Difference Between Optical and Laser Mouse

So far, you must have known that there are 2 types of mice based on their working sensors, namely optical and laser. There is no denying that a mouse with a laser sensor has more advanced technology, but a laser sensor would not have been created without an optical sensor first. In this regard, do you really know the difference between the two?

If not, check out the following article which discusses the complete differences between optical sensors and laser sensors.

Difference Between Optical and Laser Mouse

1. The Beginning of Technology

Optical mouse technology was invented in 1980, but it took almost 2 decades to reach commercial success. Laser mice were first seen on Sun computer servers and workstations. Launched for day-to-day computing purposes in 2004 by Logitech.

2. Light Source

An optical mouse can use an LED or a series of photodiodes as its light source. The laser mouse uses an infrared laser which is invisible to the naked eye. However, when photographed using a CCD sensor, it will appear purple in the image. Laser and optical mice will appear similar in appearance, which one can identify by moving them up and down and comparing light sources. Optical mice usually have a light source that comes out red, white or blue, while laser mice have an infrared light that is usually invisible.

3. DPI and Mouse Sensitivity

Dots per inch or DPI abbreviated, is a measure of mouse sensitivity, can also be defined as the number of dots on the screen when the mouse is shifted 1 inch. The higher the DPI of a mouse, the more sensitive the mouse pointer is. Users can then feel the mouse pointer becomes more accurate and precise when using it. In general, laser mice are known to have a high DPI compared to optical mice. An optical mouse usually only has the highest DPI up to 800 while a laser mouse has a DPI between 2000 and 3400. For certain laser mice, the DPI varies and can be adjusted according to the user’s wishes.

4. Surface

Mouse is known to work on a soft surface or can be called a mousepad and most of the optical mouse requires a mousepad to function. The mouse does not function optimally when used on surfaces that shine or reflect light. However, this is not a problem for laser mice, because they can be used on hard surfaces such as tables or soft surfaces such as on a mattress.

5. Battery Consumption

When the user uses a wireless mouse, the optical mouse is not very good in terms of battery consumption, because it consumes more power so that it becomes more wasteful. Unlike the case with laser mice. The laser mouse has a good battery consumption rate, and can last up to 8 months for Li-ion type batteries. It is highly recommended to use a rechargeable battery for the wireless mouse to be economical and not to change the battery frequently.

6. User Experience

The optical mouse is proven to have a lot more development than the previous mechanical mouse. But there is no denying that the laser mouse has become the best for its users. For computer screens 17″ and larger, users are expected to have a mouse that has a high DPI, this is where laser mice are always preferred over ordinary optical mice. Also, laser mice are very popular with gamers because of their high accuracy and extra features that can be used with buttons. configured.

7. Price

Of the two types of mouse are available ranging from economical prices to relatively high prices when designed for gaming. Apart from laser sensor technology, laser mice usually have a better body shape which can also be coated with Teflon and other coatings for extended use.

With the above discussion, hopefully you will understand better what are the differences between an optical mouse and a laser mouse. May be useful.
