In the world of optical lenses, macro lenses and FA lenses each have their unique characteristics and application scenarios. As an optical lens manufacturer, POMEAS will deeply analyse the differences between these two lenses from multiple angles to help you better understand them.

Design Principles and Functions:

Macro Lens: Mainly used for photographing very close objects and achieving high magnification. The design principle is to adjust the position of the lens group, the lens as a whole to the imaging plane, so as to achieve the magnification of the image. This design allows macro lenses to have extremely high magnification and very short closest focus distances, often achieving magnifications of 1:1 or higher and closest focus distances of a few centimetres or less.

FA Lens: Factory Automation Lens. Mainly used in industrial production vision inspection, intelligent identification and other fields, FA lenses usually have a greater depth of field and a wider field of view to adapt to the industrial production line of different distances, different sizes of objects detection needs. And FA lenses also have strong aberration correction ability and high resolution to ensure the stability and accuracy of image quality.

Performance Parameter Comparison:

Magnification and Nearest Focus Distance: Macro lenses usually have a higher magnification than FA lenses and a shorter nearest focus distance. This gives macro lenses a greater advantage when shooting close objects, while FA lenses are better suited for shooting objects that are farther away and have a wider field of view.

Resolution and image quality: Although FA lenses have reached a certain level of resolution, macro lenses still have higher requirements in terms of image quality. Macro lenses usually use higher level optical design and materials to ensure that the image quality is still clear at higher magnification.

Aberration Correction: Since macro lenses are mainly used for shooting close objects, their aberration correction capability is relatively weak. FA lenses, on the other hand, require strong aberration correction to ensure that accurate image information can be obtained at different shooting distances and viewing angles.

Application Scenario Comparison:

Macro Lens: Mainly used for photographing subtle objects such as insects and flowers, as well as high-precision objects such as jewellery and cultural relics.

FA Lens: Used in industrial production, quality inspection, intelligent identification and other fields, such as parts inspection, barcode identification, face recognition and so on.

When choosing a lens, you need to choose according to the specific application scene and needs. If you need to shoot fine objects or high-precision items at close range, you can choose a macro lens; if you need to be applied in industrial production, quality inspection and other fields, you can choose a FA lens.

As a professional manufacturer of optical lenses, POMEAS has been continuously learning and exploring new technologies and materials to promote the continuous development of optical lens technology.
