A professional who designs optical systems with specific characteristics to fit within specified physical limits of precision optical instruments, such as still- and motion-picture cameras, lens systems, telescopes, and viewing and display devices. Responsibilities include:

• Determines specifications for operations and makes adjustments to calibrate and obtain specified operational performance.
• Determines proper operation of optical system and makes adjustments to perfect system.
• Designs mounts for components to hold them in proper planes in relation to each other and instrument in which they will be used.
• Designs inspection instruments to test optical systems for defects, such as aberrations and deviations.
• May work with electrical and mechanical engineering staff to develop overall design of optical system.
