Details

Our 12X Zoom lenses offer the highest combination of zoom range and resolution in an optical system. Ideal for high magnification applications requiring the optimal balance between optical performance, large zoom range and price, the 12X offers incredible 12X (0.58-7X) magnification, increased resolution with 0.004-0.550 N.A., and unmatched edge flatness and clarity.

Assumptions:

1. Minimum resolvable feature size is half of the threshold line pair limit. Calculation = 1/(3000 x Lens NA)

2. Matching pixel size is that which will permit the minimum feature size to overlap two pixels. Calculation = 1/2(Feature Size x System Magnification)

3. If the matching pixel size is greater than the camera pixel size, the system is “lens limited.”, if less than the camera pixel size, the system is “camera limited.”
