FAQ
What Is The Resolution(Μm) Of The Lens?
Resolution is a measured by how closely 2 points can be before they cannot be distinguished. For example, 1μm resolution means that 2 points that are 1μm away from each other can be distinguished. Resolution values in this catalog are theoretical resolutions for the lenses. The following is a formula to calculate theoretical resolution based on a lens's ray diffraction with no aberration.
Resolution=0.61×λ/NA λ : Wavelength 0.61: Fixed Number
Distortion
(%)
Distortion is the aberration of a lens where a straight object outside of the optical axis appears curved. Distortion of a straight line towards the center is called pincushion distortion, while distortion expanding outwards is called barrel distortion
WD
(Working Distance)
Distance from the front end of a lens system to the object under inspection.
F Number
The value indicates lens brightness. It is calculated by dividing the focal distance of the lens by its effective diameter (entrance pupil diameter D mm) looking from its object side. It can also be calculated by NA and the lens' optical magnifi cation ( ). The smaller the number the brighter the lens is.
F No=f/D
Field Of View
Field of view is the size of an object that can be shot when the lens is attached to a camera.
The size of fi eld of view is (sensor size) ÷ (optical magnification ).
(Calculation Example) Optical Magnification =0.2x, camera Size 1/2" (4.8mm Long, 6.4mm Wide) :
Size of Field of View Length =4.8/0.2=24 (mm)
Width =6.4/0.2=32 (mm)
