OEM Version

Description

The fiber-coupled Laser Diode Beam Sources of type 51nano-N (OEM version) have reduced power noise (typ. < 0.15 % 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 (with protective cap) or using the two modulation inputs for analog and TTL. The electrical cable is 1.5 m long. There are two possible supply voltages 5 V or 12 V. Other electrical cables and connectors on request.

More details on electronics type: HP, H.

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 connector (8°-polish). Fiber connectors with end caps are used for wavelengths < 635 nm. The fiber cables have strain-relief and protective sleeving (Ø 3 mm). Standard cable length is 150 cm.

Fiber Options:

Single-mode fibers with core-centered connector of type FC
Other connector types including DIN, AVIO, ST or E2000
Other fiber 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.
