> 3 dayI get a clear 228lp/mm or 2.19 line width (not line pair width) verified resolution [see image - chromium on glass test target, group 7 line 2 is 228 lp/mm) from this little guy using white light table (no condenser) - which is quite good given that the Rayleigh criterion for blue light (450nm) suggests resolution of 2.74 for NA of 0.1 as this objective is. Granted, Rayleigh criterion is not the strictest but for $24 this is pretty amazing.
