The OOEL provides expert advice with a state-of-the-art laboratory to:
OOEL provides services in the following domains:
Stray light (angle-resolved scatterometry and BSDF) with data analysis
Related fields of interest for the laboratory include fibre optic communication links as well as fibre optic sensor networks serving as a satellite's nervous system, optical multiplexing techniques, advanced detectors and arrays and the effects of the space environment on opto-electronic devices.
The laboratory's current emphasis is on characterising and/or calibrating detectors and small cameras, optical components, laser beams and other optical signals.
It includes a Class 10,000 (ISO 7) cleanroom, two fully equipped optoelectronics laboratories designed for the operation of Class 4 laser systems (defined as powerful enough to burn skin, cause permanent eye damage or ignite flammable material), workshop and storage rooms.
It has the equipment necessary to measure the optical spectrum, beam profile, power and energy, stability and modulation response, in free space as well as optical fibres.
Calibration facility is intended to calibrate and support the on ground calibration campaigns of small instruments, sub-systems etc
Calibrated Integrating Sphere
Sun Simulator (radiance exitance about 4-6x 1014 [photons cm-2 nm-1 s-1])
Photodiodes and spectrometers
CW tunable laser source
The detector characterisation facility is used to characterise CCD detectors and cameras for Earth observation payloads. It is also used to optimise detector operations, produce custom readout electronics and as the ability to conduct cryogenic tests down to 100K and radiometric illuminations using QTH lamps, filters, LEDs or spot projectors amongst others.
Testing bare CCD detectors
Optimisation of detector operation and data validation
Custom readout electronics
QTH Lamp, filters and variable / Aperture Various LEDs, CW or pulsed / Spot Projector
The Optical Ground Station, based in Tenerife, supports the in orbit testing of optical communication terminals. The station has a 1m telescope, can conduct realistic atmospheric test paths and optical feeder links for telecommunications satellites.
Straylight characterisation of optical components is a critical parameter used to compute the overall straylight on instrument level.
Optical metrology is an extremely versatile laboratory inspection tool, and has an important role to play in the verification of quality for optical surfaces. Laser interferometers support and enable the most demanding metrology applications and can characterize the Surface form and Wavefront error of optical components, such as lenses or mirrors.
Optical surface quality and topography are complementary inspection techniques of optical surfaces.
