A better 1st mirror alignment and a 2nd 150mW laser line test:

The plot above has a FWHM value of 1.005nm resolution.
Fixed the 1st mirror position, I have much better resolution now :)

Another test scan today using my Aries 150mW green laser and a 0.1mm slit width @ 3ms integration time:
A little bit of clipping can be seen even though I had the variable polarizing lens at 75% still got a resolution factor of 2nm :)

7 Dark Count scans I did to determine which integration time is the most ideal and it appears to be 50ms, 15ms and 10ms:
