High-performance optics

Hensoldt Optronics’ credentials in space applications date back to Carl Zeiss and its legacy of more than

space missions.

Telescope systemThe best in high-performance space optics comes with a label – Hensoldt Optronics. We not only develop and test optical telescopes with up to 1.5 metres diameter; we have even reduced wave-front errors to a few nano metres across

substrates and coatings.

by Hensoldt Optronics on board. Able to perform in some of the solar

system’s harshest environments, these instruments are nothing short of engineering marvels. Hensoldt Optronics’ understanding of high-performance optics for space-bound spectrometer applications runs deep indeed. And that makes our offering the go-to solution for earth observation missions.

Communication poses a formidable challenge for missions in free space. Hensoldt Optronics has found a way

optics and detectors with modulated laser beams to create a network of communication systems in free space.

Space applications


Hensoldt Optronics has for years excelled at designing and building telescope systems for space applications. Our engineering capabilities run the gamut from conceptualisation and optical and mechanical design to manufacturing, alignment and space testing. We join forces with customers to co-develop telescopes ranging from classic Cassegrain and Korsch solutions to innovative off-axis systems and beyond.

As a technology company with a customer-centric mindset, our aim is to tailor the optimum optical solution for each application. Our performance promise demands that we deliver precisely what your

capabilities, f-number, focal length, and many other related parameters dictate. Hensoldt Optronics’ engineering team leverages state-of-the-art optical materials, space-

conditioned mechanical materials to meet these expectations in the lab. And with the help of Carl Zeiss’ manufacturing excellence, we are able to put together the perfect

Space missions expose equipment to one of the most punishing environments known to humankind. Any weakness in material or design

Instrument performance matters in

more so than in space exploration. Now that satellites armed with an arsenal of instruments are setting out into deep space, astronomers are no longer earthbound in their ability to observe the heavens. The demands placed on these devices could hardly be more contradictory: They have to be precisely calibrated and very sensitive, yet rugged enough to defy the fatigue imposed by years of exposure to the most inhospitable conditions.

Many NASA and ESA missions would be all but inconceivable without spectrographs. Combining spectral decomposition and selective imaging capabilities, these instruments are the best probes we have to study the nature of distant stars, galaxies and the remnants of the universe’s primordial history. This requires sophisticated optical

apertures, slicing elements and diffractive elements as well as the ability to perform at cryogenic temperature with arcsec accuracy. Hensoldt Optronics delivers components with precisely the capabilities that space spectrographs need. Built on the bedrock of half a century’s experience in space-borne optics, each component of every solution can be customised to your

Today the planets of our solar system are within easy reach. Scientists have made a giant leap forward over the last decade in their ability to gather intelligence on planetary missions. And Hensoldt Optronics provides the key to correlating this information with topographical data.

This is why a Hensoldt Optronics laser altimeter is on board satellite missions to our neighbouring planets. That very laser will again

The future of data transfer is photonic. Laser-based communication can pack a lot more data and deliver the goods at far faster speeds than radio waves, and at tremendous bandwidths that require no compression. Successful tests in space, over land and under water attest to the viability of laser-light data transmission systems developed by Hensoldt Optronics. Optical communication, with its ability to port data at gigabit speeds, is a boon for any application that relies on network- centric operations.

Tap-proof and free of the constraints imposed by cables and radio frequency licenses, this form of optical communication can span very long distances indeed. A combination of incoherent transmission technology and point-to-point and point-to multi-point topolog ies enables networked communi cation among multiple transmitters and receiving terminals, and raises the availability bar to unprecedented heights.

Hensoldt Optronics’ offering encompasses everything from short- and medium-range stationary devices and fully stabilised equipment systems for mobile applications to underwater solutions and long-throw space applications. All products are compatible and may be networked for any civilian and military terrestrial, marine, submarine, airborne and space-borne scenario.


Laser communication at sea Laser communication in space

Command, control, intelligence and reconnaissance capabilities require reliable means of sharing data with remote units. Today’s answer to this communication question is radio frequency technology. High-resolution detector systems, however, generate a deluge of data that cannot be trans mitted in real time without some form of compression. What’s more, limited frequency bands and antenna size impose severe constrictions on some of the potentially most effective applications, for example, mini drones.

RF technology, with its inability to transport vast streams of data, is fast approaching the point of diminishing returns. It is sure to be edged out by laser-based communication. The higher bandwidth and faster transmission rates will prevail wherever superior surveillance capabilities and immunity are at a premium.

arrived, as this brief recap of Hensoldt Optronics’ achievements attests:

StationaryOur optical communication equipment’s ability to transmit uncompressed HD data for border surveillance applications has proven

applications, there is no other way to blast through the data bottleneck and transcend the gigabit barrier.

The world’s only ground / GEO link is based on Hensoldt technology that is part of our Zeiss legacy. Optical feeder links exploit licence-free bandwidth, thereby sparing licensed frequencies that can be gainfully employed for downlink broadcasts.

MobileHensoldt Optronics is known for its superior stabilised terrestrial, maritime and airborne platforms. The experience and insight gained in these projects has enabled us to develop optical communication systems that deliver reliable broadband performance in the air, on land and at sea.

Today submarine communication is suboptimal, with a threshold not higher than the kbit / s range. Our technology has been proven to transmit data at mbit/s speeds, which opens up a whole new range of possibilities, for example, reconnaissance data sourced from unmanned underwater vehicles. Hensoldt Optronics’ optical underwater acquisition technology is
