Say my laser source is 1300 +/-10nm, with normal distribution 3 sigma, which operant to use to include it in the tolerance editor?
Thanks.
Solved
if my laser source has a wavelength range, how can I include that in my tolerance analysis (which operand to use)?

Hello
I’m not sure that’s what you’re asking, but here’s what I’d do.
- Setup a WAVE operand in the Multi-Configuration Editor and set it to 1.300 um
- In the Tolerance Data Editor add a STAT operand with Type 0 (normal distribution) and #Dev 3 (number of standard deviations), and a TMCO operand (tolerance multi-configuration operand) with the Row and Config# corresponding to the WAVE operand setup in 1., it should pick-up the nominal value of 1.300 um. Then simply add -0.010 um, and 0.010 um as the Min/Max respectively
If you run some Monte Carlo runs, this is what you’d get:
I hope this helps.
Take care,
