4.2 Megapixel Scientific CMOS Camera
4.2 Megapixel Scientific CMOS Camera Photometrics Prime is the first intelligent scientific CMOS (sCMOS) camera to incorporate a powerful FPGA-based Embedded Signal Processing™ engine (ESP). ESP enables advanced real-time processing features: |
|
- PrimeEnhance™ quantitatively increases the Signal to Noise Ratio by 3X-5X, increasing the clarity and quality of images. -PrimeLocate™ dynamically evaluates acquired images and reduces the surplus of data generated during high speed super-resolution imaging. |
|
- Increase SNR 3x to 5x at low light levels by reducing photon shot-noise | |
- Preserve signal intensities ensuring quantitative measure-ments | |
- Extend cell lifetimes with reduced phototoxicity and photobleaching | |
- Extremely useful for low light imaging applications dominated by noise | |
Multi-ROI | |
The surplus of data generated by sCMOS devices – 800MB per second – is challenging to acquire, analyze, and store, requiring special interfaces and expensive SSDs. While a large Field of View (FOV) is convenient for imaging, at times, only certain areas contain the desired information. | |
Multi-ROI allows users to select up to 15 unique ROIs within the FOV, and only these selected regions are transferred to the host computer. This allows for a large reduction in the amount of data acquired but ensures that the critical information is obtained. | |
