Optical keyboards are a type of computer keyboard that uses light to detect key presses rather than physical switches.
They typically use infrared light and sensors to detect when a key is pressed, which allows for faster response times and increased durability compared to traditional mechanical keyboards.
In this blog, we will explore what optical keyboards are, how they work, and why they are the best option for typing and gaming.
What Are Optical Keyboards?
Optical keyboards are a relatively new type of keyboard that uses infrared light to detect when a key is pressed. Here are some benefits of optical keyboards:
Durability
Optical keyboards are generally more durable than traditional mechanical keyboards because they don’t have physical switches that can wear out over time.
Faster Response Time
Optical keyboards have a faster response time than traditional mechanical keyboards, which can make a difference in fast-paced gaming or typing.
Optical keyboards use a laser to control the actuation sequence, and the signal travels at the speed of light.
Quieter
Optical keyboards are also generally quieter to type on, as there is no sound made by the physical act of the key switch being depressed.
Resistance to Moisture
Optical keyboards are more resistant to moisture than mechanical keyboards, as they have no metal contacts that can corrode or rust. This makes them easier to clean and maintain.
Debounce Delay
Optical keyboards have no debounce delay, which is the time it takes for a switch to reset after being pressed. This can improve accuracy and prevent double-typing or missed keystrokes.
Customization
Optical keyboards have more customization options than mechanical keyboards, as they can adjust the actuation point and force of each key. This means that users can fine-tune their keyboard to their personal preferences and needs.
How Do Optical Keyboards Work?
Optical keyboards work by using infrared light and sensors to detect when a key is pressed. When a key is pressed, the infrared light is interrupted and the sensors detect the change in light, registering the keystroke.
This process is much faster than the mechanical process used in traditional keyboards, which requires a physical switch to be pressed down and released.
Different Types of Optical Switches
There are different types of optical switches that use different methods of interrupting the light beam. Some optical switches have a horizontal infrared light beam shooting across the inside of the switch shaft.
The stem of the switch blocks the light beam, but when you press a key, you push down the stem, allowing the light to make a connection across the shaft and actuate the command.
Other optical switches have a vertical infrared light beam shining from below the switch shaft.
The stem of the switch has a shutter that blocks the light beam, but when you press a key, you push down the stem, opening the shutter and allowing the light to reach the sensor above and actuate the command.
Optical switches can have different characteristics depending on their design and materials. Some optical switches are linear, meaning they have a smooth and consistent feel throughout their travel.
Others are tactile, meaning they have a bump that indicates when they actuate. Some are also clicky, meaning they produce an audible sound when they actuate.
Optical switches can also vary in their actuation distance (how far you need to press them to register), actuation force (how much pressure you need to apply), and a reset point (how far you need to release them to reset).
Why Are Optical Keyboards the Best Option for Typing and Gaming?
Optical keyboards are widely regarded to be the peak of performance in mechanical keyboards, especially for typing and gaming. Here are some reasons why optical keyboards are the best option for these activities:
Typing
Optical keyboards offer a smooth and responsive typing experience, as they have no hysteresis or debounce issues that can affect accuracy and speed.
Optical keyboards also have a lower actuation force than mechanical keyboards, which can reduce fatigue and improve comfort.
Gaming
Optical keyboards offer a competitive edge in gaming, as they have a faster response time and lower latency than mechanical keyboards.
Optical keyboards also have higher durability and reliability than mechanical keyboards, which can withstand more intense and frequent use.
Conclusion
Optical keyboards are a type of computer keyboard that uses light to detect key presses rather than physical switches.
They offer many advantages over traditional mechanical keyboards, such as faster response time, increased durability, quieter operation, resistance to moisture, debounce delay elimination and more customization options.
Optical keyboards are the best option for typing and gaming, as they provide a smooth and responsive experience that can improve accuracy, speed, comfort, and performance.
