QHY550P Four Direction Monochrome Polarize CMOS IMAGER

QHY550 has the 2/3inch SONY 5.0mega pixel IMX250 Global shutter CMOS sensor. Besides the monochrome and color version it has the special Polarize version.

Unlike the rolling shutter technology used in most cmos cameras, The Pregius is global shutter pixel technology for active pixel-type CMOS image sensors that use Sony’s low-noise CCD structure,and realizes high picture quality. For high speed moving object and the atmospheric agitation the pregius sensor can generate undisborted imaging.

QHY550 has build-in two stage TEC cooler. It can cooled the sensor to -35C below ambient.  This can reduce the dark current of IMX250 significantly. Which greatly improving the dark signal detect performance. Especially for detect the tiny difference of the polarize light. Which is necessary for the astronomy, life science and optical lab.

With  the on-pixel four direction polarize filter, It can capture the polarize image at only one exposure.No need change the polarize filter for three times.  Tt can generate the polarize video at 68FPS high frame rate. Polarize detector can be used in industry image to detect the scratch, transmissible object and getting the no-reflection pictures. In gemstone,geology  and material science, biology science it also has important applications.

Since the polarizer is formed during the semiconductor process, form and formulation of polarizer, uniformity, mass productivity and durability are excellent compared to conventional polarization sensors. Furthermore, The Polarization sensor is covered with an anti-reflection layer which helps to reduce reflectance and avoids poor flare and ghost characteristics.
