Excelitas Introduces SPCM-1064 Single-Photon Counting Module with Superior Photon Detection Efficiency at 1064 nm

Excelitas^®, a leading provider of advanced, life-enriching technologies that make a difference, serving global market leaders in the life sciences, advanced industrial, next-generation semiconductor and avionics sectors, announced the SPCM-1064. Engineered for high-performance detection across the 905 nm to 1064 nm wavelength range, the new single-photon counting module delivers superior near-infrared (NIR) sensitivity where many analytical and quantum optical systems operate.

At the core of the SPCM-1064 is a high-efficiency silicon avalanche photodiode that provides typical single-photon detection efficiency (PDE) of 10% at 1064 nm – a wavelength where reliable photon counting has traditionally been difficult. The module also delivers greater than 50% PDE from 750 nm to 950 nm, offering excellent uniformity across a large 500 µm active area for more consistent signal capture and reduced calibration for precise measurements. SPCM-1064 preserves the proven strengths of Excelitas’ established SPCM-AQRH product family with enhanced NIR and 1064 nm response capabilities.

“The SPCM-1064 extends single-photon counting into the challenging 1064 nm region with a level of sensitivity and stability not previously available,” said Richard Simons, Program Director for Photon Detection at Excelitas. “This enables researchers and system developers to achieve clean, low-noise detection in applications such as Raman spectroscopy, IR photoluminescence and quantum-optics experiments, particularly where weak signals or fluorescence would overwhelm standard detectors.”

Key Product Features:

• High PDE across key NIR wavelengths:
• • Typical 57% PDE at 830 nm: Strong sensitivity for Raman setups, fluorescence-suppressed spectroscopy and TRPL using 830 nm excitation.
  • Typical 58% PDE at 905 nm: High efficiency in NIR analytical systems, nonlinear optics experiments and 905 nm-based excitation schemes.
  • Typical 10% PDE at 1064 nm: Cutting-edge detection capability at the challenging 1064 nm wavelength, supporting Raman spectroscopy, IR photoluminescence, wind lidar, aerosol monitoring and quantum optics experiments
• Large 500 µm active area: Improves photon collection from divergent beams, reduces alignment sensitivity and ensures stable coupling efficiency in microscopy and spectroscopy.
• High linearity at high count rates: Maintains accurate quantitative measurements critical for fast scans and dynamic experiments, even in high-flux conditions.
• Gated output option: Enables precise timing control and background suppression for improved signal-to-noise performance.
• Single +5 V power supply: Simplifies system integration and reduces power-supply complexity.

Excelitas will showcase the SPCM-1064 Single Photon Counting Module January 20 – 22, 2026 at SPIE Photonics West 2026 in San Francisco, CA in Booth #637. For additional information, visit: https://www.excelitas.com/product-category/single-photon-counting-modules.
