Compact stabilised solid state lasers from CrystaLaser.

The most reliable Solid-State technology available, all in an ultra-compact footprint. The Direct Series lasers cover a variety of wavelengths suitable for laboratory research as well as OEM applications. The OEM option integrates the control electronics within the laser head, further reducing size.

Features:

  • Wavelength 375 nm to 1550 nm, power up to 1 W
  • Low noise and SLM
  • Excellent pointing stability and power stability
  • Ultra compact OEM package
  • High speed modulation up to 200 MHz
  • Free space and fibre delivery system

 

Applications:

  • Holographics
  • Flow cytometry
  • Fluorescence
  • Microscopy
  • Confocal microscopy
  • Raman Spectroscopy
