High-speed Image Intensifier
The HiCATT is an intensified camera attachment specifically designed for use in combination with high-speed cameras. It can be used to amplify low light level images to a level up to 10000 times, thereby boosting the sensitivity of the attached high-speed camera and enabling high-speed, low light-level imaging. The HiCATT attaches to all major brand high-speed cameras by using a high-quality lens coupling.
The hybrid Image Intensifier of the HiCATT consists of 2 stages and can be delivered with a diameter of either 25 mm or 18 mm. The first stage is a Gen II or Gen III proximity-focused MCP intensifier and offers a very high, adjustable gain. The second stage is a proximity-focussed Gen1 booster, producing the extra high output brightness required for imaging at high frame rates. In its gating mode the first stage functions as a fast electro-optical shutter with effective exposure times down to the nanosecond regime. The intensifier can be operated at repetition rates of up to 2.5 MHz in burst.
With a wide range of Gen II and Gen III image intensifiers the HiCATT offers high sensitivity down to single photon level and the optimal spectral bandwidth for your application. Different models covering a range in spectral sensitivity, phosphor, spatial resolution, gain, linearity, minimum gate width and gating frequency are available.
Standard, the first stage image intensifier of the HiCATT is equipped with a single MCP. Dual MCP image intensifiers are available on request.

1a. Recording a blue gas flame from a Bunsen burner at high frame rates poses a challenge. The light intensity of the flame is low and to be able to see any details, especially in close-ups, very short exposure times are required.
1b. Recording made with a standard high-speed camera at 1000 fps and 1 ms exposure time. On the one hand, a long exposure time is needed to increase the sensitivity of the camera. On the other hand, a short exposure time is necessary to prevent motion blur.
1c. Recording made with the HiCATT in front of the high-speed camera at 2000 fps and 15 µs exposure time (using gating). The HiCATT makes it possible to capture flames at frame rates up to 300.000 fps. By using gating fast electro-optical shutter function of the image intensifier, the exposure time can be limited to a value at which motion blur is no longer an issue.
2. Recording sequence made with the HiCATT in combination with a high-speed camera. The recording shows a combustion cycle of a fuel injection engine at 22.000 fps.
For time-resolved imaging a gate unit (f) is used together with the image intensifier to yield an electro-optical shutter. The gate unit either generates a high voltage pulse signal or follows an external TTL pulse. The pulse width is variable and follows a TTL input pulse over the range from less than 3 ns to DC at a repetition rate up to 300 kHz.
These photons are guided by a fiberoptic faceplate (3) to the entrance of the second stage (booster).
Again photons are converted to electrons by the photocathode (4) and accelerated to the anode screen (5) where the image appears. The relay lens (6) transfers the image from the back of the intensifier onto the mounted camera.

The HiCATT can be used as an ultra-fast electro-optical shutter by gating the image intensifier. This eliminates motion blur and reduces the effective exposure time, thereby significantly widening the camera’s dynamic range. To prevent loss of intrascene dynamic range when using a shorter gate the user can set a higher MCP gain. The pulse width and frequency are user defined: any pulse width from DC down to a few nanoseconds can be applied.
The table below summarizes the range of different intensifier control units available for the HiCATT.
● The gain control models act as a power supply for the image intensifier, gate pulse trains are supplied
● The gate control model has its own pulse generator, giving the user direct control of the gate width and
● The gate generator models have an enhanced version of the pulse generator with lower jitter. These
models allow the image intensifier to be synchronised to the exposure time of the camera by supplying
a trigger signal.
● All models allow the gate frequency to be set by an external TTL signal.
Microsoft Windows control software is provided with all control unit models, except the manual model. The software provides full user control of the pulse width and delay, gating mode, and intensifier gain. The control unit is connected to the computer via USB (RS-232 is optional). For integration in third party software a full command set is available.
The enhanced pulse generator of the gate generator models has 4 independent programmable pulse outputs (one of which is used for gating) that provide precise timed TTL pulses with pulse widths down to less than 3 ns (FWHM).
The intensifier gate generator is optionally available with programmable gate patterns. A frame storage facility allows storing many different delay/width-settings and the creation of cenarios of freely definable gate sequences.

The HiCATT can be supplied with an optional mechanical shutter for preventing damage to the image intensifier by high intensity stray light or direct laser light. It is further recommended to close the shutter between measurements to increase the lifespan of the image intensifier.
The shutter replaces the original F-mount adapter of the HiCATT. The back focal distance of the F-mount input is unchanged so any F-mount objective can be used. The shutter comes with a power supply and a remote control. A timer can be used to automatically close the shutter after a predetermined time. The remote control has an ergonomic design and a large LCD screen. The shutter can also be controlled by the software of the HiCATT or by an external TTL signal.

The photocathode is the entrance of the image intensifier. This is where the incoming photons are converted to electrons. The quantum efficiency of the photocathode material specifies how efficient this conversion is for each wavelength.
Second generation image intensifiers
The photocathode of a second generation image intensifier can have a quantum efficiency of up to 25%.
S25 photocathodes are only available in the 18 mm diameter image intensifiers.

Typical quantum efficiency (%) of third generation image intensifiers as a function of wavelength (nm).
Phosphor Decay Time
The anode screen of the image intensifier contains a layer of phosphorescent material. Upon impact of an electron, the phosphor screen will emit light. Depending on the type of phosphor, the intensity of the emitted light will decrease faster. The more efficient the phosphor, the slower its light intensity decays after excitation.
Our time-resolved cameras and camera attachments use P43 phosphor. The high luminous efficiency of this phosphor increases the light levels at the output of the image intensifier. This increases the quality of the resulting image.
Our high-speed cameras and camera attachments use P46 phosphor. This phosphor has a short decay time, so the light signal of consecutive frames doesn't get mixed up.
P47 phosphor is available on request, when even faster decay times are required.
