This post brought to you by a laser professional who cringes at some of the home made LPMs he has seen.
Granted many hobbyist Peltier based systems are well made, but I've seen , evaluated, (and re-calibrated) some semi-production models that also really make me cringe.
Detector area not so great, 110$ is not that inexpensive, but a damn good coating , good minimum sensitivity, and good linearity.
