Technicians utilize various types of equipment such as ultraviolet light, microscopes, spectrographs, x-ray machines and infrared photography. They also provide reports which include documentation of their findings and include the laboratory techniques which were utilized. Their findings often help to determine if a defendant is innocent or guilty of a crime.

Sometimes they may offer information and expert opinions to investigators. In addition, forensic science technicians often appear in court to provide expert witness testimony regarding laboratory findings. While in court, they typically identify and classify evidence that was collected at crime scenes.

Many in the profession specialize in different fields, including performing tests on weapons or substances such as fiber, hair or body fluids. Some specialize as crime scene technicians or laboratory technicians. Many technicians specialize in DNA analysis. Document technicians evaluate handwriting and the paper.
