The world's only 90% QE scientific CMOS sensor
This increase in quantum efficiency over existing sensors further improves the absolute response threshold of Dhyana 90 to 1.6 photons, making it the most sensitive sCMOS cameras in the world. The Dhyana 90 has a powerful capacity for photon counting.
|
1.3e- Low Read Noise
With superb large pixel size 11µm×11µm, the Dhyana 90 exhibits 1.3e- read noise. Regarding the read noise per unit area of each pixel, the Dhyana 90 has the lowest noise of all the CCD and sCMOS cameras in the market. The Dhyana 90 offers truly extraordinary signal-to-noise ratio.
 |
100,000e¯ Full Well Capacity, High Dynamic Range
93 dB dynamic range and 16 bit digital output, enables ultra-low signals and strong signals to be captured simultaneously.
 |
| |
-25° Cooling, Low Dark Current
Through thermoelectric cooling, the dark current of Dhyana 90 at -25℃ is lower than 0.15e-/pixel/s. By the high vacuum sealing design, a lower and more stable cooled temperature is achieved.
 |
Back-illuminated chip technology
Tucsen uses the world's leading back illuminated sCMOS technology, which, when compared with the traditional sCMOS technology, greatly improves the light capture efficiency.
