Lenses and optics DL-Series of Delay Line Kits Foturan II
Schott has announced the improved photo-sensitive glass Foturan II, a material characterised by advanced photosensitivity and homogeneity. These unique properties combined allow a high aspect ratio, and therefore enable radio frequency (RF) components and microelectromechanical systems (MEMS) manufacturers to create substrates with significantly finer structures for various semiconductor and biotechnology applications. For more than 30 years, Schott’s
Foturan glass has been a proven speciality glass material whenever extremely fine structures are needed without the effects of regular resist-based photolithography. Foturan II is available in 6- or 8-inch round
wafers and square substrates up to 200 x 200mm with thicknesses between 0.5mm and 1mm. The wafers are structured and processed in three steps: UV-exposure (with standard lithography equipment without the use of photo-resist), tempering (heat treatment), and etching.

Scintinel crystalline stilbene
Inrad Optics has launched Scintinel branded stilbene scintillation crystals. These crystals include a product suite of off-the-shelf stilbene cylinders and custom shapes and sizes up to four inches. Scintinel crystals can be ordered standalone, wrapped in PTFE or packaged in an aluminium canister for easy integration with photomultiplier tubes.
Stilbene is a scintillator that emits light in the presence of nuclear radiation. Advantages of this solid-state, non-hazardous material include high sensitivity to neutrons and excellent discrimination between neutrons and gamma-ray radiation.

Linos double BBO high-repetition Pockels cells
Qioptiq has introduced its Linos Double BBO High-Repetition Pockels Cells (DBBPC HR), featuring two crystals in an optical series to enable fast switching rates with up to 1.3MHz performance. The DBBPC HR series Pockels cells are designed for fast Q-switching as required in regenerative amplifiers or for pulse pickers. Applications for the new Pockels cells include use in ultra-fast lasers for micro material processing, ophthalmology, and fluorescence spectroscopy, as well as by laser manufacturers and scientific institutes.
Conventional BBO Pockels cells suffer from piezo ringing at high switching rates (several hundred kilohertz), which generates excess heat leading to poor performance and damage. Superior thermal management of the DBBPC HR design eliminates any requirement for additional cooling, also allowing fast tuning of the switching rates. Together with low absorbing BBO crystals, the cells are suited for the next generation of fast, high-power regenerative amplifiers and pulse pickers. Customer-specific wavelengths are also
available upon request.

Newport’s DL-Series of Delay Line Kits provides scientists and researchers with all the necessary components to build a complete optical delay line. These pre-selected kits are a convenient and economic solution for a wide range of applications where the delay between two or more light pulses needs to be varied by increments in the femtosecond or nanosecond regime.
The DL100 and DL200 kits are designed for experiments requiring delays up to 1,333ps. Both kits are based on Newport’s compact FCL Series Stepper Motor Linear Stage with either 100 or 200mm travel range. They come fully equipped with a broadband retroreflector (450-10,000nm) that ensures an always perfectly parallel reflected beam with no need for adjustments. All optics and opto-mechanical components required for the setup are included. All four Newport DL-Series kits are equipped with Suprema Series steel mirror mounts
Tip/tilt/piston devices
Mirrorcle Technologies (MTI), the California- based manufacturer of patented, gimbal-less micromirrors, has announced the commercial availability of tip/tilt/piston devices fully supported by a plug-and-play development kit. The company’s MEMS-based beam-steering micromirrors now feature ‘third dimension’ agility – in addition to tipping and tilting the X and Y
for long-term stability. They also come with numerous iris apertures to facilitate the precise alignment of the laser beam to the delay line. An additional Suprema mount for reflecting the beam back to the experiment completes the kits.

axes, these devices are now available with a third, pistoning movement. Mirrorcle Technologies has been offering high- quality dual-axis MEMS mirror devices for mor than a decade, with its unique, proprietary gimbal- less design that offers not only highest speed tip/ tilt capability but, thanks to the freely suspended actuator stage, also pistoning or z-axis freedom.
