Lesson 17 – Quantitative Descriptions of a Lens
In theory, the entire lens would be up to the qualifications set by the customer. After all, if a customer ordered a 150mm lens, the whole 150mm lens should be
Optical Tolerances
Manufacturing optical tolerances are important factors that impact both performance and cost of an optical component or system. Optical components commonly require tighter optical tolerances than mechanical components. Cost Drivers
Lesson 16 – Optical Systems II: Spherical Lenses
We briefly discussed spherical and aspherical lenses in “Intro to Optical Components”. Spherical lenses can further be broken down into different categories. Plano convex lenses are flat on one side
Clear Aperture
During the manufacturing process, a lower quality surface near the edge of an optical component is created. The diameter of the area inside of the optical component that must meet
Lesson 15 – Optical Systems I
Lenses come in all different forms, not just through the process of manufacturing. In fact, our own eyes are an optical system. Four main “components” to our eye are: 1)
Lesson 14 – How do Atoms Emit Light?
Light sources such as the sun give off light, but why? The equation E = hf relates the wavelength of light to energy where E is energy, h is Planck’s

Camera Lens Field of View (FOV)
Field of view (FOV) is defined as the maximum area that a device can capture. The larger the field of view, the more data can be captured at one time,
Lesson 13 – Diffraction Grating and Wave Plates
With the knowledge of interference and polarization, it is time to talk about the practical applications of both! Diffraction gratings are used to change the path of light and there
Lesson 12 – Polarization Revisited
Now that we have explored light waves, we can dive more in depth into polarization. In how to describe light, we mentioned that sunlight is a form of unpolarized light
