Sensors and detectors sCMOS sensor has 30,000:1 dynamic range


Andor Technology has announced several performance enhancements to its Neo camera, based on next-generation scientific CMOS (sCMOS) technology.


The enhancements include faster sustained frame rates, better image quality, hardware pixel binning, flexible region of interest capability with single pixel granularity, an accurate timestamp and improved global snapshot exposure performance. Neo’s 5.5 Megapixel sCMOS sensor, with 6.5µm pixel size, achieves a 1 electron read noise at 30fps. Its dual amplifier architecture facilitates a wide dynamic range of 30,000:1. Neo delivers deep vacuum cooling down to -40°C, which is critical to maintaining the low noise advantage and a minimal pixel blemish specification across all exposure conditions.


The camera offers comprehensive FPGA intelligence for superior image quality and quantitative stability. Coupled with a 4GB on-head image memory, it has the ability to acquire extended kinetic bursts at frame rates that are faster than variable hard drive write speeds. This therefore overcomes the need for expensive and complex PC solutions. www.andor.com


Radiometer offers USB enabled remote control


Gooch & Housego has announced the release of the OL 730E radiometer, photometer. This newest model in the OL Series 730 line boasts a smaller footprint and reduced cost while providing similar research-grade precision and accuracy. The OL 730E has an internal preamplifier and a sensitivity of 1 x

Single photon counting becomes more accurate


Aurea Technology is launching its newly-designed SPD_AT, an all-in-one high-performance near infrared time-resolved single photon counting module for Time Correlated Single Photon Counting (TCSPC) applications. The SPD_AT is an ultra-low-noise, high quantum efficiency and low timing jitter near infrared (900-1700nm) single photon counter with 50ps timing correlation feature. The SPD_AT includes a Geiger-mode InGaAs avalanche photodiode and thermoelectric coolers that


Multiple functions possible with high sensitivity thermal detector


Ophir Photonics has announced its BeamTrack 3A-Quad, a high sensitivity thermal detector that combines multiple functions, power, energy and position in a single, compact sensor. The 3A-Quad accurately measures power from 100µW to 3W and energy from 20µJ to 2J. In addition, the sensor tracks beam position down to 0.1mm. This provides increased


ensure detection efficiency up to 25 per cent, a very low dark count rate <5.10-6


per ns gate, and


a low timing jitter of <180ps. The SPD_AT is supplied with an easy-to-use and ergonomic GUI compatible with LabView and C++.


A dual version, the SDP_AT_M2, with two photon detectors is also available. The SPD_AT time-resolved single photon counter family is suitable for use in fluorescence lifetime, photoluminescence, spectroscopy and time correlated single photon counting applications. www.aureatechnology.com


measurement accuracy for high sensitivity applications where it can be difficult to centre laser beams on sensors with small apertures and recessed surfaces.


The 3A-Quad has a small 9.5mm aperture and measures a broad spectral range from 190nm to 20µm. The integrated beam position measurement function also allows tracking of beam wander. www.ophiropt.com

amperes. It can be virtually controlled via the USB interface, and claims a response time as fast as 0.1 seconds and a full-scale range of 2 x 10-10


to 2 x 10-3 amperes. Also being


offered with the radiometer will be a series of TE-cooled detectors, which will provide enhanced temperature stability over time while utilising a smaller control unit. www.goochandhousego.com
