InGaAs Camera
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.
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.
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.
