Whether you use it for work or play, our hands are a gripping mouse almost every day. What is the difference between an optical mouse and laser mouse?

By choosing a mouse for yourself

They are on the shelves of stores in a huge assortment and are mostly intended for right-handers, while a few have an ergonomic design that is suitable for left-handers. Of all the features and shape factors, you will find two basic versions of the computer mouse: with an optical sensor or based on a laser. Which is better? Let’s figure it out.
Guess what? All modern computer mice are optical
modern computer mice are the same cameras that instead of capturing faces take pictures of the surface from below (table, stand, etc.). the images are converted to data to track the position of the periphery on the surface. Lastly, this low resolution camera in your hand is only designed to track X and Y coordinates thousands of times per second. Basically, all computer mice consist of a small low resolution (CMOS sensor), two lenses, and a light source. All mice optical, from a technical point of view, because they collect data in an optical way. but they sold as optical models rely on an infrared or a red led that projects light on the surface. this led is usually seen at an angle, focusing the light on the beam. the beam bounces off the surface, through a lens that magnifies reflected light, and transmits to a cmos sensor. The CMOS sensor collects light and converts light as particles into electric current. This analog data is then converted to 1 and 0, resulting in more than 10,000 digital photos being taken every second. These images are in relation to creating the exact location of the mouse, and then the final data sent to the PC to place the cursor every one-eighth of a millisecond. On older LED mice, you may have noticed that the LED pointed straight down and shone like a red width on the surface that the sensor saw. Now LED lights are projected at an angle and are usually invisible (infrared). This helps the computer mouse to track movements on most surfaces.

Laser pc mice are more sensitive

Meanwhile, Logitech, was the first company to introduce the term using a laser for a mouse back in 2004. In particular, it is called a vertical cavity laser diode, or VCSEL, which is used in laser pointers, optical drives, barcode readers, and other devices. This infrared laser only replaces the infrared / red LED light on optical models. But do not despair: it will not clutter up the eyes, because it emits light only in the infrared spectrum, which the human eye does not perceive. This main advantage allows the laser mouse to use a width of greater intensity, which provides better visualization and increased sensitivity. At one time, laser models were considered far superior optical versions. Over time, however, optical mice have improved, and now they work in a wide variety of situations, with a very high degree of accuracy. The advantage of the laser model is due to the higher sensitivity than the mouse on the LEDs. However, if you are not an avid player, this is not such an important feature.
what is the difference between optical and laser mice when using?
so, what is the difference between using an optical and laser mouse, other than the difference in lighting? to begin with, it should be mentioned that both methods use surface irregularities to track the position of the periphery. however, the laser can penetrate deeper into the surface structure. this provides more information to the cmos sensor and processor inside the mouse to manipulate and transfer data to the parent pc. For example, although ordinary glass is transparent, it nevertheless has very small irregularities that can be traced back with a laser. This allows you to use the surface of the glass table when working, even if it is not ideal. Meanwhile, if we put a modern optical mouse on the same glass, it will not be able to track our movements. Place a glass surface on a black desktop and the optical mouse, will still not be able to track the movements. Remove glass and optical mouse will start to work in a perfect way. Of course, the chance that constantly using a mouse on a glass surface is extremely rare, but this shows how the two lighting different processes in performance. LEDs will track deviations recorded in the top layer of the surface, while the laser can penetrate deeper to find more location-specific details. Optical computer mouse that works best on non-glossy surfaces and mats, and laser mouse can work on almost any glossy side or non-glossy surface.

The correctness and sensitivity

The problem with laser pc mice, is that they can be too precise, collecting useless information such as invisible particles on a surface. This leads to problems when driving at lower speeds, causing “jitter” of the screen. this error 1: 1 tracking is because of the useless data that is sent to the shared tracking computer that is being used. As a result, the cursor will not be displayed in exactly the same place at the time when the hand straightened it there. Although this problem has improved a lot over the years, laser mice are still not perfect, for example, when drawing details in Adobe Illustrator. however, jitter has nothing to do with the number of dots per inch that the mouse can track per second. instead, the jitter is attached to everything that is scanned using the laser, is collected by the sensor, and sent to the parent pc’s processor to display the cursor on the screen. To even out some of the jitter, you can put a fabric-based material, with a hard, dark surface underneath, on your desktop, so that the laser does not collect unnecessary or unwanted data. another option may be to reduce sensitivity. The resolution of the CMOS sensor on a pc mouse differs from that of a camera in that it is based on motion. The sensor consists of a certain number of physical points aligned on a square grid. The resolution is related to the number of individual images captured by each pixel as it moves across the surface. since physical points cannot be changed, the sensor can use image processing to split each pixel into a smaller area. however, all computer mice have a given physical resolution, and the increased sensitivity is associated with algorithms inside the sensor, so you can speed up the movement of the cursor on the screen, with the same physical movements. the closer you are to the base resolution, the less unwanted position data the sensor in a laser-based computer mouse collects. Simply put, lower sensitivity allows more precise movement.

Which is better?

It depends on the program and the environment. If you look at the Logitech G brand, you will notice that the Logitech is mainly focusing on the LED mouse when it comes to computer games. That’s because users usually sit at a desk and maybe even use a mouse pad designed for better tracking and grip on the surface. But the company also has laser mice, the same Logitech offers a small section of devices with a laser that is not focused on gamers. Another manufacturer, Razer, prefers laser technology because it provides higher sensitivity in games. In general, we do not believe that optical and laser technology itself is completely self-sufficient. our recommendation is more specific to office use. laser mice can be perfect when you are in a room, in the living room, lying on the couch, or browsing through facebook while sitting in a meeting. The performance can be whimsical given underneath the surface, but with a laser mouse you definitely have more options on any surface. A laser-based computer mouse is useful if you need to use your feet as a tracking surface, or when it is not in the office, but shiny furniture as the LED device absolutely hate. Most modern high-performance mice use a laser. But, as a rule, they are more expensive. While the laser is a more versatile technology, a decent optical mouse can handle less, as long as you use it on a flat, non-glossy surface. We hope this article has helped to understand at least a little better differences in technology in the most important accessories, and what kind of mouse you need, is also up to you.
