The fiber-coupled high power UV, Violet, Blue, Green, Yellow, Red and NIR LED multi wavelength light source modules are
effective replacements of lasers and lamps in many applications, such as spectroscopy, bio-illumination and point curing.
Currenty available are FC2-LED, FC3-LED, FC5-LED, FC8-LED and FC10-LED models. Single channel module is also available (see
Silver-LED ).
Each LED has separate current driver with discrete controls.
The driver supports CW and pulsed operation mode.
Each channel manual power control is provided by 10 turns potentiometer with counting dial. The external Analog Inputs provide a simple way of LED output power control
by computer through DAC (Digital to Analog Converter).
The external TTL inputs enable external triggering of each LED separately.
Both Analog Inputs and TTL inputs are optically isolated with fast opto-couplers.
The fiber coupled LED sources are ideal for use with various fiber optic spectrometers in continuous, strobe or external triggering measurement mode.
Currently the multi-wavelength fiber coupled light source modules can include any combination of
wavelengths from the table below.

Title:
Elucidation of the unsymmetrical effect on the piezoelectric and semiconducting properties of Cd-doped 1D-ZnO nanorods
Herein, we report the unsymmetric effect on the functional (piezoelectric and semiconducting)
properties of cadmium-doped 1D-ZnO nanorods (NRs), which have a higher ionic radius (0.97 Å).
The growth of Cd-ZnO NRs, which have a hexagonal wurtzite structure without any secondary CdO
phases, along the c-axis was confirmed by the XRD patterns, and oxidation states observed from
XPS analyses verified the diffusion of Cd2+ into ZnO NRs. A one-fold reduction in the piezoelectric
properties was determined by the fabrication of a nanogenerator, and enhancement in the
semiconducting properties was studied using an Ag/Cd-ZnO NRs/Ag device with various wt% of
Cd doped into the ZnO NRs lattice. Cd-ZnO NRs improve the photogenerated charge carriers
(Iph ∼ 330 μA) compared to pure ZnO NRs (Iph ∼ 213 μA), obtained at a bias voltage of 10 V,
a wavelength of 365 nm and a light intensity of 8 mW cm−2. The Cd-ZnO NRs (1 wt%) based sensor
shows good photoresponse with a detectivity (D*) limit of 1 × 1011 cm H1/2 W−1 compared to that
of pure ZnO NRs (D* = 5.4 × 1010 cm H1/2 W−1). We also demonstrate a self-powered UV sensor
(SPUV-S) connected parallel to the ZnO NRs based nanogenerator as an independent power source
to drive the Cd-ZnO NRs UV sensor. The low-temperature hydrothermal synthesis of Cd-ZnO NRs is
simple, cost-effective, and scalable for industrial applications.

Optional Accessories
Fiber patch cords:
Various 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.

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. See more details at:
