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 lasers 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 30 Spectrum (Low Divergence version of Spectrum 30) is the most powerful version of all LD Spectrums. It comes fitted with a special optics that keep the beam divergence at incredibly low 0.48 mrad (measured at a full angle), resulting in a powerful and unusually bright beam over distance. And although the initial beam size is a bit bigger than on standard systems, with Saturn9 scanners the 30 Kpps speeds and drawing precision are easily maintained.
LD 30 Spectrum lasers are suitable for long-range outdoor projections.

Highlights of the Spectrum:

  • a lot brighter than a standard non-LD system
  • low divergence of only 0.48 mrad at a full angle
  • 30 Kpps 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.
