ORCA-Halo sCMOS camera
C17440-20U
The ORCA-Halo is an entry-level camera with a back-illuminated sCMOS sensor. Although it is an entry-level model, it offers high sensitivity and resolution, as well as a wide field of view and low readout noise. This camera can be used for a wide range of applications and is designed for those who want to obtain high performance easily and integrate it into their equipment.
ORCA is a registered trademark of Hamamatsu Photonics K.K. (China, EU, France, Germany, Japan, UK, USA).
Features
High QE
By adopting a back-illuminated sensor, we have achieved a high quantum efficiency of 86% (Peak QE). This contributes to the improvement of the S/N ratio.
Spectral response
Low readout noise
ORCA-Halo offers a wide range of settings to adjust readout noise according to the sample.
Typical readout noise
| Camera setting | RMS ［electrons］ |
Median ［electrons］ |
|---|---|---|
| 16 bit standard/Analog gain ×1*1 | 1.6 | 1.2 |
| 16 bit standard/Analog gain ×8 | 1.3 | 0.9 |
*1 Factory settings
High resolution & wide field of view
ORCA-Halo features a sensor with a pixel size of 3.76 μm, which is one of the smallest pixel sizes among our sCMOS cameras. Additionally, it has a high resolution of 3000 pixels × 3000 pixels, allowing for the capture of clear and detailed images.
Measurement Examples
Software
Our software provides the interface to access all of our carefully engineered camera features, from simply setting exposure to orchestrating complex triggering for multidimensional experiments.
