The BM-141GE (monochrome) 1.4 megapixel CCD camera
The BM-141GE (monochrome) is a 1.4 megapixel CCD camera suitable for a variety of machine vision applications, but is particularly well suited for outdoor applications, which are characterized by wide ranging and continuously changing lighting conditions.
With megapixel resolution, outstanding image quality, and a high level of automated operation, the BM-141GE provides a combination of high performance features well beyond that available from typical small format traffic and security cameras – both interlaced and progressive.
Excellent sensitivity and spectral response
The BM-141GE is designed around Sony’s popular ICX285 2/3” progressive scan CCD (1392 x 1040 pixels) providing excellent sensitivity and spectral response. This sensor uses its 6.45 µm pixel size and improved microlens technology to provide higher overall sensitivity (as low as 0.03 lux) with low smear characteristics. It also features extended spectral response in the near-IR region offering roughly 4X the sensitivity of conventional sensors at a 945 nm wavelength.
Low noise operation
Through a combination of sophisticated circuit design and thermal management techniques, the BM-141GE delivers a signal-to-noise ratio of greater than 58 dB, producing high quality images even in nighttime illuminated situations.
Full Auto Exposure function
The camera features an advanced Automatic Exposure Function that can simultaneously control gain, shutter, and lens iris to maintain optimum exposure levels across a wide range of changing lighting conditions as often occurs in outdoor surveillance/security and traffic applications.
