  • Reduced speckle contrast
  • Wavelength: 375 nm
  • Laser output power: 10 mW
  • Polarization-maintaining fiber cable
  • FC APC connector (8°-polish)
  • Modulation analog and TTL
  • OEM version w/o interlock and w/o key switch
Alternative: Laser Diode Beam Source 51nano-S (with key switch and interlock) or with single-mode fiber cable

Description

The fiber-coupled Laser Diode Beam Source of type 51nano-N-375-10-X23-P-12-4-28-0-150 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 polarization-maintaining fiber cable (standard, polarization extinction ratio = 21 dB). 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:

  • Single-mode fiber 
  • Core-centered (single-mode only)
  • Multiple fiber output cables (51nanoC, single-mode only)
  • Other connector types including FC PC, DIN or AVIO, or E2000
  • Other fiber cable lengths
  • Incorporated vacuum feed-through

Laser safety
This OEM version has no key switch or interlock and is not conform to EN 60825-1.
It can be operated conform to EN 60825-1 by using a switchbox.
As an alternative, a version with key switch and with interlock (conform to EN 60825-1) is available
as type 51nano-S.
