The pco.dicam C1 combines image intensifier technology with the high performance of a sCMOS sensor. An efficient tandem lens provides the critical optical interface between the high-resolution 25 mm image intensifier and the 16 bit sCMOS sensor. With pco.dicam C1 cameras, it is possible to detect individual photons using the shortest exposure times.

The innovative photonics of this camera series is supplemented with the use of a high-performance data interface, enabling data transmission over long distances via fiber optic cable. These cameras use a Camera Link HS (10G fiber optic data interface) which guarantees the secure transmission of uncompressed data.

Photocathode response determines the spectral sensitivity of the camera.
The following graph, which was obtained with permission of Hamamatsu Photonics, shows the Spectral Sensitivities of different photocathode materials: S20 (multialkali), GaAs, GaAsP.

Photocathodes made of S20 material are responsive in the deep UV region and has a rather wide sensitivity range – up to 800 nm. GaAsP is well suited for the visible range of 450 to 700 nm, and GaAs covers VIS and NIR regions of the spectrum.

As shown in the graph below, the emission wavelengths of both P43 and P46 phosphors are fairly well matched to the QE response of the sCMOS image sensor.

Phosphor selection is typically made on the basis of the dynamics of the intended application. The main differences between the P43 & P46 phosphors are:

  • decay time
  • efficiency

Phosphor efficiency and dynamics

Phosphor Phosphor decay to Peak emission Typical efficiency
10% 1%
P43 1ms 4ms 545nm 100%
P46 0.2 - 0.4µs 2µs 530nm 30%

Various combinations of photocathode materials and phosphors are available within the pco.dicam series of intensified sCMOS cameras. While the P43 phosophor has a much brighter emission than the P46 phosophor, it has a rather long decay time, i.e. the time required until the phosphor emission fades out after the excitation by electron bombardment has been stopped. This decay time is critical for obtaining fast image repetition rates, primarily in double-image (PIV) applications. A slowly decaying phosphor might retain image information from a previous exposure which could add to the image of the next exposure. This has the effect of contaminating an image with information from the previous exposure. The decay time of a phosphor is also critical when operating the camera in spectroscopic mode with line rates in the kHz range.

To summarize:

P43 is a good choice for very low-light applications in which the image is static, or changing very slowly.

For fast applications in which it is desirable to capture multiple images over 1000fps, P46 is a better choice.

In PIV or PTV or other flow visualization application where the double image (double shutter) option may be useful, the P46 is a better choice as it decays to 10% in 200 – 400ns.  

Image intensifiers with GaAs and GaAsP photocathode are offered by the manufacturer in two quality grades:

Standard: The quality of the intensifier is specified for central 16 mm x 16 mm square region corresponding to a central 1300 x 1300 pixel region of the sCMOS sensor.

Selected: The quality of the intensifier is specified for 24.9 mm diameter area corresponding to the full 2048 x 2048 pixel sCMOS sensor area. In addition, the extinction ratio for “selected” grade image intensifiers is 10 times higher than that of “standard” grade.

Image intensifiers with S20 photocathodes are exclusively of “selected” grade, which means that by specifying S20 photocathodes (which are suitable for deep UV up to 800nm), one gains the additional benefit of higher quality AND higher extinction ratio.
