Plus evaluation of the spot size is given in the ,ost conservative way while actual size have to sclaed down by wavelength/effective index of pixel stack material - it is ~1.5X smaller<br />VictorAnonymoushttps://www.blogger.com/profile/13492088158330912997noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-70471408117186536242021-11-04T21:32:32.598+02:002021-11-04T21:32:32.598+02:00The diameter of a diffraction limited spot can be ...The diameter of a diffraction limited spot can be calculated as FWHM=Wavelength/2/NA. For a lens with NA=0.26 this means about 1.1µm at 550nm and 1.3µm at 650nm. And that's just for the central peak of a periodic sinc function. In my experience it is everything but simple and inexpensive to really illuminate only one single pixel below 2µm size, especially when there is a cover glass in the way. <br /><br />JHAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-74988391614784942372021-11-03T07:09:23.851+02:002021-11-03T07:09:23.851+02:00Yes.
