The ORCA-Flash4.0 LT makes it easy to be brilliant. With 2× the speed, 3× the field of view and up to 5× the signal to noise over even the best interline CCD cameras, the ORCA-Flash4.0 LT brings high end performance to every imaging project. From brightfield to fluorescence, from live cell to fixed tissue, from routine to ground-breaking, the ORCA-Flash4.0 LT is designed to be the new workhorse digital camera. The ORCA-Flash4.0 LT shines with the most experienced implementation of Gen II sCMOS technology, and realizes the long-awaited promise of luxury CCD performance at affordable CMOS price.

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.

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.

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.
