QHYCCD QHY5III485C USB 3.0 Camera

QHYCCD is pleased to announce a new addition to its line of high speed, high QE, low noise, planetary cameras, the QHY5III485C.

The QHY5III485C uses Sony’s new IMX485, back-illuminated, 8.4 megapixel color CMOS sensor with an array of 3864 x 2176 pixels at 2.9um. With USB 3.0 interface, the full frame rate of 60 FPS at 12-bits or 90 FPS at 10-bits. Smaller regions of interest will yield even faster frame rates. This new

camera makes a great planetary combo with the other newly released QHY5III462C.

Large Sensor Size

The QHY5III485C has 4 times the area of the smaller QHY5III462C and 4 times the number of pixels. In area it is the same size as the popular IMX174 sensor but with back- illumination and higher resolution. The generous field of view provided by this larger sensor makes it ideal for solar

and lunar imaging whereas the smaller, faster QHY5III462C with its enhanced IR response is superior for imaging planets like Jupiter, Saturn and Mars.

High QE and sHCG

While the QHY5III485C does not have the extended near IR response of the QHY5III462C it does have sHGC (Super High Cain Conversion for exceptionally low (less than 1e-) read noise. For solar and lunar imaging, the NIR response is not required but the ability to take multiple short exposures in H-alpha light is ideal for solar use and making movies of solar prominences, arcs and eruptions.

Back Illumination

One benefit of the back-illuminated CMOS structure is improved full well capacity. In a typical front-illuminated sensor, photons from the target entering the photosensitive layer of the sensor must first pass through the metal wiring that is embedded just above the photosensitive layer. The wiring structure reflects some of the photons and reduces the efficiency of the sensor.

In the back- illuminated sensor the light is allowed to enter the photosensitive surface from the reverse side. In this case the sensor’s embedded wiring structure is below the photosensitive layer. As a result, more incoming photons strike the photosensitive layer and more electrons are generated and captured in the pixel well. This ratio of photon to electron production is called quantum efficiency. The higher the quantum efficiency the more efficient the sensor is at converting photons to electrons and hence the more sensitive the sensor is to capturing an image of something dim.

Allsky Application

The QHY5III485C standard package includes a 2.5mm Fisheye lens that converts the planetary camera into a high-resolution, 8.4 Megapixel All Sky camera with 180-degree field of view.
