QHY CCD QHY5III678M

QHY5III678M is a new planetary and guiding camera
of the 2nd generation of QHY5III series, the upgraded version of
QHY5III178M, with excellent near-infrared high sensitivity as seen below.

In
this latest generation of sensors, the photo-diode portion of the pixel
well is physically deeper than in previous sensors, allowing photons of
longer wavelengths to penetrate deeper into the substrate. This
dramatically increases the sensor’s sensitivity to red and near-infrared
(NIR) light. The sensor displays almost equal peak sensitivity to NIR
light as it does to light in the visible spectrum.
