Features
• Ambient temperature operation
• No bias required
• Short time constant
• No flicker noise
• Operation from DC to VHF
• Perfect match to fast electronics
• Wide dynamic range
• Low cost
• Custom design upon request
The PVI-λopt photodetectors series (λopt - optimal wavelength in micrometers) feature
IR photovoltaic detector, optically immersed to high refractive index GaAs
hyperhemispherical (standard) or hemispherical or any intermediate lens (as option)
for different acceptance angle and saturation level.
This series is easy to use, no cooling or heatsink needed. The devices are optimized
for the maximum performance at λopt. Cut-on wavelength can be optimized upon
request. Reverse bias may significantly increase speed of response and dynamic
range. It results also in improved performance at high frequencies, but 1/f noise that
appears in biased devices may reduce performance at low frequencies.Highest
performance and stability are achieved by application of variable gap HgCdTe
semiconductor, optimized doping and sophisticated surface processing.
Standard detectors are available in TO39 or BNC packages without windows. Various
windows, other packages and connectors are available upon request.
