51nano-S-940-15-C07-P-5-2-18-0-150

The fiber-coupled Laser Diode Beam Source of type 51nano-S-940-15-C07-P-5-2-18-0-150 has a reduced power noise (typ. < 0.08 % of P_o (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 ≥ 23 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). 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
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.
