Laser fiber light guide for sample ablation by Siskiyou

Siskiyou FLG-SMA fiber light guide

The FLG-SMA fiber light guide from Siskiyou (Grants Pass, OR) for light stimulation, uncaging, and sample ablation features a 2 m fiber cable with a 600 µm core and SMA connectors to maximize coupling efficiency across a wide range of input powers and wavelengths. A 0.375" diameter tube with an input asphere collimates the divergent output from a fiber input, and the output lens focuses the light to a diffraction-limited spot 16.5 mm from the tip. As a standalone item, it mounts in a fiber coupler or an optical mount for free-space coupling applications.

New External Focused Laser Guide for Life Science from AMS Technologies

AMS Technologies introduces the FLG-SMA fiber light guide from Siskiyou which is ideal for introducing a focused laser spot into many experiments, notably onto a sample under observation on a microscope – without going through the microscope optics.

The 2-meter fiber cable has a 600 micron core to maximize coupling efficiency across a wide range of input powers and wavelengths.  It's ideal for light stimulation, uncaging, and sample ablation.  Industry standard SMA connectors are supplied on the input end of the FLG, and the output end of the FLG-SMA/2.

The FLG tube contains two aspheric lenses – the input asphere collimated the divergent output from a fiber input, and the output lens focuses the light to a diffraction-limited spot 16.5mm from the tip.  The tube is 0.375" diameter for easy mounting in a wide variety of micromanipulators, while the long working distance allows for easy placement next to a microscope objective.  Depending on the input angle, the spot will have varying ellipticity on the sample.

The FLG-SMA/2, when connected to out CBH-1, provides a simple connectorized output from a microscope for coupling to a spectrometer, photon counter, or other connectorized object.  As a standalone item, it can mounted in our fiber coupler or an optical mount for free-space coupling applications.  Used as an input, it allows the introduction of a laser source to a microscope, via the microscope optics, for a variety of applications.
