Camera Systems

Listed in this section are the most commonly supplied systems. However, XCAM specialises in using its wide library of subassemblies to create variants on previously supplied systems, so if you would like one of these systems building with a different detector or mechanical camera head, for example, please enquire.

VaCam In-Vacuum Video Camera

Introduction

VacCam was developed in response to frequent requests from customers seeking an in-situ vacuum video camera to internally monitor operations and processes occurring inside the vacuum chamber. It has been designed with vacuum-compatible construction to ensure low outgassing and avoid contamination of your in-vacuum processes or experiments.

The video camera system accepts C-mount lenses and XCAM offers a small selection of vacuumcompatible optical lenses for use with the camera or customers can provide their own.

The camera has mounting points which must be connected to a heat-dissipative mounting block to removed the thermal heat generated.

The camera has a USB2.0 interface for power and communications.

RIXSCAM – A MULTI-EMCCD LARGE DETECTOR AREA SYSTEM WITH SINGLE PHOTON DETECTION AND SUB-PIXEL RESOLUTION FOR SOFT X-RAY DETECTION

XCAM’s RIXSCam™ family of camera systems, consisting of the original RIXSCam™ and the newly-released RIXSCam™ Mini, combine the single-photon detection capabilities of custom EMCCDs with licensed centroiding technology to deliver sub-pixel resolution for RIXS (Resonant Inelastic X-ray Scattering) applications.

All the systems in XCAM’s RIXSCam™ range use the same custom EMCCDs – these are full-frame detectors with 1632x1608 16µm pixels which are back-illuminated with no AR coating to provide an outstanding soft X-ray response.

EMCCDs provide single-photon detection with sub-electron read noise. When cryogenically cooled down to temperatures in the range of -110 to -50 ˚C, as in the original RIXSCam™, dark current and associated dark current noise also becomes negligible, permitting a range of camera operation modes.

The original RIXSCam™ system allows between one and three of these devices to be closely butted (see table below for models) to provide a greater signal-to-noise ratio. The detector assembly is mounted on a rotatable cold bench which can be adjusted through all angles and locked in position from the outside of the camera, enabling the user to reduce the effective pixel size.

Finally, a centroiding algorithm, developed jointly by the Paul-Scherrer Institute (PSI) and the Open University, is applied to the resulting image, providing at output a ‘super-resolution’ image of up to 10 times the original resolution. This provides a resolution of better than 5µm, with better than 3µm having been demonstrated during experimental phases. The ultimate resolution achievable depends on the local experimental set-up as well as the camera system.

RIXSCAM™ Mini

Following the huge success of the original RIXSCam system, XCAM have now released the RIXSCam™ Mini – a single-detector system which utilises a Peltier cooler and has a user-defined fixed gamma-angle for the detector. This allows the same spatial resolution as the original RIXSCam™ system (which has a rotatable cold bench to adjust the angle of incidence with the beam in addition to cryogenic cooling) but at a lower cost to the customer. This is particularly beneficial to beamline scientists whose experiments do not require the same high-throughput as those requiring a multi-detector system. The detector mounting has also been designed to enable the detector to eventually be replaced if needed, providing a long-term economical solution for beamline scientists.

CAVACAM (F) – CAMERA FOR VACUUM APPLICATIONS ON A CONFLAT FLANGE

CaVACam is XCAM’s Camera for Vacuum Applications, developed in response to many enquiries for vacuum ‘clean’ camera systems. The F-model CaVACams are cameras which are essentially built on to a conflat flange and which have entirely ‘vacuum clean’ parts inside the vacuum chamber and the ‘dirty’ electronics and non-vacuum components on the airside of the flange. This camera system is ideal where a conflat flange design suits your application and you do not need to immerse the camera head inside the vacuum chamber.

Whilst we maintain a ‘standard’ build configuration for these camera systems, they are very easily adapted to meet your specific material requirements or even to take different detectors if required, due to the modular design. RGA scan of the camera head can be conducted if required.

Detectors are available in front-illuminated (FI) or back-illuminated (BI) options and BI may be available with no AR coating for good soft x-ray performance – all dependent on availability and MOQ from supplier. Please enquire if the camera configuration you require is not in the list below.

CAVACAM (S) – CAMERA FOR VACUUM APPLICATIONS FULLY VACUUM IMMERSIBLE

CaVACam is XCAM’s Camera for Vacuum Applications, developed in response to many enquiries for vacuum ‘clean’ camera systems. The S model CaVACams are cameras in which the ‘vacuum clean’ parts including the detector are built on the outside of a hermetically sealed camera head, and the non-vacuum components are enclosed inside the sealed chamber. Data is removed from the camera head via clean vacuum fibre optic cables and a single power cable is designed to be vacuum compatible. This camera head is ideal where you need to fully immerse the camera head inside the vacuum chamber and cannot use an F-model CaVACam.

C3D CUBESAT CAMERA

1U+ format CubeSat camera with proven space flight heritage

• Space-flight heritage since 2014
• Compatible with 1U+ format cubesatellites
• Lossless image compression
• Wide-field imager (WFI) camera optics
   ‒ Up to three cameras per imager board
   ‒ Near- and far- field imaging capabilities
   ‒ Colour and/or black & white imaging

C3D is a CubeSat camera system (imager board and optical subassembly) with TRL 9 status and proven space flight heritage. Originally developed in partnership with The Open University, C3D has successfully flown and transmitted images on CubeSat missions such as the UK Space Agency’s UKube-1 and AlSat Nano.

The C3D CubeSat camera system is an imaging payload which can be used for a variety of applications including earth observation (EO) and CubeSat self-monitoring, and has proven success with both of these applications on real CubeSat missions in space.

Flexible design caters to individual requirements

C3D has been designed to be compatible with 1U and larger format CubeSats. The flexible design allows up to three wide field cameras per imager board. Cameras can be coaligned (see product sheet below for diagram) for stereo imaging or to allow for alternative imaging requirements including both near- or far-field and black & white or colour imaging. Images are compressed using a lossless JPEG image compression algorithm to preserve the integrity of your data.

As well as our standard C3D system, enquiries of a custom-design/R&D nature are also welcomed at XCAM; our vast experience and expertise developing custom-design camera systems means we are ideally placed to advise on the best solution for your imaging requirements.
