Thorlabs offers alignment lasers to assist in aligning optical beam paths. These alignment lasers range in wavelength from the visible to the NIR. The compact laser modules are equipped with a USB connector, phono jack, or bare wire leads. The phono-jack-equipped laser modules are available with collimated or adjustable-focus output. The HeNe lasers are offered with output powers ranging from 0.8 mW to 22.5 mW at 632.8 nm, with either linearly or randomly polarized output beams. In addition, we offer a handheld laser source with a rechargeable battery.
