Laser 2000

ORCA-spark Digital CMOS Camera


The ORCA-spark is a fast, low noise, and high-sensitivity digital CMOS camera. At a significantly lower cost, it out-performs Hamamatsu’s popular interline CCD cameras such as the ORCA-R2.

Noise, in particular, can be an overriding factor in many experiments. Fluorescence from your samples can sometimes get lost in a sea of ambient photons, autofluorescence, or even camera readout noise. In addition, fluorescence photons in low-light conditions can become over- or underexposed and, therefore, inaccurately recorded.

The low readout noise (6.6 electrons) and wide dynamic range (5,000:1) afforded by the 2.3 megapixel CMOS sensor means that the ORCA Spark will accurately record fluorescence signals, even in noisy or low-light conditions.

We know it can be challenging to accurately capture fast-moving samples. But this isn’t an issue when imaging with the ORCA-spark. It has a global shutter, and achieves a high-speed readout of 65 frames per second, so you can image fast-moving objects without blurring.

Solutions that balance cost and performance is what we specialise and take pride in at Laser 2000. And with the ORCA-spark, you won’t be disappointed.

Here are some example applications that the ORCA-spark thrives in:

  • Low-light-level imaging
  • Microscope observation
  • X-ray scintillator readout


  • 2.3 megapixel CMOS sensor
  • High-speed readout of approx. 65 frames/s
  • Low readout noise of 6.6 electrons
  • Wide dynamic range of 5000 : 1
  • Global shutter
  • USB 3.0 interface


  • Low-light-level imaging
  • Microscope observation
  • X-ray scintillator readout


What’s included?

The ORCA-spark package contains all the accessories required to communicate with your PC, including:

  • 1 x USB 3.0 board
  • 1 x USB 3.0 Micro-B cable

HCImage Live software is included at no extra cost. However, you can also operate the camera using third party software such as µManager and LabVIEW in conjunction with your microscope and peripheral devices.
