well as tiny specifics.
Improved Depth of Field: Lenses with macro lenses usually feature a narrow depth of field. This allows the subject to be isolated from the background. This can be beneficial in vision inspection because it minimizes distractions and makes sure that the attention only focuses on the key zones of interest.
Automated and efficient: Once included in automated vision inspection systems macro lenses are able to quickly and effectively examine a wide variety of objects, decreasing the need for human intervention as well as increasing the efficiency of inspection.
