Open loop vs closed loop water cooling

When it comes to PC games, the topic of peripherals is less than that of gaming mice. Finding a mouse that strikes a perfect balance between precision, design, ergonomics, and sensitivity is always a difficult task, but if we include sensor type, optical or laser in this list, which is the best? Well, the truth is that most modern gaming mice are equipped with excellent optical sensors. Laser sensors took the second place a few years ago, and optical sensors are the strongest choice in all aspects.

Ten years ago, the sensor you chose depended largely on your preferences, but it could also be due to the gaming surface you were using. In some respects, a laser mouse can handle a wider range of surface types and performance is often similar, which can affect many people. 4,444 mice are getting better year after year, and internal sensors have been at the forefront of this change. Optical sensor is now the best choice for mouse light source!

Before optical and laser mice

Before precision, comfort, and all those nice factors associated with your brilliant gaming mouse, we have a mechanical mouse. That? Yes, this is a mouse with a rubber ball inside. You must clean all kinds of dirt and grime regularly before you can load the contents of the floppy disk. The working principle of the

mechanical mouse is to detect whether there is light. There are two small wheels inside the mechanical mouse, one for vertical movement and the other for horizontal movement. When you move the mechanical mouse, the rubber ball will turn one of the corresponding wheels inside, and if they move at the same time, it will move diagonally.

When one of these inner wheels moves, it temporarily blocks the beam. The mouse will record this lack of light and which wheel it came from, which will make the cursor follow that direction. Chapter

What is the difference between an optical mouse and a laser mouse?

In this section, let's start by refuting the title a bit. That's right, in theory, all mice are optical. Modern mice are essentially cameras, constantly photographing the surface below. These low-resolution cameras that take pictures are called CMOS image sensors. The images they take are converted into data, which is used to track the current location of peripheral devices. CMOS combines two lenses and a light source, and can track the movement of the X-axis and Y-axis thousands of times per second.

We say that all mice are optical, only because they can take pictures. Despite this definition, optical mice rely on red or infrared LEDs to shine light onto the surface you use. LEDs are usually installed behind angled lenses to focus the illumination in the beam. The beam bounces off the mouse pad or table, passes through the magnifying glass, and then reaches the CMOS sensor.

The sensor then converts the beam into a stream, which in turn converts to 0 and 1, thereby capturing more than 10,000 digital images per second. It generates the precise mouse position and sends the final data to the PC every 1 to 8 milliseconds to obtain the cursor position.

Surface compatibility

As mentioned above, an optical or laser mouse must be illuminated to follow the movement. Traditionally, since LED lights cannot penetrate the surface, an optical mouse is always better on a hard or shiny mat. Of course, the latest developments in optical sensors mean that they can now work on almost any surface, but this has been the case in the past.

At the time, the laser did an excellent job of penetrating the surface, and due to its more powerful beam, it could even be used on glass surfaces. While this sounds positive (and many people thought about it at the time), laser sensors are more likely to acquire too much information when scanning, causing them to be inaccurate or drift at high speed. Chapter

Laser Mouse, Which Is Better?

So both methods use a light source to track the surface, but do you choose optical or laser? The short answer here is almost always optical, especially for gaming, but let's dig a little deeper. The

laser can penetrate deep into the surface texture without damaging anything and capture the smallest details. In theory this will make it more accurate, but unfortunately, it cannot be used for tracking. This seems to be the main problem with laser mice, as they are too precise and collect unwanted information, resulting in a poor user experience. As we all know, jitter is almost completely eliminated in the optical gaming mice we see today.

You can argue which one is better depends on preference or the purpose for which you intend to use the mouse, but the bottom line is: optical mice dominate. In the past, the main reason for the defense of optical mice may simply be that most of the people who sit at their desks have mouse pads. Over time, LED-based optical mice have continued to grow and develop, and while they provide some of the best consistent tracking, this type of lighting can track on a wider surface than ever before. The

still has the position of the laser sensor, but it is mainly for those who will not disturb the mouse pad. We can assume that most gamers will have a mouse pad to play consistent games and ensure that the desktop will not be damaged. People who work from home or on the go may not need the precise tracking capabilities of an optical mouse, and they may want something that can work on any surface they encounter that day. In this sense, the laser mouse is perfect because of its penetrating beam.


The foggy days of the past are over, and when it comes to gaming, since all major brands are equipped with powerful and reliable sensors, you do have many choices. Chapter

Laser Mouse-There is no doubt that the optical mouse wins in the general use of games and mouse pads, but it can be said that the laser mouse also has a certain audience.

Therefore, unless you plan to work with a glass table, buy a more accurate, affordable, and reliable optical mouse.
