Powerful Infrared Sensitivity For Faint Samples
The NIRvana® 640 offers incredible sensitivity with greater than >85% Quantum Efficiency between 950 nm and 1500 nm, ensuring you collect every photon you can.
The biggest barrier to low light SWIR imaging is dark current. The NIRvana® 640 offers incredible low dark current – only 40e-/p/s, enabling longer exposures for faint samples.

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® 640 can sustain its -85C sensor temperature over many hours. Combined with our lifetime guaranteed, zero maintenance vacuum, our cooling technology provides the reliability to keep your experiments running.

Minimise Scene Noise
SWIR photons are everywhere. A significant source of unwanted noise in SWIR imaging is infrared photons from around the sample. The NIRvana® 640 features a proprietary cold shield, which blocks photons you don’t want, improving image quality.

Large Pixel Size Delivers High Sensitivity
We don’t just have lower noise – we collect more photons too. With larger pixel area comes greater light detection ability. The 20 μm pixels of the NIRvana® family collect 80% more light than 15 μm pixel cameras, and 4 times as much light as 10 μm pixel cameras.
