Laser mice offer tracking performance that is twice of any optical mice

  Optical mice uses a red Light-Emitting Diode (LED) which is projected onto the surface (i.e.. mouse pad) for a sensor to read the pattern it lights up at a microscopic level through a lens, at a resolution of 800dpi.
  The optical sensor reads the image at a rate of about 1,500 times per second. The problem with this is sometimes differences in similar patterns are not easily distinguishable because of the lower resolution and power of the LED. Therefore it compromises the tracking accuracy depending on the surface (i.e.. certain mouse pads with certain patterns/surface textures).
  Laser is based on the same idea except it uses a narrow beam of light that is reflected off the surface producing an image with greater contrast that is captured by a higher resolution sensor (1600dpi) at a higher rate, of up to 6000-7000 times per second.

  Because of this advancement, laser can track where optical can’t, such as clear glass. Experts believe laser mice will take over optical mice the same way that optical mice wiped out the ball mice.

  By the above,with composing these two technology we have "SubLaser" that use a red Light-Emitting Diode (LED) which is projected onto the surface that is reflected off the surface producing an image with greater contrast that is captured by a higher resolution sensor (1600dpi) at a higher rate.

Means higher capture resolution with lower cost than Laser mouse.
