Abstract Quantum communication has seen rapid progress towards practical large-scale networks, with quantum key distribution (QKD) spearheading this development. While fibre-based systems have been shown to be well suited for metropolitan scales, sui

Sub-aperture fabrication techniques such as diamond turning, ion beam figuring, and bonnet polishing are indispensable tools in today’s optical fabrication chain. Each of these tools addresses different figure and roughness imperfections correspond

Modern grating imaging spectrographs typically show aberrations due to the nonlinear dependence of angular dispersion on wavelength. This error can be reduced by a combination of diffracting and refracting components (grating and prism). Here, we pre

Defect free direct bonding of rigid and large area glass samples, such as prisms, becomes increasingly important for the manufacturing of modern optical and optomechanical components. Typically, in order to apply a static load during the annealing st

2021 7th International Workshop on Low Temperature Bonding for 3D Integration (LTB-3D).
Here, we tackle the paradigm that direct bonding of planar wafers is not suitable on non-planar substrates. In doing so, we also present a new method for measuring the interface surface energy. This yields first guidelines for manufacturing novel opt

The high precision Slit Assembly is a key component of the FLEX instrument. Two different input beams for the Low- and the High-resolution spectrometer, respectively, will be generated by the Slit assembly. The paper presents design and implementatio

For the manufacturing of space-qualified spectrometric applications, the benefits of direct bonding are highly promising. While there are some recent spectrometric design concepts which rely on the usage of optical coatings, the direct bonding of opt

Material Technologies and Applications to Optics, Structures, Components, and Sub-Systems IV.
Mirrors with excellent mechanical, thermal and optical properties are suitable for a broad spectrum of modern optical application. A growing number of multi- and hyperspectral imaging devices such as telescopes and spectrometers are based on all-refl
