Why is it commonly said that telephoto lenses are better suited for measurement applications?
Standard industrial lenses are designed for general-purpose imaging and suffer from unavoidable perspective distortion and magnification errors; they are suitable only for routine visual inspection......
Why is it commonly said that ZOOM LENSes are better suited for semiconductor inspection solutions?
Semiconductor inspection requires both broad-area initial inspection and micron-level microscopic re-inspection; fixed-focus lenses can only provide a fixed field of view, and frequent lens changes......
How do large-aperture FA lenses improve detection stability?
Thanks to their exceptional light-gathering capabilities and versatility, large-aperture FA lenses have become a key tool for solving visual inspection challenges in complex lighting conditions....
Still struggling to see fine details? High-resolution FA lenses
In response to the high-end manufacturing industry’s relentless pursuit of high resolution and low distortion, the all-new 20-megapixel FA industrial lens series has been introduced....
What is a ZOOM LENS?
A ZOOM LENS is a specialized type of lens that allows for continuous adjustment of the optical magnification. Unlike fixed-focus lenses, it enables users to flexibly switch between field of view an......
How High-Resolution Telecentric Lenses Handle Multi-Scene Inspection
Parallel measurement of screw threads, precision stamped metal parts, and electronic connector arrays requires both the elimination of perspective errors and the ability to clearly visualize minute......
How do telephoto lenses eliminate parallax at the optical source?
Telecentric lens solutions do not affect dimensional measurements due to changes in height and are commonly used in vision measurement systems....
