Stemmer Imaging announced that Toshiba has introduced two versatile 3-chip CMOS high-resolution cameras. The IK-HD5 is a progressive-scan full high-definition (HD) 1080p/1080i video camera featuring a removable optical low-pass filter for dual-mode imaging applications, according to the company. This allows the camera to be optimised for visible light or near-infrared (NIR) radiation. The IK-HD4 is an Ultra High Definition 3840 x 2160p, 50/59.94Hz camera system designed to provide sharp detail and rich colour in 4K resolution.
With up to 1000 TV lines resolution and a binning mode for a 4x increase in sensitivity, the IK-HD5 can be used for any HD video application, as well as NIR imaging for applications such as medical diagnostics using indocyanine green (ICG) and other fluorescing agents. Other applications include surgical microscopy, endoscopy, IR inspection and defence imaging systems. For enhanced NIR applications, the removable optical low-pass filter provides a switchable output between full-HD video in the visible and NIR wavelengths while the 3-chip CMOS sensor gives approximately 3 decibels (dB) increased sensitivity in the NIR, according to the company.
The compact IK-HD4 (110 millimetre [mm] × 40mm × 196mm) can be switched between 4K and 1080p/1080i resolution and offers up to 1600 TV lines resolution. It is suitable for applications where colour fidelity and resolution are critical, including broadcasting, clinical imaging and defence imaging. Both the IK-HD4 and IK-HD5 feature a C-mount lens mount and remote control via RS 232.
