This series of 5MPix cameras is based on IMX264, IMX250 and IMX250MZR image sensors from Sony’s Pregius Gen2 line of CMOS Sensors. These image sensors combine high sensitivity and a low read noise and are therefore a great choice for imaging under a wide range of conditions, including low-light imaging applications such as fluorescence microscopy. Sony’s Global Shutter technology ensures that all pixels begin and end exposure simultaneously. This is particularly useful in imaging conditions in which the field of view changes rapidly, either due to fast motion or due to rapid changes in light intensity.
The -POL version of this camera utilizes the IMX250MZR imager which leverages Sony’s Polarsens technology. A repeating quad (2×2) array of wire grid polarizers is fabricated directly onto the image sensor, between the microlens array and the pixel array. It is conceptually similar to the color filter array in a Bayer filter, except that instead of the deposition of color-dots, wire grid polarizers are fabricated on each pixel. As shown in the sketch below, for each pixel there is one of four linear polarizers with orientations of -45°, 0°, 45°, or 90° introduced between the microlens and the light-sensitive photodiode. The pixels are therefore responding to the linear polarization states of the incident light. Integrating the polarizers between the microlenses and photodiodes minimizes crosstalk and increases the alignment accuracy between the polarizer orientations and their respective pixels compared to a polarizer array placed in front of the microlens array. The resulting pixel values may be used used via software to compute information about the direction and degree of polarization in the Field of View.
All cameras in this series are bundled with Pixelink Capture, a free, real-time, interactive multi-camera software application.
