Ninox 640 II
VGA Resolution, Ultra Low Noise (18e-) , Cooled, Digital InGaAs Camera
The Ninox 640 II is the next generation of the highly successful Ninox 640. With an ultra low typical readout noise (rms) of 18 electrons and a typical dark current reading of <750e- at -15°C, the Ninox 640 II improves even further on it’s noise performance. The mechanical design of the camera is also much improved and the camera is significantly more compact than the initial Ninox 640. With dimensions of 87.30mm x 78.86mm x 79.30mm and weighing 550g, it is one of the most compact and lightweight scientific SWIR cameras available on the market.
The Ninox 640 II is a cooled, high sensitivity digital SWIR camera. Using a 640 x 512 InGaAs sensor, the Ninox 640 II enables high sensitivity imaging from 0.6µm to 1.7µm. The 15µm x 15µm pixel pitch enables a high-resolution SWIR image and with a typical readout noise (rms) of 18 electrons, the Ninox 640 II enables the highest SWIR detection limit.
SWIR for Non-Invasive Fluorescence Imaging of Small Animals
Non-invasive fluorescence imaging of small animals has been a technique widely used for years as a method in preclinical research. Techniques have developed considerably in recent years, but still face a number of limitations. Researchers detecting in the 500-900 nm range suffer from shallow imaging depth and high background due to light scattering and tissue autofluorescence.
Over the last five years there has been a growing interest in NIR-II/SWIR imaging detecting in the 1000-1700 nm range to greatly suppress these effects, affording single-cell resolution at ~ 3 mm depth and useful resolving power at up to ~ 1 cm depth. Raptor has worked closely with Nirmidas to develop the right camera choice for DeepVision, the Ninox 640-II… Continue reading the article

Raptor Photonics Ninox 640 SU
Raptor Photonics continues to push the boundaries in scientific SWIR imaging with the launch of the Ninox 640 SU, a vacuum cooled to -80°C InGaAs camera, offering ultra-low dark current for longer exposure times up to 5 minutes. Combining a low read noise of <40e- in high gain and a dark current reading of <300e/p/s at -80°C, the Ninox Ultra is one of the most sensitive SWIR cameras available on the market and perfect for imaging weak signals using longer exposure times. It offers a resolution of 640×512 and has a 15µm x 15µm pixel pitch.
The camera also offers a high intra-scene dynamic range of 56dB in high gain, enabling simultaneous capture of bright and dark portions of a scene. The Ninox 640 SU follows on from the launch of the Ninox 640 and Ninox 1280 cameras, which have attracted a lot of interest in applications including astronomy and in-vivo (NIR-II) imaging.
