1. An apparatus comprising:
a laser light source;
at least one adjustable mirror configured to enable laser light from the laser light source to be incident on the at least one adjustable mirror and to enable at least some of the laser light reflected by the at least one adjustable mirror to be used for scanning of a sample, wherein the at least one adjustable mirror is configured to reflect two different wavelengths of laser light from the laser light source including a first wavelength, comprising infrared light, and a second wavelength, comprising visible light;
at least one image sensor; and
one or more optical components configured to guide a first portion of the laser light reflected by the at least one adjustable mirror towards the at least one image sensor so that one or more images obtained by the at least one image sensor provide an indication of a position of the at least one adjustable mirror, wherein the at least one image sensor is configured to provide an image of the sample and the indication of the position of the at least one adjustable mirror simultaneously, and to direct a second portion of the laser light reflected by the at least one adjustable mirror towards the sample.
