***** Butterfly packaged SLDs

ackages:

- fiber coupled – DIL, Butterfly; uncooled “minibut” packages

available upon request

 

* It is not allowed to exceed maximum output power or maximum

drive current, whatever happens first

** Center wavelength 670 nm is not guaranteed. Contact Superlum

representative if you require a tighter tolerance of center

wavelength.

*** Rated at minimum power, not guaranteed at maximum power of a

particular power category

**** Pseudo-depolarized versions (light is launched into the fiber at 45

degrees to the birefringent axes) are available upon request

The following part numbers should be used when ordering:

SLD-261-MP(a)-(b)-(c)-PD,

where:

(a) – power category (MP1 or MP2),

(b) – package type (DIL, DBUT, SBUT),

(c) – type of fiber — SM (isotropic) or PM (polarization maintaining).

Example: SLD-261-MP1-DIL-SM-PD.
