Time-Resolved iCMOS

The TRiCAM is an intensified CMOS camera for scientific and industrial applications that require 1) low-light level imaging, 2) ultra-short exposures through fast gating, and/or 3) frequency domain imaging using lock-in detection. The TRiCAM features a fast CMOS sensor that is fiber-optically coupled to an image intensifier for optimal transmission efficiency. The high sensitivity of the TRiCAM, down to the single photon level, is supplemented with an acquisition speed up to 162 fps.

The TRiCAM (Time-Resolved intensified CAMera) is the best choice for ultra-fast imaging in the time domain and/or frequency domain.

For time-domain imaging the iCMOS is equipped with an integrated timing pulse generator and gate-unit (TRiCAM G). The TRiCAM G includes the LI-Capture software for control of gate width, gate frequency, delay, gain and binning. Two synchronised TTL output signals (output A and B) are provided for driving pulsed lasers or LEDs.

For frequency domain imaging the iCMOS supports gain modulation of 120 MHz (standard) and higher (external signal generator). This is the TRiCAM M model. Modulation is provided by a single-chip digital synthesizer to ensure a very low phase noise. The TRiCAM is the key component of the Lambert Instruments LIFA system for FLIM.

The TRiCAM is highly customizable and can be equipped with the image intensifier that best matches your application. Different camera models covering a range in spectral sensitivity, phosphor, spatial resolution, gain, linearity, minimum gate width and gating frequency are available.

Intensified CMOS cmaera layout

When the TRiCAM is mounted to a microscope or lens, the incoming light (a) is focused onto the entrance window of the image intensifier (b). The image intensifier converts the optical image to electrons, amplifies this electron image, and re-converts the electrons into photons. A fiber-optic taper (c) guides the amplified optical image to the CMOS module for registration and read-out (d).

For time-resolved imaging the image intensifier is used as an electro-optical shutter during the process of image acquisition. This uses either a signal generated by the gate unit and timing unit (e & f - the TRiCAM G model) or a high-frequency modulation signal (g - the TRiCAM M model) provided by a direct digital synthesizer. The camera provides multiple output signals (h) for accurate synchronization of external equipment such as a pulsed light source.

Image Intensifier

Low-light imaging

The TRiCAM has a built-in image intensifier that boosts the incoming light. This way, you can capture detailed images in the most challenging light conditions.

Our experienced engineers will help you pick the right image intensifier for your application.

Image intensifiers

An image intensifier boosts the intensity of the incoming light.

By converting photons to electrons and back to photons, the

light intensity can be increased significantly. Another feature of

an image intensifier is that it can act as an ultra-fast shutter.

Photocathodes

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.

Gating

The TRiCAM G can be used as an ultra-fast electro-optical shutter by gating the image intensifier and thereby reducing the effective exposure time. Time domain gating eliminates motion blur and significantly widens the range of light levels at which the camera can be used.

The user has full control of the camera gate pulse width, delay and gain through either the dedicated LI-Capture software or the software SDK. The software supports an array of gating modes, including synchronization of the internal oscillator to an external source. The standard camera has two additional output channels (output A and B) synchronised with the gate frequency. For both channels the user has control of the delay time as well as the pulse width and polarity.

For the TRiCAM M model the camera modulation signal at frequencies below 100 kHz can be produced using the optional gate unit and timing pulse generator. The pulse generator also generates the synchronisation signal for a modulated light source or acousto-optic modulator.

Modulation control unit specification

The TRiCAM M provides highly accurate frequency-domain imaging with high-resolution gain modulated Gen II and Gen III image intensifiers.

The TRiCAM M combines the ICMOS camera with a separate modulation control unit. The modulation control unit contains a single-chip dual channel DDS for generation and amplification of the RF modulation signals for the modulated lightsource and the image intensifier (100 kHz – 120 MHz standard). The control unit further supplies the required high-voltages to the image intensifier. A software SDK is provided for digital control of the gain, modulation and cathode bias voltages via an USB interface, emulating a standard RS232 serial communicationsport.

Modulation frequencies below 100 kHz are supported by the optional gate unit and time pulse generator. The pulse generator generates the synchronisation signal for an external modulated light source or acousto-optic modulator.

Phosphors

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.

PHOSPHOR	EMISSION	EFFICIENCY (E/KV)	DECAY TO 10%	DECAY TO 1%
