Heavy Duty Lens, Ultra-Micro-Nikkor

Super High Resolution Lens

Technology

Enables a number of reduction printings of minute image patterns on a photo-resist under h-line monochromatic lighting (wavelength 407.7 nm, or g-line monochromatic lighting (wavelength 435.8 nm), or a combination of both.
Mounted on a photo-repeater, the principal role of this lens is to produce chrome masks (for IC and LSI manufacture) by means of the step-and-repeat method.
Its large 14 mm⌀ image area ideally suits it to the making of photomasks for large pattern unit LSI manufacturing processes.
With its standard 1/5 magnification, the lens guarantees resolving power of 650 lines/mm over a 14 mm⌀ image area (10 mm square), 800 lines/mm or more over a 10 mm⌀ image area.
