PLEASE NOTE: We will only ship the Laser Interceptor to customers in Australia & New Zealand only. For all other countries, please check your local LI distributors.

If you are on this page, then no doubt you have already read about the Laser Interceptor. Unlike a radar detector that will alert you to a laser gun (by which time the laser gun usually already has your speed) a laser jammer will give you those few seconds you need to check your speed, adjust if necessary, before switching the jammer off.

Even though a radar detector has the ability to detect laser guns, on most occasions by the time you detect the laser gun, it's already too late - the gun has your speed. And that's assuming your detector does actually pick it up in the first place.

You see unlike a speed radar "beam", a speed laser "beam" is much more tightly focused, with very little of the "laser pulses" going past the car that is actually being targeted.

At 100m from the car, the diameter of the laser beam is approximately 30cm in diameter!!

At 300m from the car, the diameter is a mere 90cm

So if the laser is aimed at the centre front of your car (at your number plate), there is actually little chance of the beam spilling over your bonnet and hitting your radar detector mounted on the windscreen.

Here's a view from the front at the diameter of the laser beam at 100m, 200, and 300m

100m	200m	300m

You can see from this illustration, that at close ranges, the beam may not even strike your radar/laser detector when mounted on your windscreen (especially high next to the rear view mirror, which is a common mounting position), thereby failing to alert you when you car is targeted.

See our 2008 Laser Detection Test which shows this exact principle in play.

Here is a picture viewed from the scope of a LTI Ultralyte laser gun at 100m, 200m and 300m:

Note: the latter pictures above are blury because we've zoomed in on the photos to show you proportionally the same size car each time.

Again, you can see there is no dispute, the target area is smaller than the actual size of the car.  This is why you are not guaranteed to get an alert from your radar detector when your car is targeted at close range - as proven in our Laser Detection Test

So the first problem with detecting laser is that your radar/laser detector may not even go off.  The second problem is that even if your detector does go off, the laser gun usually has your speed in less than 1 second!

Laser guns work by transmitting a series of Infra-red (IR) pulses that hit yoru car, are reflected and recieved by the laser gun, and then a series of distance measurements can be taken since the speed of light is a constant.

By computing a whole bunch of distance readings over time, your speed can be calculated.

The laser guns used in Australia operate on either 100, 125 or 225 pulses per second (PPS), and require around 70 pulses to be transmitted, reflected and received for the 100/125 pps guns or around 180 pulses to be transmitted, reflected and received for the 225pps gun - in order to display your speed.

70 pulses from a 100pps gun means the laser gun (more accurately called a lidar gun) can aquire a vehicle's speed in 7/10ths of a second.

The Laser Interceptor requires installation, and is recommended to be installed by a professional. Contact us for suggested installers near you. We invite anyone in Perth to come and test their installation using our lidar guns.

The Guys of Lidar are one of the most respected, unbiased [read: not paid by a manufacturer to conduct a test of their product] group of radar detector & laser jammer testers in the USA.

Each year the group of enthusiasts meet and test different products for the purpose of measuring the performance of different models against one another.

They do not charge manufacturers to attend with their products (as SML do) nor are they paid by a manufacture (as does / did at one stage) the other main radar detector reviewer in the US.

In July of 2008, the Guys of Lidar conducted their annual laser jammer test, which was their second year of testing the Laser Interceptor

Here is the Guys of Lidar's July 2008 laser jammer test results:

Here is the Guys of Lidar's March 2007 laser jammer test results:

DelonixRadar conducts our own radar detector and laser jammer tests, to verify claims made by all radar and laser manufacturers. We own a vast array of test equipment including 3 lidar guns, K and Ka-band radar guns, as well as a Spectre IV+ radar detector detector.

Here were the results from our November 2008 laser jammer test:

Key for results tabled below:

• Figures represent time in seconds jammed before a speed reading was obtained.
• Jammer successfully jammed lidar gun for 4 or more seconds = green
• Jammer jammed lidar gun between 2 & 4 seconds = orange
• Jammer jammed lidar gun for less than 2 seconds = red
• Instant punch through (jammer had no effect) = IPT
• Not detected by the jammer = ND
