According to the web page, the image circle on this thing is tiny - 2.9mm
That would require a very small very dense sensor, smaller even than that of a camera-phone.
I wonder what they used these things for ? |

I would assume that was for chipmaking. The small image circle and the f0.50 (very high NA) speaks for that. _________________ Klaus - Admin

Not for chip-making in 1948.
I spoke about a sensor looking at how one would use it now, but back then it would have been a similarly tiny bit of film.
Maybe it was for a genuinely spy-ish application like working with micro-dots. |

maybe it was used in an 'attempt' to creating chips _________________ Mr Scott please restrain your leaps of illogic. I have said nothing. I was merely speculating. |
