The Ultraviolet Transient Astronomical Satellite (ULTRASAT) is a scientific space mission carrying an astronomical telescope. The mission is led by the Weizmann Institute of Science (WIS) in Israel and the Israel Space Agency (ISA), while the camera in the focal plane is designed and built by Deutsches Elektronen Synchrotron (DESY) in Germany. Two key science goals of the mission are the detection of counterparts to gravitational wave sources and supernovae.1 The launch to geostationary orbit… 

Design of the ULTRASAT UV camera

The Ultraviolet Transient Astronomical Satellite (ULTRASAT) is a scientific UV space telescope that will operate in geostationary orbit. The mission, targeted to launch in 2024, is led by the

The scientific payload of the Ultraviolet Transient Astronomy Satellite (ULTRASAT)

The Ultraviolet Transient Astronomy Satellite (ULTRASAT) is a space-borne near UV telescope with an unprecedented large field of view (200 deg2 ). The mission, led by the Weizmann Institute of

A small dedicated UV telescope with a modern detector can obtain a lot of new information to study comets in the UV range, which is inaccessible for ground telescopes. We discuss the latest trends in

A low-cost ultraviolet-to-infrared absolute quantum efficiency characterization system of detectors

We present a low-cost ultraviolet to infrared absolute quantum efficiency detector characterization system developed using commercial off-the-shelf components. The key components of the experiment



Non-linear responsivity characterisation of a CMOS Active Pixel Sensor for high resolution imaging of the Jovian system

The Jovian system is the subject of study for the Jupiter Icy Moon Explorer (JUICE), an ESA mission which is planned to launch in 2022. The scientific payload is designed for both characterisation of


The time-variable electromagnetic sky has been well-explored at a wide range of wavelengths. In contrast, the ultra-violet (UV) variable sky is relatively poorly explored, even though it offers

Angle-of-incidence effects in the spectral performance of the infrared array camera of the Spitzer Space Telescope

The Infrared Array Camera (IRAC) on board the Spitzer Space Telescope uses two dichroic beamsplitters, four interference filters, and four detector arrays to acquire images in four different channels

SCALA upgrade: development of a light source for sub-percent calibration uncertainties

The SCALA system provides a physical flux calibration for the SuperNova Integral Field Spectrograph (SNIFS) mounted to the University of Hawaii 2.2m telescope on Mauna Kea by transferring the flux

Characterization of photodiodes as transfer detector standards in the 120 nm to 600 nm spectral range

Using spectrally dispersed synchrotron radiation of continuously tuneable wavelength as delivered by the ultraviolet (UV) and vacuum ultraviolet (VUV) calibration facility of the

Absolute silicon photodiodes for 160 nm to 254 nm photons

Silicon n-on-p photodiodes with 100 % internal quantum efficiency have been studied in the 160 nm to 254 nm spectral range. Preliminary values have been determined for the quantum yield of silicon at

A system and methodologies for absolute quantum efficiency measurements from the vacuum ultraviolet through the near infrared.

The system design and methodology for making absolute quantum efficiency (QE) measurements through the vacuum ultraviolet (VUV) is presented and the system with delta-doped silicon CCDs is verified.

Characterization and measurement results of fluorescence in absorption optical filter glass

Optical filter glasses (absorption filters) are for example used for spectroscopy. The filter glass absorbs the unwanted light and has a nearly angle independent spectral characteristic. The absorbed
