Refractive power

Refractive power or optical power is the degree to which an optical system, such as a lens, converges or diverges light. Diverging lenses possess negative refractive power, while converging lenses possess positive refractive power.

Refractive power is an essential knowledge of the following occupations:

Photonics engineering technician: Photonics engineering technicians collaborate with engineers in the development of photonic systems or components, usually in the form of optical equipment, such as lasers, lenses, and fibre optic equipment. Photonics engineering technicians build, test, install and calibrate optical equipment. They read blueprint and other technical drawings to develop testing and calibrating procedures.
Optoelectronic engineer: Optoelectronic engineers design and develop optoelectronic systems and devices, such as UV sensors, photodiodes, and LEDs. Optoelectronic engineering combines optical engineering with electronic engineering in the design of these systems and devices. They conduct research, perform analysis, test the devices, and supervise the research.
Photonics engineer: Photonics engineers are concerned with the generation, transmission, transformation, and detection of light. They conduct research, design, assemble, test and deploy photonic components or systems in multiple application fields, from optical communications to medical instrumentation, material processing or sensing technology.
Optical engineer: Optical engineers design and develop different industrial applications with optics. They have knowledge of light, light transmission principles, and optics in order to design engineering specs of equipment such as microscopes, lenses, telescopes, and other optical devices.
Optomechanical engineer: Optomechanical engineers design and develop optomechanical systems, devices, and components, such as optical mirrors and optical mounts. Optomechanical engineering combines optical engineering with mechanical engineering in the design of these systems and devices. They conduct research, perform analysis, test the devices, and supervise the research.
Optomechanical engineering technician: Optomechanical engineering technicians collaborate with engineers in the development of optomechanical devices, such as optical tables, deformable mirrors, and optical mounts. Optomechanical engineering technicians build, install, test, and maintain optomechanical equipment prototypes. They determine materials and assembly requirements.
Optoelectronic engineering technician: Optoelectronic engineering technicians collaborate with engineers in the development of optoelectronic systems and components, such as photodiodes, optical sensors, lasers and LED’s. Optoelectronic engineering technicians build, test, install and calibrate optoelectronic equipment. They read blueprint and other technical drawings to develop testing and calibrating procedures.

Refractive power is optional for these occupations. This means knowing this knowledge may be an asset for career advancement if you are in one of these occupations.

Optical instrument assembler: Optical instrument assemblers read blueprints and assembly drawings to assemble lenses and optical instruments, such as microscopes, telescopes, projection equipment, and medical diagnostic equipment. They process, grind, polish, and coat glass materials, centre lenses according to the optical axis, and cement them to the optical frame. They may test the instruments after assembly.
Optical instrument repairer: Optical instrument repairers repair optical instruments, such as microscopes, telescopes, camera optics, and compasses. They test the instruments to ensure they function properly. In a military context they also read blueprints to be able to repair the instruments.
Photographic equipment assembler: Photographic equipment assemblers build photographic products such as cameras, film cameras, and projectors. They collect the different optical, electronic, and mechanical camera components, such as the battery, mirrors, image processor, and lenses, and piece together cameras according to specifications using hand tools or machinery.
