Applications where ORCA-Flash4.0 LT shines
Multi-dimensional imaging
Collect large data sets from x, y or z with multiple wavelengths more efficiently. The combined features of large field of view, low light performance and speed means less time at the scope and more time finding the answers.
3D imaging
Multi-wavelength Z-series with resulting 3D reconstruction.
Ca2+ imaging
Ca2+ imaging using W-VIEW Mode (Independent exposure time setting)
Performance beyond interline CCD
Excellent image quality
The combination of high quantum efficiency and low noise allows the ORCA-Flash4.0 LT to produce images that are both visually pleasing and quantitatively relevant. The ORCA-Flash4.0 LT exceeds the SNR performance of Gen I sCMOS at all input photon levels and that of interline CCDs at less than 5000 photons per pixel. This means reduced exposure times that maintain strong SNRs across a broad range of sample intensities while at the same time providing large field of view and better temporal resolution as compared to CCDs.
Large field of view
The ORCA-Flash4.0 LT provides 3× larger field of view compared to commonly used interline CCDs (e.g., ICX285) and is ideally suited to utilize the entire field of view of research microscopes.
Fast speed
The ORCA-Flash4.0 LT provides 2× frame rate at full resolution as compared to interline CCDs enabling high-speed image acquisition with large field of view.
W-VIEW Mode
In addition to the intrinsic quality of the sensor, WVIEW Mode is newly implemented as one of the key features. This function is optimized for simultaneous image acquisition of dual wavelength images with our Image splitting Optics "W-VIEW GEMINI" and expands the possibilities of low light imaging applications.
• Independent Exposure Times
For two halves of the sensor, the different exposure time can be set independently by software.
• Independent and Selectable Readout Directions
W-VIEW Mode enables multiple scanning directions under favor of rolling shutter mechanism. Scanning options for both sides of sensor can be set separately. When combining W-VIEW GEMINI, it enables the user to acquire sophisticated dual wavelength images simultaneously which are synchronized the readout with the scanning light source.
• Independent Subarray
Each ROI on top and bottom halves of the sensor is configurable. Data reduction and faster frame rate are feasible due to appropriate ROI setting.
Configuration

PC requirements
With the introduction of the ORCA-Flash4.0, users are now able to stream 4 megapixel images to their computers 100 frames per second. The computer requirements for this high data rate can be met by using the guidelines listed this PC Recommendations for ORCA-Flash4.0.
