Exclamation Laser Beam Width Calculations

For anyone interested here are a few calculations on Laser guns that shoot at certain distances in feet/inches. This will give you an idea of how hard it is for some jammers to jam a laser gun at very very short distances. These calculations will help you decide on the best place for installation of your jammer heads. Remembering that most officers shoot Center Mass shots first then head light shots. These numbers are dangerous under 500 feet.


Laser Beam width Calculations:


4500 foot shot= 162 inch laser beam width

3500 foot shot = 126 inch beam width

2500 foot shot = 90 inch beam width

2000 foot shot = 72 inch beam width

1800 foot shot = 64.8 inch beam width

1500 foot shot = 54 inch beam width

1000 foot shot = 36 inch beam width "3 feet wide"

500 foot shot = 18 inch beam width

300 foot shot = 10.8 inch beam width

100 foot shot = 3.6 inch beam width

50 foot shot = 1.8 inch beam width

I wonder how consistent this generic beam width data is amongst the various brands of laser guns? That would be some fun stuff to test.

MEM-TEK,

I think you've touched on an interesting point. All police lasers are not created equally.

I believe the beam pattern on the Stalker is more vertical (which may, in part, explain why it is so difficult to jam) and the LTI, I think, has a three beam column design.

Thay may also be the reason that some laser detectors struggle detecting some police lasers, as well.
