Low Noise Laser Micro Focus Generator LNC-13MC+96CR

Low noise rotationally symmetric beam profile with Gaussian Intensity profile

The new low noise laser diode modules from Schäfter+Kirchhoff have reduced power noise, reduced coherence length and low speckle contrast as a result of internal RF-modulation. The low noise (< 0.1% RMS, @<1 MHz) and the mode-hopping free laser operation makes these laser diode modules ideal for particle measurements or advanced medical and biotechnological applications. Due to the reduced coherence length, speckle contrast might be lowered. This effect, however, becomes smaller for smaller spots.

  • Supply Voltage: 5V DC

Laser micro focus generators of type LNC-13MC…+96CR, use CircuLaser diodes (Blue Sky Inc.) with integrated micro-optics. The micro-optics transform the elliptical radiation emitted by the laser diode into circular radiation with a deviation maximum of 1:1.2.

The integrated electronics allow external modulation. The beamshaping optics define the optimum working distance and the focussing range. The chosen laser module determines the wavelength and the output power and, thereby, the laser safety class.
