Green Laser Vs Red Laser Power

So are they really worth the trade off.

Green laser vs red laser power.

Red vs green vs blue vs yellow by wesley fenlon on aug. Red green blue and yellow pointers all have unique differences and choosing which kind is right for you can be a challenge. Outside of the obvious difference in color there are significant differences between red and green laser levels. Green lasers are more complex.

While a green beam appears brighter to the human eye and often produces a crisper point or line it is also more expensive and consumes more battery power. This will lead to less total operation time compared to a red laser level. 30 2010 at 9 20 a m. Recently a green laser was introduced to the laser sight family.

I wanted to put the theory to the test. Green can be used inside or out but green is much. Know your laser spectrum. Green at 532 nm the diagram below compares a 5 milliwatt red laser 633 nanometer wavelength with an equivalent 5 mw green laser 532 nm wavelength.

Below mentioned are the reasons why you should and shouldn t choose both red and green beam laser levels. These laser levels use more power. So producing the same power output as a class 3r green beam. Green laser pointers appeared on the market around 2000 and are the most common type of dpss lasers also called diode pumped solid state frequency doubled dpssfd they are more complex than standard red laser pointers because laser diodes are not commonly available in this wavelength range.

The human eye is more sensitive to the colour green compared to red but this not necessarily mean that a green laser will appear brighter for you. Just looking at the red and green lasers side by side on the wall in my house the green laser did appear to be brighter. On average a green beam laser level costs at least 20 to 25 more than its red. Red lasers are suitable indoors around the clock or outside from dusk to dawn.

Ask any worker and he d tell you that green laser levels are more expensive than their red counterparts. Knowing which to pick is dependent on how you intend to use your laser level as well as your budget. As you can see the red laser has a visual interference hazard distance that is about half of the green laser. When comparing red and green lasers of the same power which appears brighter is largely determined by the colour and texture of the.

Green lasers drain batteries quicker and at least for now they re also more expensive to manufacture. Building a green laser requires a special 808 diode a second infrared laser crystal and a frequency doubling crystal and these parts must be carefully aligned to produce the green laser image. Green laser level operates at a higher temperature this makes the green diodes more prone to damage. For this reason green lasers are more complicated slightly larger and more time consuming and thus expensive to build.

The downside is the power requirement. Red at 633 nm vs.
