PRODUCT UPDATE
SENSORS & DETECTORS
C12494-222S mid-infrared detector module Hamamatsu Photonics has released the C12494- 222S InAsSb mid-infrared detector module. The module features two-stage thermoelectric cooling and built-in amplification to offer high signal-to- noise ratio in a compact package. It is also RoHS- compliant, ensuring both safety and environmental friendliness. The detector is easy to use – it just needs to be connected to a DC power supply and is ideal for integration into portable instruments for gas sensing, remote temperature measurement or mid- infrared spectroscopy.

NTCWS temperature sensors
TDK has introduced its new NTCWS series of temperature sensors. These bondable NTC thermistors can be mounted with Au wire bonding inside the package for highly accurate temperature detection of laser diodes used for optical communication. The NTCWS series supports a narrow
tolerance (±1%) of resistance and B value and can be mounted with Au wire bonding near the laser diode for highly accurate temperature sensing. The thermistors can withstand operating temperatures of -40 to 125°C. Since the wavelength of laser diodes changes with temperature, controlling the temperature is the key to improving their performance.

DesignCore RS-L1432U mmWave radar sensor
D3 Engineering has released the DesignCore RS-L1432U mmWave radar sensor. The sensor caters to low-power and cost-effective automotive applications, such as park assist, kick-to-open, and collision avoidance, and industrial applications such as level sensing. The RS-L1432U, built upon semiconductor
manufacturer Texas Instruments’ AWRL1432 device, offers versatile mmWave radar algorithms for measurement, detection, and tracking. It offers a one-inch cube shape with a heat-spreading metal body and mounting tabs. The sensor is suitable for PC, embedded, or
standalone applications, aiding field testing, algorithm development and demonstrations. The sensor covers the 76-81GHz band, with 11dBm transmit power and 12.5dB noise figure. Its main interface is a USB-C connector, delivering power and radar data, and it is pre-programmed with Texas Instruments’ SDK firmware.

FiberEdge GN1816 amplifier and GN1848 laser driver
TAC-440 MEMS Inertial Measurement Unit Emcore has released the TAC-440 MEMS Inertial Measurement Unit (IMU), offered in a compact package of less than 5 cubic inches. The TAC-440 IMU is based on Emcore’s quartz MEMS inertial sensor technology, which enables repeatable, high-volume production of machined sensor structures combined with the large signal output and thermal stability of quartz materials. It features 1°/hour gyro bias and 1mg accelerometer bias stability with very low 0.05°/√hour Angle Random Walk (ARW) over a wide temperature range.
The TAC-440 IMU is designed for demanding, mission-critical, rugged environments in a wide variety of defence, commercial, industrial, and marine applications. It features continuous Built-in

Test (BIT), configurable communications protocols, and electromagnetic interference protection. The TAC-440 supports four data message synchronisation methods with either input synchronisation pulse capability or an output time of validity capability. Users can choose whether the synchronisation pulse is internally generated and output as a time of validity of the output data or whether the TAC-440 software will identify the synchronisation pulse input and synchronise the output data to the input pulse.

Semiconductor manufacturer Semtech has added the FiberEdge GN1816 and GN1848 chipset to its portfolio of PAM4 transimpedance amplifiers and linear laser drivers. The GN1816 is a 56GBd feature-rich quad 250µm-pitch low-power, low- noise, and high-gain transimpedance amplifier, while the GN1848 is a 56GBd quad low-power, highly linear vertical-cavity surface-emitting laser driver. Both chips are available as wire-bondable
bare dies and are designed for 400GBASE- SR4/VR4 and 800GBASE-SR8/VR8 PAM4 multi-mode optical transceivers and AOCs. They are designed for high-speed, short-reach interconnects, enabling re-timed linear drive and active optical cable applications.

LASERS & DIODES
3kW single-mode AMB laser IPG Photonics has expanded its range of dual-beam fibre lasers to include a new Adjustable Mode Beam (AMB) laser source capable of delivering a 3kW single-mode laser beam in the core. An industry first, according to IPG, this increase in single- mode power offers exceptional speed and productivity improvements to deliver spatter-free battery welding speeds up to 2X faster than possible with lower core powers. Battery manufacturers often prefer single- mode fibre lasers for precision welding applications due to their ability to focus their power into extremely small spot sizes on the part. IPG’s AMB dual-beam lasers utilise a secondary ring beam that works in tandem with the single-mode core to stabilise the weld pool, virtually eliminating weld defects such as spatter, cracking, and porosity. The lasers can be configured with a wide range of beam parameters to offer optimised performance in a variety of welding applications.
