Abstract: An apparatus includes: a handheld Raman analyzer that can include: a common platform; a laser assembly mounted on a laser platform, the laser platform supported on the common platform by a first material and a second thermally conductive material wherein the first material is softer than the second material; an optical probe head assembly disposed on the common platform, the optical probe head assembly spaced apart from the laser assembly; a spectrometer assembly disposed on the common platform, the spectrometer assembly spaced apart from the optical probe head assembly; and an analysis apparatus configured to identify a specimen based on a Raman signature received from the spectrometer. The laser assembly can be optically coupled to the optical probe head assembly by at least a first free-space coupling region and the optical probe head assembly optically coupled to the spectrometer assembly by at least a second free-space coupling region.
