For the uninitiated, electro-optical sensors are detectors that convert light into electronic signals that can be understood by the corresponding measuring device. In a world that’s fueled by technology, the use of electro-optical sensors is diverse and extends to many fields. If you want to know more about optical applications, a simple example would be lamps that turn on easily when it’s dark. Most cameras and projectors do rely on optical sensors for functionalities and features. Sensors that are designed to detect things like presence of a thing are also common examples. Here are some more things to know about optical sensors.
The basics
In simple words, the purpose of an optical sensor is to convert light into electronic signals, for which it understands the quantity of light and translates the same into a format that’s understandable by the instrument. Mostly, optical sensors are used as a part of a product, which also have a measuring instrument. Depending on the function, optical sensors can measure the changes from different sources of light. In case of any change, the sensor works to alter the electronic output as required.
What are the types of optical sensors?
There are diverse optical sensors. The most common one is the photoconductive sensor that converts the light change into change of “resistance”. There are also solar cells, which convert light into what’s called the “output” or “voltage”. Photodiodes are also a kind of optical sensor that convert light into current, while phototransistors are also a type of optical sensors.
Applications and more
The use of optical sensors depends on the project, but in industrial setup and in case of consumer goods, the applications can be really different and unique. Smartphones are the most common products that contain optical sensors, which are used for adjusting features of the camera or to adjust the brightness of the screen. Smart watches also rely on sensors to take pulse rate. For conversion of electrical power, optical sensors are used in diverse industrial setups.
In conclusion
If you need to order optical sensors for a project or require help with prototyping, you can consider checking online for companies that specialize in manufacturing optical components. You can discuss your requirements, evaluate their capabilities and check the range of products they make. Don’t shy away from sharing your specific requirements, because the expertise of such companies depend on how they customize optical sensors for clients.
