Features

The Laser Diode Beam Source of type 51nano-S-375-10-X23-P-12-4-18-0-150 has a reduced power noise, a reduced coherence length and a low speckle contrast.
  • Reduced power noise: typ. < 0.08 % of Po (RMS, Bandwidth < 1 MHz)
  • Reduced coherence length: coherence length ≈ 300 µm
  • Reduced speckle contrast
  • Wavelength: 375 nm
  • Laser output power: 10 mW
  • Single-mode fiber cable
  • FC APC connector (8°-polish) with end cap
  • Modulation analog and TTL
  • With interlock and key switch (conform to EN 60825-1)
Alternative: Laser Diode Beam Source 51nano-N (OEM version w/o key switch and w/o interlock) or with polarization-maintaining fiber cable

Description

The fiber-coupled Laser Diode Beam Source of type 51nano-S-375-10-X23-P-12-4-18-0-150 has a reduced power noise (typ. < 0.08 % of Po (RMS, Bandwidth < 1 MHz)), reduced coherence length (≈ 300 µm) and a lowered speckle contrast. 

Electrical features
The output power is adjustable using a potentiometer or using the two modulation inputs for analog and TTL. 

Fiber cable
The source is fiber-coupled to a single-mode fiber cable. As a result the beam profile is rotationally symmetric with Gaussian intensity distribution. The fiber cable is equipped with an FC APC type connector (8°-polish) and an end cap to prevent fiber damage. The fiber cable has a strain-relief and a protective sleeving (Ø 3 mm). Standard cable length is 150 cm.

Options:

  • Polarization-maintaining fiber cable
  • Other connector types including FC PC, DIN or AVIO, or E2000
  • Other fiber cable lengths
  • Incorporated vacuum feed-through

Laser safety
The laser safety is conform to IEC 825 / EN 60825-1. 

  • Interlock chain for the remote deactivation of the laser
  • Laser power-up is only possible using the key switch
  • LED status indicator for “Laser ON”
  • For a quick start the laser is shipped with a interlock connector type BC0106F-iLCK

An OEM version is available as type 51nano-N without key switch or interlock which is not conform to EN 60825-1.
