Features
Laser Diode Beam Sources of type 51nano-S have reduced power noise, reduced coherence length and a lowered speckle contrast.
- Reduced power noise: typ. < 0.15 % of Po (RMS, Bandwidth < 1 MHz)
- Reduced coherence length: Coherence length ≈ 300 µm
- Reduced speckle contrast
- Various wavelengths from 375 nm to 1550 nm
- Laser output power up to 30 mW
- Polarization-maintaining fiber cable (Polarization Extinction Ratio PER ≥ 23 dB (for λ < 600 nm ≥ 21 dB))
- FC APC connector (8°-polish), optional DIN AVIO or E-2000, end caps for wavelengths < 635 nm
- Modulation analog and TTL
- With interlock and key switch (conform to EN 60825-1)
- Beam profile is rotationally symmetric with Gaussian intensity distribution
