oriba Scientific, the Raman and fluorescence spectroscopy systems
specialist, has just debuted its new Syncerity 1024 x 256 CCD Detector for UV-VIS-NIR. Tis new, open- electrode -60°C TE-cooled CCD detector offers the lowest noise and highest dynamic range in its class.
Te company addressed the need for improved performance from CCDs available for OEM. Te Syncerity is a research grade spectroscopy camera that combines affordability, performance and versatility for OEM, as well as research applications. Its flexible design and software allows Horiba’s OEM dedicated team to easily customise this camera platform for industrial requirements, ranging from alternate CCD chips to electronics customisations. Ruggedised connectors ensure overall system integrity in industrial environments, and it’s all metal sealed technology
provides a permanent vacuum which comes with a lifetime maintenance free warranty.”
OEM integration Te Syncerity’s ultra compact size is designed for compatibility with microscopes and OEM integration. According to Horiba, at its slow scan speed of 45kHz, this detector offers unmatched dynamic range (92.5dB in image mode) and has the lowest readout noise and non-linearity (< 0.4 per cent) in its cooling class. In addition, its open electrode CCD technology offers broad spectral coverage with QE of 33 per cent at 250nm and 50 per cent at 800nm, and provides a lower-cost alternative to eliminating the ill effects of etaloning in the near IR region, which traditionally required the use of expensive deep depletion CCD sensors.
“Te Syncerity CCD Detector is the perfect choice for low light level
detection in a variety of spectroscopic applications where ultimate deep cooling is unnecessary,” said Michael Narozniak, director of multi-channel detectors for Horiba Scientific. “Tis new detector complements our other lines of deep cooled, high performing spectroscopic CCD cameras, which include the LN2 cooled Symphony and TE cooled Synapse (-80 to -100°C) solutions. Now price and performance don’t have to be exclusive from one another, especially in applications and markets that are price sensitive.”
Rapid data collection In another innovation, Horiba has launched the Dual-FL which combines a spectrofluorometer and spectrophotometer for the simultaneous rapid collection of fluorescence and absorbance data.
