The FELM-532-20T from Frankfurt Laser Company is a Mini Green DPSS Laser that provides an output power of 20 mW at 532nm. The wavelength is 532nm with high color purity and strong mono-chromaticity due to an integrated infrared filter on the output window. It has an integrated photodiode to measure the output power, which allows using it with APC circuit and achieving high power stability. The beam coming from the laser has a size of 2 x 2 mm with a divergence of nearly 10° in both directions. It is available in a TO56 can (Ø5.6 x 6.5mm) package.
