There are many different engineering careers you can go into, but optical engineering may be one of the most fascinating. Whether you choose to learn on your own or pursue an engineering degree, learning optical engineering can be one of the best decisions for your career.
What Is Optical Engineering?
If you have ever used a cell phone camera, you have used a product of optical engineering. This branch of engineering creates industry-standard optical instruments such as camera lenses, corrective eyewear, medical endoscopes, microscopes, and telescopes.
Optical engineers design the various optical components of devices. By using a combination of knowledge in the properties of light, physics, and chemistry, optical engineers can create real-world products that help us function in day-to-day life.
What Is Optical Engineering Used For?
Optical engineering is used for quite a few things, though its primary goal is to create quality optical devices. However, there is more to creating these products than meets the eye.
- Designing Optical Systems. Optical engineers use this field of engineering to design entire optical systems from the actual optical devices to the parts they interact with.
- Determining Required Specifications. Optical engineers also help determine what specifications are required for a variety of optical devices. They use these determinations to calibrate and fix issues with these devices.
- Designing and Developing Circuitry. The circuitry in optical devices is extremely important in how they function. While this could be designed by someone with an electrical engineering degree, most opt for optical engineering to ensure the job is done the exact way it needs to be for the optical device to work.
- Designing and Developing Inspection Instruments. Even though creating the actual optical devices is the fun part of the job, it is important to perform maintenance. Optical engineering is often used to design and develop instruments that inspect optical devices for any potential flaws.
Types of Optics
As an optical engineer, you will need to be well-versed in the world of optics. While there is a lot more to learn than these three primary types of optics, each is an important place to start.
Physical optics, as you can guess, focuses on the physical aspect of optics. It can be a bit difficult to simplify, but this type of optics revolves around the wave properties of light. By understanding the wave properties, you can better understand how light moves and bends.
Quantum optics is a bit more specific than physical optics. Rather than focusing solely on light waves, quantum optics is the branch that focuses on individual particles of light known as photons. This type of optics is essentially taking the theories and practices of quantum mechanics and applying them to photons and light.
Finally, we have geometrical optics. This type of optics focuses more on optical instruments and devices. When using geometrical optics, you will likely be using such instruments to detect, measure, and even manipulate light. This aids in the research and design of new optical devices.
Learning Optical Engineering
Learning optical engineering is no small task. But, if you want to take advantage of STEM education, this is a great way to do it. By enrolling in various STEM-related courses and eventually, optical engineering courses, you can teach yourself how to be an optical engineer.
Even if classes aren’t really your thing, this guide provides plenty of other resources. From books you can read to online resources and certificates you can earn, there are plenty of ways to learn all you need to know about optical engineering.
How Long Does It Take to Learn Optical Engineering?
To become an optical engineer, you will more than likely need to earn a college degree. This means, on average, it takes students at least four years to learn optical engineering. Those who have chosen to pursue a graduate degree would argue it takes upwards of six to eight years to truly master the subject.
However, if you are choosing to learn for fun or a personal project rather than a job, you can teach yourself quite a bit about the subject. Depending on what type of learner you are, you can teach yourself all you need to know in a few months or a few years. It really depends on your learning path.
How to Learn Optical Engineering: Step-by-Step
Though there are many different routes you can take to learn optical engineering, for those who are planning to become optical engineers, we suggest following these steps. This is also a good place to start if you are unsure of where to begin.
- Take Physics and Math Classes in High School. Even if you aren’t planning on earning an online math degree, enrolling in as many math and physics classes as possible in high school is a game-changer for future optical engineers. This gives you a better background in the area, providing you with a helpful head start.
- Apply to Good Optical Engineering Colleges. It can be difficult to determine which college is best for you to go to, so be sure to do your research. There are many good colleges for optical engineering, and it is important to find the best one for you by determining your budget, how prestigious you want the school to be, and where you want to study.
- Enroll in a BS in Optical Engineering Program. If your school offers it, we highly recommend enrolling in a Bachelor of Science in Optical Engineering program. These programs focus more heavily on science than others do, which benefits you as a future engineer as it gives you a more rounded education.
- Try to Enroll in a Co-Op Program. Not all schools offer co-op programs, but it is important to find out if yours does. These programs will help pair you with a company to intern or work at upon graduation, which saves you a lot of hassle when getting ready to join the work world.
- Consider Higher Education. Earning a BS in Optical Engineering is a huge feat, but in this competitive field, you should consider higher education. Having a master of science or even a PhD in the field would be a game-changer when it comes to future jobs.
