Now shipping the LD250mTC5 LAB Series Laser Diode with Temperature Control Instrument.
With 250mA max to the laser diode, low noise, stable power and wavelength, the LD250mTC5 LAB touchscreen instrument enables advanced experiments that require consistent power, fewer fluctuations over time, and better stability.
The instrument provides an intuitive user interface and is compatible with most sensor types and all laser diode/photodiode combinations. The temperature controller provides 5A output with stability better than 0.0009°C and IntelliTune® PID temperature control. Laser cumulative current noise is 3 µA with a modulation input bandwidth of 450 kHz (CC mode). The thermoelectric cooler (TEC) and the laser are protected by features such as: current limits with Brick-Wall Never-Exceed circuitry; short-circuit disable; passive and active interlocks; load failure protection; over- and under-temperature limits on the load, and automatic laser shutdown upon TEC error.
Researchers from Germany have developed a high-speed pyroelectric receiver using a LiTaO3 pyroelectric detector as a cryogen-free solution for terahertz (THz) absorption spectroscopy measurements. This receiver can record spectra at frequencies up to 281 Hz without introducing artifacts into the observed spectral absorption profile. By operating at room temperature, the compact system provides a practical and efficient alternative to cryogenically cooled detectors, making it a reliable platform for THz spectroscopy, offering robust performance without the need for complex cooling infrastructure.
To optimize the performance and testing of the high-speed LiTaO3 pyroelectric receiver, researchers integrated the innovative capabilities of Wavelength Electronics’ QCL1000 OEM driver. Given the significant impact of temperature and noise on the pyroelectric receiver’s performance, ultra-low noise current drivers were required. Wavelength Electronics’ QCL1000 OEM driver operates with a low noise floor, maintaining an output current RMS noise of less than 0.7 μA at operating frequencies up to 100 kHz. This level of noise reduction is vital for accurately capturing the rapid spectral features without introducing artifacts, thereby ensuring a clean spectral absorption profile. This integration has proven instrumental in achieving high-speed data acquisition rates without compromising the integrity of the recorded spectra.
Thermistors are nonlinear, which means the relationship between resistance and temperature isn’t a straight line. That’s where the Steinhart-Hart equation comes in: 1/T = A + B(lnR) + C(lnR)^3.
This equation helps convert thermistor resistance into highly accurate temperature readings. It’s standard in scientific and industrial applications, and it’s easy to implement using online calculators.
A Note About Tariffs
Over the past few months, we’ve been keeping a close eye on the ripple effects of new international trade regulations. At first, the impact was minimal. But gradually, we began to see costs working their way through every part of the supply chain. We did what we always try to do: absorb as much as possible, look for efficiencies, and keep things running smoothly without passing the burden along.
As time went on, it became clear that some of these changes were going to stick around. Because of this, we’re introducing a tariff-related surcharge on certain orders, effective immediately. We know this isn’t welcome news, and it’s not a decision we made lightly.
We will keep you informed as changes continue to unfold.
We’re committed to being transparent, keeping you informed, and continuing to deliver the quality and service you count on, even as we adjust to a shifting global landscape.
We invite you to contribute topic suggestions, questions, and general feedback. Wavelength will incorporate as much reader input as possible.
