Lambda Fiber Stubs (4X5pack)

SKU: Codice123456789 Category:


Lambda fibers are provided in packs of five implantable fiber stubs. Fiber stubs are defined by the Fiber Specs (numerical aperture/core size and taper active length), Implant Length, and connector type.


To switch from your flat-end fiber with length L to the Lambda fiber, you need a Lambda fiber with Implant Length= L and to select the Active Length which best matches the size of your target area.

cLCF – Φ1.25mm, 6.4mm long ceramic ferrule

sLCF – Φ1.25mm, 6.4mm long ceramic ferrule with slot

mLCF – Φ1.25mm, 6.4mm long metal ferrule

cFCF – Φ2.5mm, 10.5mm long ceramic ferrule

mFCF – Φ2.5mm, 12.7mm long metal ferrule




*Nominal active length values refer to the whole-taper operation of Lambda fibers and are valid for blue (450 – 480nm) light emission and green (500 – 550nm) fluorescence collection. They only applies if the numerical aperture of the light launch/collection optical system matches the numerical apertures of the fiber stub and when using patch cords with the same specifications of the fiber stubs (both NA and core size).
