Intensifier camera addon
Photek’s ILCI-25 utilizes an MCP125 or MCP225 image intensifier which and provides wavelength conversion and highspeed shuttering. The ILCS-25 is specifically designed as an add-on for existing cameras such as cooled CCD, EMCDD which utilize a Nikon F Mount adaptor.
The ILCS-25 can be programmed using the integral touch screen LCD display and optical encoder or via the embedded USB interface.
The controller is provided with a trigger input and four individually programmable delays and width generator one of which controls the image intensifier gate directly and the other three channels are available as user-configurable outputs. An internal time base is also available.
Integral high voltage power supplies and gate units are also provided.
|Active area||25 mm|
|Input window||fused silica|
|Photocathode||solar-blind, Bialkali, LNS20, S20, S25|
|MCP||MCP125 (single) or MCP225 (chevron)|
|Input mount||Nikon F-mount|
|Output adaptor||52 mm diameter lens mount fitted to housing|
|Internal optics||50 mm F1.2 lens fitted inside housing|
|External input optics||any Nikon F Mount manual lens (not supplied)|
|External output optics||50 mm F1.2 1:1 magnification (Photek can supply lens)
100 mm 2:1 magnification (end user to supply lens)
25 mm 1:2 magnification (end user to supply lens)
Note: External lens must be fitted with a 52mm diameter lens thread. Other diameter lenses can be used, however, a suitable adaptor ring will be required.
|Operating modes||Off, DC On, Internal Time base, External trigger, Pass through|
Gate, T1, T2 und T3 outputs
|Min. gate width||5 ns TBC *|
|Min. gate delay||50 ns|
|Gate and delay steps||5 ns (intensifier control)|
|Gain adjustment||via 12 Bit DAC|
|Screen current trip||200 nA, 400 nA, 600 nA, 800 nA and 1 µA
If screen current is exceeded, intensifier power will be switched off. Intensifier power must be enabled to continue.
* We are able to guarantee a minimum gate width of 10ns, however, we are targeting 5ns as the minimum gate period for this design.
|Source||trigger input or internal time base|
|Trigger input||50 Ohm|
|Trigger edge||+Ve oder -Ve edge of trigger input pulse|
|Max. trigger rate||100 kHz|
|Burst mode||200 MHz, 100 Pulse, then 1 ms off. TBC**|
** We anticipate that a string of 100 pules at 20MHz followed by a dead time of 1ms will be achievable. These figures cannot be guaranteed until the burst has been fully characterised.
|LCD display||incorporates 100mm x 58mm LCD screen with touch input display details: Operation mode, Intensifier Power (off, on, tripped), intensifier gain, internal time base, Gate, T1, T2 and T3 delay and width setting|
|Optical encoder||in conjunction with the touch sensitive LCD, an optical encoder provides a simple and intuitive method for making manual adjustments to the controller|
|Power connector||5 mm Jack socket|
|Dimensions||145 mm (L) x 90 mm (W) x 115 mm (H)
excludes F Mount and connectors
|Power||+12 V DC @ 2 A max, (external power adaptor provided)|
