Excelitas Technologies Introduces NIR-Optimized Single Photon Counting Module
Enhanced Device Provides High Detector Efficiency to Support Many Applications, Including Long-Range LIDAR, Quantum
Communications and Microscopy
WALTHAM, Mass., January 17, 2017 – Excelitas Technologies®, a global technology leader delivering innovative, customized
photonic solutions, introduces SPCM-NIR, a Single Photon Counting Module specifically selected and performance-optimized for the near-infrared (NIR) wavelength spectrum. This
NIR-spectrum enhanced device is designed to support long-range LIDAR, quantum communication and microscopy applications, as well as many others.
The Excelitas SPCM-NIR achieves enhanced red and NIR sensitivity while maintaining other performance parameters of Excelitas’ standard SPCM-AQRH, such as outstanding uniformity, overload protection,
temperature stability and linearity. It uses a specially selected silicon avalanche photodiode (SLiK) with peak single photon detection efficiency (PDE) at
780nm, typically better than 73%, while maintaining uniformity over a 180 μm diameter active area. The SPCM-NIR features gated output and a single 5V power
supply and offers linearity over a high count rate.
Bernicy Fong, Product Specialist comments, “The Excelitas SPCM-NIR provides exceptional capabilities for a wide range of exciting, cutting-edge
applications. As a technology leader in the industry, we are pleased to offer high NIR single photon detection efficiency to our customers to best meet their
Additional applications for the SPCM-NIR include photon correlation spectroscopy, astronomical observation, adaptive optics, optical range finding, particle
sizing, ultra-sensitive fluorescence, and imaging.
With the SPCM-NIR, a maximum count rate can be sustained if the case temperature is maintained within specified limits. Its peak light intensity is 104
photons per pulse, with pulse width < 1 ns. Each module is supplied with test data indicating the module’s actual dark count, dead time, pulse width, photon
detection efficiency and linearity correction factor.
Excelitas’ series of photon counting modules are designed and built to be fully compliant with the European Union Directive 2011/65/EU – Restriction of
Hazardous Substances in Electrical and Electronic equipment (RoHS).
