Tidas-E Base Series Photo Diode Array Spectrometer
WPIโs Tidas series is a high end fiber-optic spectrometer module designed for low noise applications. The Tidas series outperforms conventional bench-based spectrophotometers and CCD-based spectrometer modules, when it comes to high precision fiber optic sampling. It relies on a monolithic optical bench made by Zeiss, which is optimized for fiber optic applications. Most cuvette-based standard spectrometers lose more than 90% of light through expensive prism decoupling. The Tidas series is designed for fiber optic sampling cells. Using suitable light sources and sample cells, spectral detection in the wavelength range of 190 to 1100 nm can be performed at noise levels < 0.04 mAU peak to peak.

Dummy Load Resistor Kit
A365 can be used as a precise voltage source by placing a precision โdummyโ resistor load across the output terminals. Precision resistors (such as the 100 ฮฉ, 1000 ฮฉ and 10,000 ฮฉ resistors in WPIโs optional Dummy Load Resistor Kit #DRL) when placed across the output terminals convert the precision current levels to accurate voltage levels.
For example, 1 milliampere flowing through 1000 Ohms will produce 1 volt across the output terminal pair. Thus, models A365D and A365R can be used as low noise sources of accurate voltage pulses or DC. To maintain less than 1% error, avoid shunting the output dummy resistor with a load resistance less than 100 times the dummy resistance value.
