“…Examples of optical materials used for stable optical assemblies are fused quartz [1], silicon carbide, and glass ceramics like Zerodur [2][3][4]. The study presented here focuses on optical systems based almost entirely on Zerodur which is particularly well-suited for applications requiring a broad operating temperature range due to its low thermal expansion coefficient of 0.02 × 10 −6 K −1 .…”

Operating ultracold quantum gas experiments outside of a laboratory environment has so far been a challenging goal, largely due to the lack of sufficiently stable optical systems. In order to increase the thermal stability of free-space laser systems, the application of nonstandard materials such as glass ceramics is required. Here, we report on Zerodur-based optical systems which include single-mode fiber couplers consisting of multiple components jointed by light-curing adhesives. The thermal stability is thoroughly investigated, revealing excellent fiber-coupling efficiencies between 0.85 and 0.92 in the temperature range from 17°C to 36°C. In conjunction with successfully performed vibration tests, these findings qualify our highly compact systems for atom interferometry experiments aboard a sounding rocket as well as various other quantum information and sensing applications.

“…Here, flint glass was used for the lens in Group 2 with negative power and crown glass was used for the lenses in Group 3 with positive power to minimize the color aberration of the entire system [33]. However, the performance of the entire lens is still low even though Seidel aberration was corrected.…”

In optoacoustic (photoacoustic) systems, different echo signal intensities such as amplitudes, center frequencies, and bandwidths need to be compensated by utilizing variable gain or time-gain compensation amplifiers. However, such electronic components can increase system complexities and signal noise levels. In this paper, we introduce a double-Gauss lens to generate a large field of view with uniform light intensity due to the low chromatic aberrations of the lens, thus obtaining uniform echo signal intensities across the field of view of the optoacoustic system. In order to validate the uniformity of the echo signal intensities in the system, an in-house transducer was placed at various positions above a tissue sample and echo signals were measured and compared with each other. The custom designed double-Gauss lens demonstrated negligible light intensity variation (±1.5%) across the illumination field of view (~2 cm diameter). When the transducer was used to measure echo signal from an eye of a bigeye tuna within a range of ±1 cm, the peak-to-peak amplitude, center frequency, and their −6 dB bandwidth variations were less than 2 mV, 1 MHz, and 6%, respectively. The custom designed double-Gauss lens can provide uniform light beam across a wide area while generating insignificant echo signal variations, and thus can lower the burden of the receiving electronics or signal processing in the optoacoustic system.

“…On introducing additional chemical elements the range of index of refraction and dispersion combinations has been extended largely. Fluoride and fl uorophosphates glasses, borosilicate, barium-and lanthanum-containing glass types add low dispersion variants for given refractive index levels [2] .…”

Glass has been in use for more than 5000 years. Within the past 130 years it became the subject of scientifi c advancement towards a material of precisely predictable and reproducible properties. As such, it was a crucial element in the technical revolutions of the 19th and 20th centuries. However, glass development did not stop. Today, environmental and not least economical aspects play an important role in the dramatic change of glass materials and their availability. Almost 90 % of glass types have vanished from catalogs in recent decades, whereas new materials are being rapidly developed.
