note A
Due to Advanced Optical Correction technology used in Kvant systems, the real power output of each laser module installed within the system may slightly differ from its specification. This doesn't affect the total guaranteed power output of the system.
note B The beam divergence total is calculated as an average arithmetic value of all individual colours. The divergence of each colour is calculated as:
1. FWHM of the beam cross-section for round beams, or
2. The arithmetic average of the beam's horizontal and vertical divergence for all rectangular beams.
Show Full Specification


Our good old Spectrum went through wast number of changes and improvements throughout the years of its existence.

The current 2020 version of Spectrum is all that success-focused laser display professional needs for large scale outdoor shows, and for whom failure is not an option.

The Spectrum range (including LD Spectrum, Spectrum RGBY and LD Spectrum RGBY product lines) represents power, precision, robustness, cutting edge technology and top of the range features, which are often unique and make the Spectrums what they are! Bright, reliable, fast-scanning and a pleasure to work with.
The whole Spectrum family is based on identical and field-tested construction, making it suitable for intense touring, permanent installs, and daily hire business.

LD 33 Spectrum RGBY is our most powerful, top of the range "super-laser" - the one that will make you the brightest!

With installed 33 Watts of total laser power, an extra 5W/577nm yellow OPSL head inside for doubled total luminosity, and together with special Low Divergence optics which intensifies the output even further and beyond, this LD 33 Spectrum RGBY system is way superior to others. In fact, it is brighter than anything else we've seen so far, no exception!

LD 33 Spectrum RGBY will take anything you throw at it. Festivals? Tours? Theme parks? So be it! There's just nothing better out there for the job.

Highlights of the Spectrum:

  • extreme brightness thanks to the extra 5W/577nm yellow laser and Low Divergence output optics; comparable with standard 80-100 Watts RGB systems
  • 30kpps Saturn9 scanning
  • Colour Balance display mode
  • robust construction
  • optional Motorised Dichroic Filters for quick and easy beam alignment
  • integrated Pangolin FB4 control interface as standard with Pangolin QuickShow 4.0 laser control and creation software included
  • direct control from most lighting consoles over the ArtNet

Every KVANT laser system is delivered with a Quality Control Certificate. The certificate includes the power output measurement of each laser wavelength within the system.

Pass Card Integration


PASS (Professional Audience Safety System) is a safety device that helps monitor laser power, scanner signals and other projector related parameters, to ensure your laser show is safe.
PASS is primarily used to ensure the safety of audience scanning style laser shows, where the laser beam comes in direct contact with people watching the show.

Motorised Dichroic Filters for Easy Colour Alignment


Motorised dichroic filters offer a quick and easy colour (beam) alignment without need to get into optical compartment of the laser system. They can be controlled with either built-in FB4 interface, remotely via Pangolin Beyond, or manually in case of emergency. Please note, that for the control from Beyond, a Beyond licence is needed.
