Model QHY1253P (Four Direction Monochrome Polarize Version) COMS Sensor SONY IMX253 Global Shutter CMOS Sensor Pixel Size 3.45um*3.45um Effective Pixel Area 4032 (H) x 2998 (V) Effective Pixels 12 mega pixel Effective Image Area 13.91mm x 10.34mm Introduction QHY1253 has IMX253 Global shutter CMOS sensor with the special Polarize version. Monochrome and color version are also available. Compared with QHY550P, 1253P has a bigger sensor. It has important applications in gemstone, geology and material science, biology science. QHY1253 has build-in two stage TEC cooler. It can cooled the sensor to -35C below ambient and reduce the dark current, which greatly improving the dark signal detect performance. Especially for detect the tiny difference of the polarize light. This is necessary for the astronomy, life science and optical lab. Polarize Sensor With the on-pixel four direction polarize filter, A ploarize sensor can capture the polarize image at only one exposure. No need change the polarize filter for three times. Polarize detector can be used in industry image to detect the scratch, transmissible object and getting the no-reflection pictures. 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. Global Shutter Unlike the rolling shutter technology used in most CMOS cameras, a global shutter guarantees that the exposure time for the whole image area is uniform, beginning and ending at exactly the same time. This type of shutter is ideal for high precision applications. For high speed moving object and the atmospheric agitation the global shutter can generate undisborted imaging and realizes high picture quality.
