High QE Photocathodes Collect Almost All Incoming Electrons
The Hi-QE photocathode technology from Photonis provides a unique combination of extremely low dark counts, fast response time, and high quantum efficiency (QE).
These photocathodes lower dark counts as much as 10X, while boosting QE 50% over traditional S20 or S25 photocathode technologies. Hi-QE photocathodes are available in a variety of spectral detection ranges to fulfill specific application requirements: UV, blue, green and red.
The Hi-QE UV offers superior detection to 330 nm, while the Hi-QE blue provides improved response through 400 nm. The Hi-QE green option provides unparalleled response from 400-550 nm, while the new Hi-QE Red photocathode is optimized for the 400-900 nm spectral range, providing 50% greater quantum efficiency. At 650 nm, Hi-QE Red provides 22% QE – versus 16% in the standard S25 photocathode. Notably, at 900nm the Hi-QE red photocathode offers a 50% improvement over the traditional S25 photocathode.
Hi-QE photocathodes are available in these photon detectors:
