Introduction
The document introduces the ORCA-Flash4.0 LT PLUS, a scientific CMOS (sCMOS) camera designed for researchers transitioning from traditional CCD cameras. It highlights the camera's affordability, performance, and suitability for experiments requiring simple connectivity, moderate frame rates, and high sensitivity.
Specifications
The ORCA-Flash4.0 LT PLUS features a scientific CMOS image sensor with 82% peak quantum efficiency at 560 nm. It has a cell size of 6.5 μm x 6.5 μm and an effective pixel count of 2048 x 2048, covering an area of 13.312 mm x 13.312 mm. The readout noise is reported as 0.9 (median) and 1.5 (rms) electrons. The camera operates at a cooling temperature of +10 ºC and has a dark current of 0.6 electrons/pixel/s. It supports a frame rate of 30 fps at full resolution, a full well capacity of 30,000 electrons, and a dynamic range of 33,000:1. Binning options include 2x2 and 4x4, with a 16-bit digital output and USB 3.0 interface.
Trigger and Output Features
The camera includes various trigger inputs and timing outputs, such as edge, level, synchronous readout, and start trigger. It supports global reset and W-View mode with different exposure times. Output signal ports provide continuous high/low output and multi-channel sync.
Quantum Efficiency Curves
The document includes a graph showing quantum efficiency across different wavelengths, indicating performance for various fluorescent dyes like EGFP, mCherry, YFP, DAPI, Cy3, and Cy5.
Additional Information
The document notes that product availability may vary based on local technical requirements and regulations. It also includes contact information for Hamamatsu Photonics offices worldwide.
