Tunable Edge Filters
-
Tunable edge filter is a customized product. It usually belongs to 2-port optical tunable filter product platform. Instead of using narrow bandpass filter in the 2-port tunable optical filter, the tunable edge filter utilizes a low-pass or long-pass interference filter. By changing the incident angle of the light beam, the cut-off wavelength will be tuned. Standard Tunable edge filters support C-band or L-band wavelength range.

LV Iron Core Harmonic Filters
-
Nonlinear loads such as power electronics based equipment and electric furnaces are sources of harmonic currents leading to harmonic distortion, which is one of the most important parameters for defining the power quality. Most of the commercial loads such as personal computers, photocopy machines, power supplies, and compact fluorescent lamps; and industrial loads such as AC and DC motor drives inject harmonic currents into the network that they are connected to.

Gas Filter Correlation CO Analyzer
Model T300U
-
Teledyne Advanced Pollution Instrumentation
The Model T300U Trace-level CO analyzer has been developed specifically to address the challenges of low level monitoring as required, for example, in the US NCore network. Using IR absorption with a Gas Filter Correlation Wheel, the T300U is designed to allow ultra-sensitive CO measurements while still meeting the requirements for use as a US EPA compliance analyzer.The optical bench is enclosed in a temperature controlled oven, dramatically decreasing instrument noise and drift. The objective and field mirrors in the sample cell are gold plated to maximize signal to noise performance, while a temperature-controlled Nafion dryer on the inlet minimizes water interference caused by ambient humidity changes. Periodically, the T300U seamlessly corrects its baseline by routing the sample through a heated catalytic CO scrubber. This Auto Reference function corrects zero drift and reduces the effect of interferences.

Real Time Digital Filters
-
Real Time Digital Filters can be used to filter a measured signal in real time. Filter characteristics can be defined by the user to meet the requirements of a specific application. Real-time digital filters are applied in the data conditioning phase. The filters are designed with a graphic design tool and then uploaded to the front-end for real-time calculation. The graphic design tool defines the filter performance vertical axis with a dB scale. The horizontal axis is defined as relative frequency.

Gas Filter Correlation Carbon Monoxide Analyzer
Model T300
-
The Model T300 measures low ranges of carbon monoxide by comparing infrared energy absorbed by a sample to that absorbed by a reference gas according to the Beer-Lambert law. Using a Gas Filter Correlation Wheel, a high energy IR light source is alternately passed through a CO filled chamber and a chamber with no CO present. The light path then travels through the sample cell, which has a folded path of 14 meters. The energy loss through the sample cell is compared with the span reference signal provided by the filter wheel to produce a signal proportional to concentration, with little effect from interfering gases within the sample. This design produces excellent zero and span stability and high signal to noise ratio, allowing extreme sensitivity. All T Series instruments offer an advanced color display, capacitive touch screen, intuitive user interface, flexible I/O, and built-in data acquisition capability. All instrument set up, control and access to stored data and diagnostic information, is available through the front panel, or via RS232, Ethernet, or USB com ports, either locally or by remote connection.The Model T300 comes with NumaView™ Software. NumaView™ Remote PC Software allows for a remote connection with virtual interface and data downloading capability to analyzers operating NumaView™ Software.

Gas Filter Correlation CO2 Analyzer
Model N360
-
Teledyne Advanced Pollution Instrumentation
The Model N360 measures carbon dioxide (CO2) by comparing infrared energy absorbed by a sample to that absorbed by a reference according to the Beer-Lambert law.The N360 uses Gas Filter Correlation (GFC) to overcome the interfering effects of various other gases (such as water vapor) that also absorb IR. The analyzer passes the IR beam through a spinning wheel made up of two separate chambers: one containing a high concentration of CO2 known as the reference, and the other containing a neutral gas known as the measure. The concentration of CO2 in the sample chamber is computed by taking the ratio of the instantaneous measure and reference values and then compensating the ratio for sample temperature and pressure. A nitrogen purge system is provided for the GFC wheel assembly to eliminate the effects of ambient CO2, if necessary.

Narrow Band Filters (Single Octave)
NANO-POLE® Series
-
The NANO-POLE® is designed for optimal size, DC consumption, RF power handling, insertion loss, signal purity and linearity. The NANO-POLE® provides a minimum center frequency step size of 10 MHz typically but can be modified based upon request. The NANO-POLE® requires a +3.0 V supply that typically draws 5 mA when not hopping. The supply voltage should be adequately filtered as noise present on this pin will influence the RF signal purity. The NANO-POLE® uses SPI control interface.
