It is well suited for ultra-low light detection, high dynamic range and high speed imaging applications, providing solutions for machine vision, life science, astronomy, etc.

 

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.

 

Dhyana 4000A

To meet the challenges of ultra-low light detection, high dynamic range and high speed imaging applications, Tucsen has released the newest Scientific CMOS_(sCMOS) camera: Dhyana 400A, which represents the most advanced imaging technology in the world. Compared to the traditional cooled CCDs, The Dhyana 400A has advantages of lower noise, higher sensitivity, wider dynamic range, faster read speed and so on, as shown in the table below. The Dhyana 400A is ideally suited for life science, physics, astronomy, etc, where ultra high performance is required. The release of Dhyana 400A brings a new breakthrough in the field of digital imaging.
 
Low Read Noise
Though with superb large pixel size 11µm×11µm, the Dhyana 400A only has incredibly low 1.5e read noise.When the unit area of each pixel is taken into account, the Dhyana 400A has lower noise than all the CCD and sCMOS cameras available in the market. The Dhyana 400A offers truly extraordinary read noise.
 
High Signal-to-Noise Ratio
The Dhyana 400A shows dramatically higher SNR performance over cooled CCDs regardless of incident photons. Once the incident photons exceed 8,the SNR of Dhyana 400A also outperforms EMCCDs.
 
Ultra-high Sensitivity
The absolute response threshold of Dhyana 400A is as low as 3 photons, which guarantees the trace detection.
