- About us
With every modern laser display system there’s already so much you can do with it, especially when used together with some state-of-the-art control systems such as Pangolin Beyond. Everything from simple single-colour static beams, waves and cones to a very complex and animated colourful shapes can be done and virtually any effect parameter can be changed - either in real-time or be programmed in advance and deployed as/when needed.
But creating and performing top-level laser displays is not only about laser programmer’s ability to come up with a set of cool effects, sequence them precisely and logically in the time-line and add transitions in-between. It’s often about having some other things available to make the shows better, more interesting or even possible at all. We call these “things” Laser Display Accessories and although they are only accessories, some of them can be vital for a successful show.
Laser Display Safety is the paramount of every true laser display professional and should be no.1 in terms of importance on their list. It’s the most basic criterium that ultimately defines whether the show will or will not happen or how it will be. And often, even the slightest detail, such as tiny overlap of laser radiation within the audience scanning restricted area, can compromise it all.
We offer a few accessories that can be used to help you to prevent some of the potentially dangerous situations during setup, testing and performance phases of your laser displays.
When used correctly, these lenses can greatly improve the safety levels of laser radiation in regards to audience scanning. They basically increase the divergence of the projected beam, making it bigger over the distance and therefore less dangerous. Six lenses of different thickness are available and they can be supplied as either individual lenses or set of six lenses in a plastic case.
4-Way masking plate
More than often it is required to limit the laser projection within a certain area. There’s no better and more reliable way to do that, than using metal for its impenetrable properties. Our set of four, nicely finished metal plates, fit all current Clubmax FB4, Atom, Spectrum, Spectrum OPSL and Spectrum RGBY systems (and their LD versions) and allow you to set the master zone of your projection so no beams will escape.
Laser Safety Goggles
A set of quality laser protection glasses is something everyone working with Class 4 lasers should have in their toolbox. They are great protection when aligning laser beams, servicing laser display systems or performing within the laser display area when the show is on.
Some basic, but pretty exact laser beam measurements under 1W can be done with this pocket laser-power meter. It’s a great tool for checking the power of single beams and laser reflections, such as those from static diffraction effects. The Coherent LaserCheck sensor aperture is 7mm in diameter which replicates the size of the human pupil.
Sometimes you may need to change the path of the beam half-way through, cover a larger projection area than standard scanners allow to or use some effects that can not be performed with typical laser scanning. Or maybe an artificial projection surface in mid-air or above a lake is required to project some of your amazing laser graphics onto. We offer a quality solution to every one of these situations.
Super-flat and front coated mirrors are used to bounce the beams in mid-air to different directions, allowing to work with laser beams in many unusual ways. Kvant Bounce Mirrors come in two types. The first one, with basic attachment bracket, is great for any general usage. The second one is fitted with precisely adjustable mount and allows for fine-tuning of the bounce direction - for example for long-distance beam targeting.
Another type of mirror is the Diffraction Mirror. Those look very similar to bounce mirrors, but instead of front coated reflection layer on the front, they are fitted with a diffraction foil. When the laser beam hit’s the mirror, it gets bounced off, during which the original beam is split into many beams and basic RGB colours. Two diffraction effects are available - Grid (Beam Burst effect) and Line (Finger Beam effect).
This special fish-eye lens provides a much wider scanning angle capability to any standard laser display projector when fitted correctly. The scanning on both axes is widened to 180° (from usual 60-90°) and that means that some pretty amazing and unusual laser effects can be performed. Just imagine a laser beam ceiling made of a single system installed in the centre of the room above the audience.
DiscoScan also allows a single laser display system to cover a much larger projection area.
With our model-specific DiscoScan lens bracket (sold separately), the DiscoScan lens can be fitted properly to all Kvant laser systems.
Our Laser Optical Bench is the laser output expansion module that is controlled via DMX and adds another layer of diffraction optical tweaks to any projected laser effect - changing it quite dramatically. For the Clubmax FB4, Atom 20, Spectrum, Spectrum OPSL, Spectrum RGBY and all LD systems there’s a single-layer Optical Bench available and it comes with 4 single diffraction gratings, one custom empty slot and one empty slot for standard laser projections when no Optical Bench involvement is wanted.
The brand new addition is Dual Optical Bench which works for Atom 20, LD 20 Atom and all Spectrum, Spectrum OPSL, Spectrum RGBY and LD Spectrum systems. This one offers two independent layers of diffraction grating effects (4x4), which can be combined and add a massive amount of diffraction options.
Even during the hot summer nights, some quality protection for all the great Kvant systems may come handy, especially for those unexpected showers and thunderstorms. Our lightweight protection covers against harsh weather are ideal for that - just slide it over the system, secure it so it doesn’t get blown off and it’s done. Rain won’t cause you any headache!
And for those times when uncompromising protection against any weather conditions is required, our hard-core enclosures will protect your Kvant equipment without hesitation from all the elements such as rain, snow, dust, wind, salt and hot and freezing temperatures.
There’s way too many cables in this world, but if you need more for your laser displays, we have them available. We offer ILDA, ethernet, E-Stop and power cables of high quality and in various lengths of up to 100 metres.
Visibility of Laser Displays
Virtually every indoor laser display (and many outdoor ones), or at least all the atmospheric shows, will require some amount of smoke or haze being present in the air to make the lasers visible. It’s safe to say that most professionals within Laser Display Industry will agree that quality hazers are a lot better for laser displays than smoke machines and that’s from about every single aspect: finer haze, longer dispersion times, water-based fluids, non-sticky residue and lower fluid consumption.
Over the many years of our own laser show production, we have tested different hazers for indoors, but only one became our favourite - the one we have been solely using since then - Unique hazer. And because we found it to be a great performer and extremely reliable, we decided to sell it to our customers too as well as the original high-quality haze fluids.
Laser graphics projections nearly always require some sort of projection medium to be projected onto or into. It is possible to project onto buildings, walls and hills, but sometimes an artificial projection “screen” needs to be used.
A nearly invisible projection screen is called gauze or laser gauze. Essentially it is very fine and thin meshing, that is almost invisible in dark, making it the perfect laser projection medium for 3D like mid-air indoor and outdoor projections. When set up correctly, the audience sees only the content being projected on this gauze. And if the content is programmed in 3D, then it also looks like 3D for the spectators.
Another category of projection media is water screens. There are two main types of water screens used for laser displays:
Shield - water is pumped under high pressure into a single powerful jet and gets sprayed out from the bottom upwards, creating semi-circle above the ground level. Such water screen can be about 20-30 meters wide and 10-20 meters high - that’s per a single jet. It is possible to use more jets in a line to create a single huge projection area. This type of screen is suitable for outdoors, to be installed on rivers, lakes, in the sea or on grounds which can absorb loads of water easily.
Curtain - water is pumped up into the rail that contains hundreds of small jets and disperses water evenly across the length of the rail segment. Each segment is 3 meters long and the segments can be joined together to create a wider projection screen. This type of screen can be also used indoors, as normally some water collection pool is built underneath the rails, making the water supply a closed circuit.
