High-Performance Photodetectors for Advanced Microscopy
High-Performance Photodetectors Powering the Next Generation of Advanced Microscopy
As scientific imaging and microscopy continue to evolve, the demand for highly sensitive and precise detectors has never been greater. Opto Diode’s AXUV series photodetectors are specifically designed to meet the needs of cutting-edge research in electron microscopy, synchrotron instrumentation, and materials analysis
Engineered for Accuracy and Reliability
The AXUV series photodiodes deliver superior linearity, low dark current, and high sensitivity across a broad spectral range—from soft X-rays to vacuum ultraviolet (VUV) wavelengths (5–200 nm). These characteristics enable accurate signal capture even under high-energy or vacuum conditions.
In electron microscopy (SEM and TEM), AXUV detectors are used for backscatter electron detection and beam alignment, ensuring precise image contrast and measurement accuracy. Their thin entrance windows and fully depleted silicon design allow for efficient charge collection with minimal signal loss—critical for advanced imaging and surface characterization.
Built for Harsh Environments
Each detector in the AXUV series is designed to perform reliably in high-vacuum and high-energy environments, making them ideal for demanding scientific and industrial setups. Models are available in compact, windowless packaging to maximize transmission and integration flexibility across various microscopy platforms.
Opto Diode’s detectors are manufactured and tested in the USA to ensure consistent quality and long-term stability, even under challenging conditions.
Customizable Solutions for Specialized Research
In addition to standard configurations, Opto Diode offers customizable detector layouts, including segmented designs for spatial sensitivity, circular apertures, and specialized packaging options. These tailored solutions support integration into electron spectrometers, synchrotron beamlines, and vacuum instrumentation, allowing researchers to optimize detector performance for their specific experimental needs.
