Optical Sensors & Detector – Transducer for Photodiodes
Mounted Photodiode
Mounted Photodiode Assembly for Precision UV Detection, Stable Performance, and Easy System Integration in Industrial Applications
The Mounted Photodiode from SGLUX is a pre-assembled, high-stability UV detector module designed for direct integration into measurement and monitoring systems.
Built around a precision SiC, GaP, or Si UV photodiode, it is mechanically mounted in a rugged, light-tight housing that provides electrical shielding, optical alignment, and environmental protection.
Each detector is pre-wired with standard connectors, simplifying connection to AMPCON, SGCD4, or TW-MF2CAB amplifier boards.
Available in several spectral variants — UVC (200–280 nm), UVB (280–315 nm), and UVA (315–400 nm) — these modules deliver accurate, drift-free responsivity under laboratory or outdoor conditions.
With temperature-resistant encapsulation, EMI-shielded cabling, and NIST/PTB-traceable calibration, the Mounted Photodiode ensures repeatable and reliable UV measurements for scientific, industrial, and environmental applications.
Understanding Mounted Photodiode
The Mounted Photodiode converts ultraviolet radiation into measurable electrical current, providing a calibrated, ready-to-install sensing solution.
Its pre-mounted design eliminates the need for complex alignment or soldering, ensuring stable optical geometry and low signal noise.
The detector’s sealed metal housing minimises contamination and mechanical stress, maintaining constant responsivity even under extended UV exposure.
Each model is factory-calibrated and optimised for spectral purity, guaranteeing precise response in UVA, UVB, or UVC bands.
This plug-and-play configuration simplifies integration with signal conditioners, amplifiers, and digital boards, making it ideal for calibration setups, process control, and portable radiometers.
