Caeleste will be present on the prestigious Image Sensors Conference .

Caeleste will have a booth and will demonstrate its large full well sensors for low contrast imaging. Caeleste staff is available to discuss your needs in the field of advanced image sensors, (hyper) spectral image sensors and life science sensors. For a more in-depth discussion with our Business Development Manager Jan Vermeiren , please make
an upfront appointment.

Caeleste paper
Ajit Kumar Kalgi, senior design expert at Caeleste, will also present a paper called: “Photon shot noise limited image sensors with Global shutter and linear high dynamic range”.

Dynamic range (the ratio of full well capacity over the noise floor), linearity and dark current are the most important parameters of a good image sensor. Quite often also a global or synchronous shutter operation is added to the list in order to avoid imaging artefacts when looking to fast moving objects, such as e.g. propellers. On the other hand all these additional features should not blow up the pixel size and should not jeopardize the fill factor of the pixel. Caeleste succeeded in integrating all the above elements in a pixel pitch of 6.5 µm. The design and the results will be discussed in depth during the conference, but we give you three images as a teaser.

Photon shot noise limited image sensors with Global shutter and linear high dynamic range

The left image shows the scene in high gain; the propeller blades shows some blur, but the shape is not deformed, as you could expect from a rolling shutter device. The middle image is the low gain image. The right image is the combined high-low gain image after a logarithmic transform to enhance both dark and light features in the image. Please take into account that the high and the low gain images are acquired during the same integration time. In this way the images can be overlaid without any geometric correction.

Staff & JOBS: Looking for more exciting challenges?

In 2016, we already welcomed four new employees to reinforce our image sensor design team, as well as our marketing & sales team. We are growing fast.
And we are still actively searching for senior and junior image sensor designers and IC-layout engineers as well.
More details can be found on
our website and on Linkedin. Do not hesitate to contact us and send us your resume.

Caeleste at Photonics-West (booth 4150)

Caeleste is present at Photonics West, which will be held from 16th till 18th February in the Moscone Center in San Francisco.
We demonstrate one of our high dynamic range sensors, by revealing very low contrast objects in a scene: definitely worth the visit!
Caeleste staff is available to discuss your needs in the field of scientific image sensors and spectroscopic devices.

Caeleste celebrates its 10th Anniversary

In 2016 Caeleste is celebrating its 10th anniversary.
We will organize a special summer event for all our business relations as explicit thank for all the trust our customers have put in us. Caeleste will also organize some broader special events:
• 6th April: Special CMOS image sensor session at the SPIE Photonics Europe in Brussels.
• 14th October: Electronics Olympiade (quiz for everyone working or interested in electronics) in Technopolis, Mechelen.
More information will follow soon.

UV sensitivity in CMOS Image Sensors

The UV range has many applications in industrial, scientific and medical applications, e.g. for hyperspectral analysis or for skin damage measurements from Sun irradiation. High UV sensitivity in linear or even color 2D UV sensor would help a lot in making the correct diagnosis.
Peng Gao and Dirk Van Aken are presenting the results of Caeleste’s realization of a UV-White-Yellow Bayer-like pattern imager on the workshop of the French Space Agency CNES about: “CMOS Image Sensors for High performance Applications

Caeleste at ITE YOKOHAMA on Image technology and Equipment (ITE 2015 booth D-18)

ITE Yokohama

Caeleste will participate to the show on image sensors in Japan: ITE-2015. This show will be held in Yokohama from 2 till 4 December 2015. Caeleste will demonstrate there the capabilities of its high dynamic range sensors and more specifically the possibility to reveal very low contrast objects in a scene. This is done by combining a high full well of the sensor with a high linearity over the full signal range. This property is very important for e.g. forensic research.
When you like to have a more in-depth discussion with Jan Vermeiren or Eiji Watanabe of AlliedSens,please make an upfront appointment.

Caeleste will be present on the Flemish space days

Flemish Space Days

From 20 till 22 November 2015, Caeleste will be present on the Flemish space days. Caeleste is an important provider of image sensors for space applications, where radiation hardness and reliable operation under solar storm conditions is of utmost importance for earth observation missions and for deep space missions.
If you are interested in designing image sensors for this challenging environment, do not hesitate to contact us on Friday 20 November. The present job openings can be found on the Caeleste website.

Semicon Europe – Dresden 6 to 8 October 2015

Meet Caeleste at the Semicon Europe 2015 show in Dresden. Simply pass by our booth 2064 in association with the High-Tech Cluster DSP-Valley. Jan Vermeiren (Business Development Manager) and Karsten Sengebusch (German representative), will welcome you and answer all your requests.
Come and see a live demonstration of our latest very high dynamic range sensors.
Caeleste has built up a considerable experience in high dynamic range sensors for different wavelength ranges from the NIR, over the visible wavelengths range till the UV and X-ray. This has translated itself into many successful designs with dynamic ranges varying between 92 and 140 dB. Global shutter, Anti-blooming and knee-less dual sensitivity are useful extensions to your HDR applications.

When you like to have a more in-depth discussion, please make an upfront appointment.
