Long Light Source
LM-A
The long light source is compatible with the LM-101 or the LMC-20. The light is supplied with a 50 watt tungsten halogen convection cooled light source which provides suffcient energy for use with narrow band pass filters or monochronomators in the wave length range of .35 to 2.5 microns. The light beam is chopped at 200 hz by a quiet, vibration free, synchronous motor. The housing also contains a secondary LED light source and detector for synchronization of the amplifier, plus an electro-mechanical shutter to block the light output when the instrument is zeroed. An internal collimating lens produces a narrow beam (<1") so the LM-A can be used in bell-jar and large coating systems.

SparkFun Current Sensor Breakout
INA169
The INA169 is a “high-side current monitor,” which means that you place a resistor (a “shunt resistor”) on the positive power rail and the INA169 measures the voltage drop across that resistor. The INA169 outputs a small current based on the measured voltage drop. If you place a resistor from the output of the INA169 to ground, you can measure the voltage at the output.

DC Blocks
Coaxial DC Blocks allow the transmission of RF signals while blocking DC signals, usually using a blocking capacitor. We feature SMA DC blocks, 2.92mm DC Blocks, 1.85mm DC Blocks, BNC DC Blocks, TNC DC Blocks, and Type N DC Blocks. DC blocks can block the inner conductor, outer conductor, or both; hence there are "inner" dc blocks, "outer" dc blocks, and "inner/outer" dc blocks. These Coaxial DC Blocks are frequently used in Satellite Systems where a control voltage is passed along with the RF signal, and the coaxial dc block protects equipment. The BNC DC block uses a precision bnc to get to 4ghz. The C0927 SMA DC Block uses dual parallel capacitors to achieve its broad bandwidth, its ideal for EO & NRZ systems.

Multiplying Current Output D/A Converters
Analog Devices offers a wide range of high precision, multiplying current output (IOUT) D/A converters (DACs) that feature ±1 LSB INL and DNL specifications, from 12-bit up to an industry-leading 18-bit resolution. Our portfolio includes single and multiple D/A converters in small packages with parallel or serial SPI interfaces. Multiplying current output R-2R D/A converters allow for an external amplifier that’s optimized for specific applications and that does not require reference buffering, which enables high linearity. The SoftSpan™ feature allows software selectable output spans, therefore eliminating the need to add precision gain stages and the associated external jumpers, precision resistors, and amplifier circuitry. Integrated precision resistors allow for reference inversion, bipolar offset, and offset and gain adjustment.
