UV, Violet, Blue, Green, Yellow, Red NIR LED Fiber-Coupled LED Light Sources |
Introduction |
|
Prizmatix Silver-LED fiber-coupled LEDs provide high power continuous (CW) low noise output as well as fast pulsed operation from optical fiber.
Silver-LEDs are available at deep UV, UV, Violet, Blue, Green, Yellow, Red or NIR. Fiber Coupled LED light source modules are ideal for use
with high NA optical fibers. These fiber-coupled LEDs are effective replacements of fiber-coupled lasers in many applications,
such as spectroscopy, photochemistry, NMR as well as illumination and curing.
The TTL input enables external triggering. The Analog input (0-5Vdc)
enables control of output power from computer equipped with digital to analog module (D/A).
Silver-LED is ideal for use with various fiber optic spectrometers in continuous,
strobe or external triggering measurement mode.

Some Research Papers with Reference to Prizmatix's Fiber-Coupled LEDs
Title:
CXCR4 promotes B cell egress from Peyer's patches
Peyer’s patches (PPs) play a central role in supporting B cell responses against intestinal antigens,
yet the factors controlling B cell passage through these mucosal lymphoid tissues are incompletely
understood. We report that, in mixed chimeras, CXCR4-deficient B cells accumulate in PPs compared with
their representation in other lymphoid tissues. CXCR4-deficient B cells egress from PPs more slowly
than wild-type cells, whereas CXCR5-deficient cells egress more rapidly. The CXCR4 ligand, CXCL12,
is expressed by cells adjacent to lymphatic endothelial cells in a zone that abuts but minimally
overlaps with the CXCL13+ follicle. CXCR4-deficient B cells show reduced localization to these CXCL12+
perilymphatic zones, whereas CXCR5-deficient B cells preferentially localize in these regions. By
photoconverting KikGR-expressing cells within surgically exposed PPs, we provide evidence that naive B
cells transit PPs with an approximate residency half-life of 10 h. When CXCR4 is lacking, KikGR+ B
cells show a delay in PP egress. In summary, we identify a CXCL12hi perilymphatic zone in PPs that
plays a role in overcoming CXCL13-mediated retention to promote B cell egress from these gut-associated lymphoid tissues.

Optional Accessories
Fiber patch cords:
Various fiber optic patch cords are available for use with the 3-LED or 5-LED products.
Most popular patch cords are 1000 / 1500 / 2000 micron core diameter Polymer Optical Fibers (POF)
terminated by optical SMA connectors on both sides. Prizmatix can provide
Stainless Steel tube at one end of the patch cord instead of the SMA connector.
This configuration is more convenient in some applications. See more details at:
https://www.prizmatix.com/dev/Custom-Fiber-Optic-Assemblies.htm
|
Fiberoptic Collimator:
Collimators are required to
generate a parallel beam of light out of the naturally
diverging light emission from an optical fiber.
Prizmatix collimator
is designed to collimate High NA fibers (up to 0.53), such as Hard Polymer Clad fibers
and Polymer Optical Fibers (POFs).See more details at:
https://www.prizmatix.com/optics/Collimator.htm
|
 |
Fiber Bundles:
To combine outputs of multiple LEDs a Y-shaped fiber bundle with two or more input
branches can be used. Prizmatix can help to configure and build custom fiber bundles
for specific applications.See moree details at:
https://www.prizmatix.com/dev/Custom-Fiber-Optic-Assemblies.htm.
|
Special Bundles:
For spectroscopy application special fiber optic bundles are very important. Special care
must be addressed to eliminate possible cross link between the excitation and the collection fibers. Seemore details at:
