In my opinion, Raman spectroscopy belongs to the category of scattering spectroscopy; from a light path perspective, no special collimation is required. Of course, such spectroscopes usually come equipped with a reference infrared or red laser for light path calibration. http://g.hiphotos.baidu.com/baike/c0%3Dbaike80%2C5%2C5%2C80%2C26/sign=ab85e74055da81cb5aeb8b9f330fbb73/d6ca7bcb0a46f21fb8e251e7f2246b600d33aeab.jpg The image above is the schematic diagram
