Hamamatsu Orca Fire Back Thinned 10.5 MP Camera
Elemental for Discovery
The ORCA-Fire intelligently integrates all the essential elements of a high performance, back-thinned, scientific CMOS (sCMOS) camera. The camera’s excellence is rooted in Hamamatsu’s dedication to low noise and high quantum efficiency sCMOS technology. With the ORCA-Fire, high sensitivity is realized while also achieving excellent resolution and blazing fast speeds. The ORCA-Fire shines when the science demands high throughput but the sample can only deliver a few photons.

Optimize your optics to maximize resolution
Low mag imaging (<40×) offers the advantage of wide field of view, which can be critical for high throughput applications. To acquire low mag images with maximum information, the imaging system must achieve high resolution by matching pixel size to Nyquist-level or higher sampling rates. The pixel size of the ORCA-Fire is ideal for most 40× objectives or lower (see chart below). The ORCA-Fire’s high spatial resolution combined with a large pixel array and high speed readout delivers 2.9× higher pixel throughput over even the fastest 4.2 MP 6.5 μm sCMOS camera.
