This tool helps in specifying the divergence of a laser system based the laser spot size of the laser projection, the distance of the laser aperture to the projection surface and the initial diameter of the laser beam at the laser aperture.

It is often difficult to determine the divergence of a laser system, especially if there is not much experience in doing this. This Divergence tool is a good helper in this case.
Remember to consider if the divergence shall be specified as full-angle divergence or half-angle divergence. Whereas the Laserworld Group usually specifies full-angle divergence values, some manufacturers rather give half-angle divergence values.


Please fill in all values, otherwise the Divergence cannot be calculated properly

What is the SZED?

The SZED specifies the distance from a laser source after that flashblindness can occur when the laser beam hits a human eye. This is specifically important if it comes to aircraft safety: Even though the laser may not be strong enough to be hazardous after a certain distance (NOHD distance), it can still cause flashblindness to pilots or aircraft personnell. The SZED is calculated per wavelength, as human eye perceives the brightness of wavelengths differently.

How to use the SZED online calculator:

It is mandatory to enter the divergence of the laser, as it significantly influences on the flashblindness distance. Please also specify at least the power values of one color source. For RGB lasers, please enter the power values for all three color sources. The tool uses correction factors per color to calculate the SZED. These wavelengths are assumed per color: red: 633nm; green: 532nm; blue: 445nm. Even though the laser you have on hand may have slightly different wavelengths (maybe 520nm for green or 450nm for blue or 650nm for red), the results from the calculation should be very similar.


Please fill in the required values, otherwise the SZED cannot be calculated properly

What is the NOHD (or N.O.H.D.)?

NOHD is the abbreviation of "Nominal Ocular Hazard Distance". It specifies the distance from the laser source source at which the intensity of a single laser beam becomes safe by not exceeding the MPE (Maximum Permissible Exposure) any more. The laser beam is considered to be dangerous if viewed from a closer distance than that.  

THIS TOOL IS NOT SUITABLE FOR CALCULATING THE SAFETY OF A LASER SHOW DISPLAY! IN SHOW LASER INDUSTRY IT IS ONLY RELEVANT FOR DETERMINING THE SAFETY DISTANCE FOR OUTDOOR LASER DISPLAYS WITH SINGLE BEAMS, WHICH IS A VERY RARE OCCASION, AS THE BEAMS ARE USUALLY DEFLECTED AND MODULATED IN OUR INDUSTRY!

Laser shows with deflected and modulated laser sources are considered safe at very much closer distances, usually only several meters!

Like the MPE, the NOHD depends on several parameters :
  • The output power of the laser
  • The beam specifications diameter at aperture and divergence
Under certain circumstances special optical instruments may be used for viewing the laser from farer distance. This fact must be considered when determining the NOHD. This calculator does not repect any optical instruments at all, as it's highly unlikely that this needs to be considered in shol laser industry. However, it's up to the operator's respondibility to do a proper safety risk assessment.

This NOHD online calculator is provided as is. Laserworld cannot be held liable for the results nor do we guarantee the correctness and accuracy of the results. The NODH calculator is only applicable for laser sources in cw operation mode and only valid for the wavelength span from 400 to 700nm - which are common parameters for show laser systems.

What do I need the NOHD calculation for?

The NOHD value depends on the characteristics of the laser systems used. In show laser industry this value can be requested by authorities to determine potential risks for aviation. As there are pretty high power laser systems in the market, and as they are very accurate as well, these lasers can reach over very long distances. Even though the MPE values are extremely low for what human eye could actually stand in terms of immission of optical radiation, some authorities require the NOHD.
The calculator above can help you in determining this Nominal Ocular Hazard Distance with ease. Be aware that the divergence heavily influences on the actual power over distance.

The evaluation of the beam quality of a show laser system seems to be simple, however there are many aspects to be looked at more in detail to not get fooled.
It is important to know more about facts and figures.

Many of our show laser light systems can be operated in DMX512 mode. As DMX is a serial signal with a special protocol, it is possible to apply a certain start address to every system in the line.

This calculation tool shall help you in finding the right dip-switch settings for a certain DMX address. The dip switches are set according to binary calculation meaning that every dip switch can feedback only the values 0 and 1. The calculation is comparably simple: Every dip switch has the value 2n where n is the number of the dip switch. First dip switch is 0 (computers start counting from 0, not from 1), so when it's switched on it says 20 = 1. Dip switch 2 has the value 1 if switched on, so it is 21 =2. Third dip switch has 22 = 4, fourth 23 = 8.
To Set a value you first have to find the highest number that fits the value, then you add up smaller values.

Example:
DMX512 value 11 shall be set:
1. Highest number that fits is 23 = 8
2. Second highest number is 21 = 2
3. third highest number that fits is 20 =1
So setting would be: 11010000

If it comes to laser installations the question of possible scan angles in combination with graphics size and distance arises.

- So how big will the picture be after a certain distance with my laser?
- What scan angle do I need to get a certain picture size after a defined distance?
- What projection distance do I need to choose to create a laser projection in a certain size with predefined scan angle?

This calculation tool makes it easy for you:
Just enter two values and the third one will be calculated. With this it is very easy to determine the right solution. Please remember that you may use whatever unit you want for the lengths, but they must be the same. So both meters, inches, feet etc.. Different units will give wrong results.


What a pity - you need to enter at least two values so we can calculate!
Maximum deflection angle of scanner system: °
Distance between laser and projection surface:
Size of the projection:

Laser Show References

Many references of laser shows and multi-media shows where laser systems manufactured by the Laserworld group came into action accumulated over the past years, so we documented them in pictures and videos in our portfolio section. Of course, these references only show a small part of the laser shows and multi-media shows our partners have done throughout the years, as many of our customers did not want us to show their project in our references – mainly as these were commercial laser applications or corporate laser shows, which were not meant to be publicly shown. Nevertheless we prepared a good number of references, and we keep on adding more.
The partners of the Laserworld Group did laser shows and multi-media projects at many different occasions and for many different applications. Most common places laser shows are displayed at nightclubs, festivals, amusement parks and at corporate shows. Also many famous artists and musicians rely on laser show and multimedia support for their stage shows. Besides that, lasers were used at weddings, for product presentations or for architecture and mapping.
