High dynamic range and high sensitivity InGaAs 900-1700 nm cameras
New Imaging Technologies developes and manufactures InGaAs sensors and infrared (IR) cameras using the patented logarithmic response technology HDR that doesn't require TEC.
Addint a linear functioning mode HS (activates the TEC) the result is high sensitivity images.
Thanks to that, these SWIR cameras NIT-WiDy-SensS unbeatable high dynamic range: 120 dB and also high sensitivity
Thus you can see both very bright areas and very low illumination areas in the same image and at the same time.
They come with a 24-month warranty.
Key features of the NIT HDR InGaAs cameras (900-1700nm):
- 120dB dynamic range (logarithmic mode, HDR)
- 900 - 1700 nm
- TEC disabled in HDR mode and enabled in linear mode (HS: high sensitivity)
- Global shutter
- very low weight, size and consumption
- USB3.0, CameraLink, GigE, analog or SDI video interfaces
- resolution: 320x256px or 640x512; pixel pitch 15 um2
- "smart" versions with internal on-board processing (NUC, BPR & AGC)
- versions with Gated mode that allows taking images in a very short time period: 100ns - 9us
Typical applications of the infrared (NIR - SWIR) cameras with InGaAs sensors:
- Photovoltaics, solar and semiconductor field
- electroluminescence, photoluminescence
- Welding inspection
- Thermography
- Spectroscopy and microscopy, hyperspectral
-Inspection of electronic circuits and components
- IR imaging, specially low-light level and high speed
- NDT
- Laser beam profiling
- Laser science and medical imaging
- Drones, UAV, airborne: agriculture, mining, rescue,...
- Defense, security and surveillance, nicht vision
- Machine vision
- Additive manufacturing
