Photodiodes & IREDs for Smoke Detection

Product information "Photodiodes & IREDs for Smoke Detection"

Excelitas provides photodiodes and IREDs as well as custom assemblies with specified signal level range to address the requirements of electro-optical smoke detectors.

An electro-optical smoke detector consists of an infrared LED light emitting diode (IRED) and photodiode assembly which exhibits a signal under the presence of smoke in the detection volume (smoke chamber). Signal range under smoke and clean-air conditions and their long-term stability are key features of a smoke detector module.

Such an assembly can be an optical block containing an IRED and PD for (SMD) board soldering or the complete smoke chamber, which are produced in high volumes. In addition to the components presented in the tables above, Excelitas can provide higher value-add assemblies for smoke detection applications, including the following:

  • An optics block which consists in a Photodiode-IRED pair selected, assembled into a plastic housing and tested to have a controlled range of transfer function between the IRED to photodiode signal under given smoke conditions.
  • A smoke chamber with base which can be easily integrated on a PCB for use with the optics block.

For further details on these or other sub-assemblies, including readout ICs, please contact the AMS Technologies experts to discuss your requirements.

Application: Electro-optical Smoke Detection

Manufacturer "PCO Excelitas"
Excelitas PCO is a camera manufacturer leading in digital imaging innovation across various sectors, including scientific and industrial research, automotive testing, quality control, and metrology. Founded in 1987 as Pioneering in Cameras and Optoelectronics (PCO), the company initially focused on image-intensified cameras and later co-invented the sCMOS sensor technology, elevating imaging performance standards. PCO was acquired by Excelitas in 2021. The camera portfolio of Excelitas PCO ranges from deep ultraviolet (DUV) to shortwave infrared (SWIR), encompassing long exposure to high-speed and line scan to high-resolution area scan capabilities. The company's software suite supports control and processing across a wide range of platforms and architectures. https://www.excelitas.com/product-category/pco Countries of Representation Denmark, Finland, Iceland, Norway, Sweden
