Technician in Precision Optics (TPO)

Technician in Precision Optics (TPO)

Precision Optics technicians work in optical component fabrication technical areas in optical shops, optics manufacturers and in quality control departments (incoming and/or outgoing inspection) for organizations that incorporate precision optics into various systems. They must be able to examine the properties and uses of a variety of bulk materials; have experience in the use of equipment and procedures for shaping, polishing, and coating precision optics; and be able to use optical instruments, procedures and guidelines for verifying optical component dimensions and tolerances. They can also handle, store and ship precision optical components. Precision Optics Technicians have the minimum required hands-on competencies and experience with fabrication and test of fewer types of optics. Due to the high technical standards and safety issues involved, technicians will receive specialized training in both knowledge and hands-on skill items.

The knowledge component comprises of two separate exams totaling 98 questions. These
two exams must be taken within a two year period.
