Applications
Thin-film metrology: nanometer-scale semiconductor films produce fine, potentially weak interference signals easily buried in noise, requiring sensitivity to small signals. Consumer electronics: display luminance and chromaticity testing requires high sensitivity and dynamic range across low to high brightness. Agriculture and environment: weak solar-induced chlorophyll fluorescence (SIF) requires sufficiently high spectral resolution. Life sciences: weak Raman signals from biological samples such as drug ingredients and tumor cells require sensitive cooled detectors to reduce noise and improve signal strength.
Key Features
Peak quantum efficiency. Peak quantum efficiency >90%. A Hamamatsu cooled back-illuminated area-array detector uses TEC cooling to -15℃ at room ambient temperature, with a maximum integration time of 60min, significantly improving dark-current suppression and spectral response intensity. Peak quantum efficiency exceeds 90%@600nm. Ultrahigh dynamic range. 85,000:1 ultrahigh dynamic range. Based on ExtremeDR™ technology and a new-generation electronic platform, comprehensive optimization of signal acquisition and processing provides a dynamic range up to 85,000:1, greatly improving spectral signal quality and detection system confidence. Replaceable slit: the upgraded optical platform supports user replacement of 5~200μm slits and wavelength accuracy calibration. SMA, FC/PC and other incident-light interfaces can also be customized for different applications. Typical stray light. Typical stray light 0.1%. Based on StrayAbs™ technology, an upgraded optical platform and innovative materials significantly suppress stray light. In the full-band (200~980nm) configuration, typical stray light is as low as 0.1%. Dual RoHS and EMC compliance. Dual EU RoHS and EMC certification. Full-process control from raw materials through production ensures freedom from heavy-metal contamination and compliance with EU RoHS certification standards and EU market access requirements. The equipment also operates stably in complex electromagnetic environments without interfering with other equipment and has international EMC certification, supporting high compatibility and low failure rates.
