00:00This is a self-leveling cross-line laser level.

00:03We'll explore its components and how it works.

00:05A laser level projects a laser beam as a dot,

00:08horizontal line, vertical line, or cross line

00:11to help with alignment and leveling.

00:13Green lasers are more visible in daylight than red ones.

00:16This tool automatically levels itself even if the base isn't level.

00:20Before diving in, guess how far a line laser can reach.

00:24Watch till the end for the answer.

00:26The main components include the laser window,

00:29the threaded mount for tripods, the battery compartment,

00:32and the power switch.

00:34Inside, the laser module has a laser diode

00:36made of P-type and N-type semiconductor layers

00:39with an active layer where laser light is generated.

00:42The diode's ends are coated with reflective materials

00:45to create an optical cavity.

00:47When current flows, it produces photons

00:50that bounce inside the diode, amplifying the light.

00:53The light eventually escapes through one end,

00:56forming a laser beam.

00:58This beam is split and directed through lenses

01:00to create perpendicular lines.

01:02The main printed circuit board, PCBA, controls the functions,

01:06and a pendulum mechanism helps the device stay level

01:09by swinging in two axes.

01:11The pendulum is dampened by a magnet for stability.

01:14An electronic sensor on a secondary PCBA

01:17monitors the pendulum's position.

01:19If it moves beyond a set angle,

01:21it either shuts off or blinks the laser

01:23to prevent incorrect readings.

01:25The power switch controls the pendulum lock

01:28and the laser activation.

01:30The reach of a line laser varies.

01:32Indoors, it can go up to 30 meters.

01:34Outdoors, it's around 10 meters unless a detector is used,

01:37which can extend the range to over 50 meters.

01:40Green lasers are generally more visible than red ones.

01:43Let us know if you guessed correctly.
