QHY550 Cooled CMOS Camera
World First Cooled Polarize Camera | Pixel Class Polarize Filter Four Directions
4 Direction | wire-grid polarizers Semiconductor process
Low Dark Current | 2-stage TEC cooled Temperature Regulated
Global Shutter | High Speed Capture Undistorted Imaging
High Frame Rate | USB3.0 Interface 67FPS @ 5.0mp
DSO/Comet Polarize Imaging
Many deep sky object like the nebula etc has polarized light emitted. By using the QHY550P cooled polarize camera you can get an new looking at these object.
Solar Polarize Imaging
There is a lot of solar phenomenon has polarize information, like the corona and the structure of sunspot.
Industy,Gemstone and Biology Imaging
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.
