Comparison at 1400x (X5) is near the highest magnification of the NSH lens
■Features of Lens
When using extremely high magnification lenses (over 1000x), the difference in lens performance becomes apparent near maximum magnification.
・Blurred edges (aberration)
・Color fading (chromatic aberration)
Depending on the subject, edge blur (aberration) and color blur (chromatic aberration) can have a significant effect on appearance.
→If this level is reduced to the maximum, the lens price will increase significantly.
→On the other hand, depending on the subject, costs can be significantly reduced.
■Examples have little impact
When examining samples on silicon wafers, the edges may be slightly blurred but are still fully visible. (Photo below)
Lens used: NSH Lens (multi-purpose lens)
Lens used: USH Lens (high resolution lens)
■Examples have many influences
Edge blurring and chromatic aberrations are also present. Although the presence or absence of foreign objects can be determined, detailed observations cannot be made.
