Hamamatsu Photonics has launched a pair of linear CMOS image sensors with long thin pixels to increase sensitivity in spectrometers, without hampering resolution. “The elongated vertical pixel enables efficient light collection, even with shorter integration times,” according to the company. “Surpassing conventional CMOS in the VUV [vacuum ultra-violet, see graph] region, both sensors exhibit remarkable sensitivity from 140 to 1,000nm.” ...

Spectrum Instrumentation has introduced a way to parallel its 12bit 10Gsample/s data acquisition cards up to eight channels, that can also produce 16 12bit channels at 5Gsample/s. Called Star-Hub, it works with the company’s recently introduced M5i.33xx series of PCIe digitisers. “The Star-Hub option is installed by mounting a single piggyback module onto any of the M5i series cards in ...

Danish company Vind-Vind is developing a turbulence model for the effect of wind on structures in complex environments. It will eventually include the atmosphere high above the volume of interest with wind gusts from different directions. As such, said Vind-Vind CEO Per Jørgensen, wind-tunnel measurements are not good enough and he needed real-world measurements throughout a large volume of atmosphere ...

Spectrum Instrumentation has added a GPU-based digital down-conversion (DDC) option to its PC-based ‘SCAPP’ software, used with its PCIe signal digitiser cards – effectively ADCs for PCs. Working with sufficiently-powerful Cuda-based GPUs, the DDC option allows on-the-fly baseband signal extraction, and is offered as an alternative to FPGA-based DDC and its associated programming. “The GPU, which can have thousands of ...

Thorlabs has announced a holographic grating spectrometer that spans 810 to 965 nm with sub-nanometre resolution. HG10 is fibre-based acquires at up to 130,000 scan/s, enabled by the USB 3.0 interface. External synchronisation is via a TTL-level trigger input. Inside, the spectrometer is based on the company’s Ganymede series of optical coherence tomography imagers. “The development of the HG10 was ...

German digitiser company Spectrum has introduced a dual-channel sampler board – an ADC board – that takes 12bit samples on both channels simultaneously at 3.2Gsample/s. Called M5i.3321-x16, it has 1GHz bandwidth front-end amplifiers with programmable full-scale ranges from ±200mV to ±2.5V, plus variable offset. Other models in the M5i family offer 2GHz bandwidth. The full input capacity can be streamed continuously ...

Spectrum Instrumentation has added driver support for the Nvidia Clara AGX computing architecture for AI medical instruments. This means that Spectrum’s digitiser boards (ADCs), arbitrary waveform generators (AWGs) and digital IO cards can be used with Clara AGX (right) for electronic signal acquisition and the generation of analogue and digital signals. “The Nvidia Clara AGX developer kit provides a platform ...

Anritsu has created the MS27201A remote spectrum monitor series, that includes a 43.5GHz version for new satellite downlink bands. A 110MHz measurement bandwidth supports common satellite downlink spans, DANL (displayed average noise level) is -164dBm and the typical TOI (third-order intercept point) is +20dBm. Other MS27201A versions work up to 9GHz or 20GHz. All work down to 9kHz. “Combining RF performance ...

Farnell is stocking spectrometer modules from Broadcom’s range. “Broadcom’s compact spectrometer modules are suitable for industrial sensing and mobile analytics in numerous applications,” according to Farnell. “Field and lab-based engineers can now access spectrometers from stock for same day shipping.” The USB-connected modules cover ultra-violet, visible and near-infra-red – alone or in various combinations. The parts Farnell is handling include: ...

Osram has created an ambient light sensor for mobiles and wearables that includes UV-A light detection. “While the UV-C portion of sunlight is blocked by the earth’s atmosphere, UV-A and UV-B radiation reaches the earth’s surface,” according to the company. “UV-B radiation penetrates only the upper layers of the skin and is responsible for sunburn. UV-A radiation, which accounts for ...
