NIRvana® HS
SWIR For Science
The NIRvana® HS InGaAs focal plane array (FPA) SWIR camera is your versatile scientific imaging solution, delivering both high speed imaging and up to 60+ second exposure times.
900 – 1700nm SWIR / NIR-II
Low Dark Current (<500e-)
Image Quality Optimised
250fps at Full 640×512 Resolution
Deep Cooling That Lasts
Weak signals require a long exposure time to integrate. The primary challenge to low light imaging for SWIR cameras is exposure-time-dependent dark current noise. This can be reduced with camera cooling. However, some cameras on the market can only sustain their advertised cooling temperatures for a few minutes.
Though our industry-leading cooling and hermetic seal vacuum technology, the NIRvana® HS can sustain its -55°C sensor temperature over many hours. Combined with our lifetime guaranteed, zero maintenance vacuum, our cooling technology provides the reliability to keep your experiments running.
Excellent Temporal Resolution
Capture high-speed events with incredible detail thanks to the 250fps full sensor frame rate, and 2 microsecond minimum exposure time. Combined with ultra-high precision hardware triggering, the NIRvana® HS is an excellent choice for semiconductor and photovoltaic failure analysis, and other high-speed applications.
Higher Image Quality InGaAs
Achieving the high image quality that scientific applications demand has historically been a challenge for InGaAs sensor technology. With the NIRvana® HS, non-uniformity corrections and advanced pixel correction algorithms provide unparalleled image quality out of the box.
Minimize Scene Noise
SWIR photons are everywhere. A significant source of unwanted noise in SWIR imaging is infrared photons from around the sample. The NIRvana HS features a proprietary cold shield, which blocks photons you don’t want, improving image quality.
