K40 Laser Defusers

Complete protection from police laser speeding tickets

Since introducing the world’s first police laser gun countermeasure device in 1994, K40 Electronics has evolved the high-performance Laser Defuser line with industry-leading innovations.  Choose the laser ticket protection that’s right for you, your vehicle and the way you drive with the Laser Defuser g5 or the Laser Defuser Optix.

Radar System Compatibility – All K40 Laser Defusers integrate with any K40 remote radar system, thereby utilizing a single warning display (instrument-mounted LED(s)) for both radar and laser alerts.

Laser Defuser g5 – Features

Each Laser Defuser g5 transponder contains five infrared laser detection diodes, 10 powerful laser jamming diodes, and a fly-eye lens for enhanced laser gun detection and protection.

  • Maximum Coverage Protection: The in-vehicle sync interface can fire up to four Laser Defuser g5 transponders simultaneously for superior detection and maximum jamming output.
  • Only You Know You’re Protected:  The Laser Defuser g5 generates a commonly experienced error code on police laser guns.  This is an important feature in states where the use of laser jammers is restricted.
  • License Plate Mount: Ideal for protecting the rear of a vehicle, the license plate mount strategically positions the Laser Defuser g5 where police laser gun operators are trained to target while providing a stealthy, yet OEM external appearance.

 

 

Three User-Selectable Transmit Modes

  • Constant Transmit: The Laser Defuser g5 will continuously transmit a signal for the duration of the laser encounter.
  • Pulse Transmit: The Laser Defuser g5 will transmit a signal for 10 seconds so you can safely reduce speed. The system will then shut off for 30 seconds. At this point, the laser targeting police officer has obtained a slower speed reading for your vehicle while eliminating the suspicion of “jamming” where the use of laser jammers is prohibited.
  • Receive Only: For notification only. No signal will be emitted.
Laser Defuser Optix – Features

Each Laser Defuser Optix transponder contains a powerful Nanostack™ technology pulsed laser diode for high optical output power and outstanding reliability.

  • Ultra-Compact Footprint for Discreet Placement
    Sized similar to a slim automotive key fob or USB flash drive, the Laser Defuser Optix compact footprint allows easy and discreet installation into grilles and other tight spaces.
  • Updateable to Ensure Optimum Performance
    The in-vehicle sync interface controller features a USB port so its system software can be updated as new police laser gun technology emerges.
  • Maximum Coverage Protection
    The in-vehicle sync interface can fire up to five transponders simultaneously for superior detection and maximum jamming output.

 

 

Three User-Selectable Transmit Modes

  • Constant Transmit: The Laser Defuser Optix will continuously transmit a signal for the duration of the laser encounter.
  • Pulse Transmit: The Laser Defuser Optix will transmit a signal for 5 seconds so you can safely reduce speed. The system will then shut off for 30 seconds. At this point, the laser targeting police officer has obtained a slower speed reading for your vehicle while eliminating the suspicion of “jamming” where the use of laser jammers is prohibited.
  • Receive Only: For notification only. No signal will be emitted.

K40 Laser Defuser g5 Review – Lab style and road tests. Results: As Advertised!

January 2014 Review.  A little history before getting to the fun stuff.

Another generation of the well known Defuser brand has made it to the market.  Since 1996, K40 has been developing infrared speed detection inhibiting ‘plate frames.’  The jamming techniques have changed over the years(Brute/white noise to pulse match), but the customer service has…Read more

I don’t know what was up today but I must have been lasered ten times by NJ State Troopers in my 100 mile journey today. Not one of them came after me.

LIDAR stands for “light detection and ranging.” A LIDAR/LASER gun transmits a pulsed rate of light at an object, the object reflects the pulsed light, and the instrument analyzes the speed of the reflection. Through this analysis, the speed and distance of the object can be determined. At typical target ranges of 800-1000 feet, a police laser gun beam measures between 18? and 36? in diameter. This narrow, infrared, monochromatic, one milliradian laser emission does not scatter like a police radar signal, so there is no advance warning to police laser use.

Unlike radar, laser guns give no advance warning. If you are targeted while speeding and you do not have a Laser Defuser (jammer), you will receive a speeding ticket. Laser is very short-range. Laser gun ranges vary from approximately 800-2000 feet. An officer cannot be moving/driving while shooting laser, and laser cannot read through glass. Laser can target and acquire a speed on a specific vehicle in a pack of cars. Radar is a radio frequency that leaves the gun and spreads out over a great distance. This is why radar detectors can pick up police radar from distances up to 10 miles away. Officers can drive and obtain radar speed readings on vehicles while they are in motion.

Both Laser Defuser models detect the laser light signal transmitted by a police laser gun and notify drivers with a unique audible and visual alert hidden discreetly inside the vehicle’s interior. Simultaneously, the Laser Defusers transmit a return infrared light beam at the same frequency as police laser so the police laser gun cannot get a speed reading. The main difference between the two models is the Laser Defuser g5 uses 10 LED jamming diodes whereas the Laser Defuser Optix uses a single pulsed laser diode.

Laser guns are capable of measuring a vehicle’s speed in less than one second. By the time a laser detector alarms, it is already too late. Only laser jamming countermeasures like Laser Defusers can provide drivers with the time needed to react and safely reduce their speed to avoid a costly ticket.

Yes. The Laser Defuser systems are designed to detect and deactivate police laser signals only. Therefore, we recommend complementing a Laser Defuser g5 or Laser Defuser Optix system with any K40 Electronics portable/window mount or custom-installed radar detector to create a complete police radar and laser countermeasure solution.

Yes. The Laser Defuser g5 and Laser Defuser Optix have been designed to allow integration with preexisting K40 remote radar detection systems. This integration eliminates installing an extra warning light or speaker to receive alerts from the Laser Defusers.

K40 recommends two Laser Defusers be installed on the front of every vehicle. For optimum placement for your specific vehicle, you should consult with your installing dealer and/or call us at 800-323-5608. The Laser Defuser g5 comes pre-installed in a license plate frame for a factory looking rear laser protection solution. In all mounting locations, front or rear, Laser Defusers should be mounted parallel to the ground (not pointing up, down, or to the side) with a clear, unobstructed view of the road for maximum effectiveness.

Since the Laser Defusers emit an infrared light beam that does not interfere with radio waves or any devices regulated by the Federal Communications Commission (FCC), there are no federal laws banning the use of laser jammers. Some states do restrict the use of laser jammers, so K40 recommends checking your state statutes for specific information.

We have absolute confidence in the performance of our products, and you should never get a speeding ticket when they are operating and used properly. In the rare event you should receive a speeding ticket in the first 12 months of ownership, we’ll pay any and all fines (excludes attorney fees and/or insurance premium increases as well as tickets issued in school zones, construction zones, and/or when DUI or DWI is involved). No questions asked.

It’s the best, most comprehensive guarantee in the business, and we make it with the utmost confidence.
