Reduced coherence length: coherence length ≈ 300 µm
Reduced speckle contrast
Wavelength: 405 nm
Laser output power: 1 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-405-1-Y07-P-12-4-18-0-150 has a reduced power noise (typ. < 0.1 % 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 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.
