Lasers

Particle imaging velocimetry (PIV)​​ is a non-intrusive, laser optical measurement technique used in research and diagnostics of flow turbulence, microfluidics, spray atomization, and combustion processes. Particle imaging velocity measures the entire region within the flow with simultaneous measurement of its velocity.

A range of​​ Laser Quantum​​ lasers are suitable​​ for this application:

ID Quantique​​ is proud to have contributed to​​ an​​ experiment that demonstrated the computational advantage of a quantum computer over​​ a​​ classical computer!​​ The experimental setup included​​ two SPAD-based ID230 single-photon detectors​​ produced by ID Quantique.

Many of their lasers​​ are suited perfectly to the needs of Raman spectroscopy and microscopy:

Read about the various advantages that 21st century technology can offer to this vital healthcare field in an article entitled “High-Precision Laser Therapy Transforms Dentistry.”

This paper points out the positive results of CO2 gas lasers, such as those produced by Access Laser.

Holography​​ is a technique that images objects in such a way that they appear three dimensional (3D) when viewed later.

The torus family lasers from Laser Quantum are ideal for all holography applications as the beams have long (>100 m) coherence lengths, divergence, and the mode stability that only active locking provides:

  • torus 532 nm  Green Single Longitudinal Mode (SLM) laser with active mode locking

  • torus 660 nm— Red SLM laser with active mode locking

Optics

Image of optical filter sets for Raman applications

Raman spectroscopy filters from CNI Optoelectronics Tech  ensure high transmittance of the Raman scattering spectrum, while filtering out high-intensity laser light.

Features of these filters include:

  • High optical density

  • High transmittance

  • Ultra-steep edges

  • Low wave number

  • High laser damage threshold

  • Long life time

The PAVOS+ line of Faraday devices from Electro-Optics Technology (EOT) has been redesigned offering new customizability and features.

Features include:

  • Variety of polarizer options

  • Low thermal lensing

  • Ultra-low outgassing

  • Fine tuning for peak isolation at operating wavelength, temperature, and power

Image for beam splitter use cases

Diffractive beam splitters, or multi-spot elements, are a family of diffractive optical elements (DOEs)​​ that split an incoming laser beam into an array of beams with controlled separation angles.

A diffractive beam splitter is especially suitable to increase throughput of high-power laser micromachining applications, such as multi-channel scribing and ablation, laser multi-hole drilling, and laser perforation of packages.

For more information about this or other Holo/Or products, contact Holo/Or.

An article about Multiband Optical Filters for telecom, written by two product group managers of Iridian Spectral Technologies, explains “how dual and multiband optical filters are helping to enhance the complexity, footprint, performance, and cost of fiber network components.”

Scientists utilized Holo/Or’s diffractive beam splitter 2×2 (MS-724-1-Y-A) for​​ parallel MPE fabrication of scaffolds​​ in a cancer research application that mimics the ECM of native tissues. Cell biological investigations can now occur at speeds several times faster than by single point scanning methods.

Manx Precision Optics (MPO) has released a new Technical Note entitled “Polarisation and Polarisers.” This paper discusses the science behind polarised waves, as well as implications and applications that this phenomenon provides to the field of optics.

MPO manufactures coated opticsuncoated optics, and polarisation optics.

Image of microlens array

A microlens array (MLA) is an​​ optical component that consists of a set of micron-scale lenses, arranged and “packed“ together on a single supporting substrate. MLAs are used in many photonics-based devices for various applications.

Holo/Or offers a microlens array with 100% “packing,” that is covering the entire surface with no gaps between the lenses, to ensure maximum energy efficiency and optimal zero-order homogenization. Holo/Or also offers broadband diffusers (BD), also known as engineered diffusers, which are a unique type of microlens array with a non-uniform arrangement, presenting much better shaping uniformity compared to a single lens array.

❂Cameras & Imaging

Scientists have built a​​ facility for Resonant Soft X-ray Scattering (RSoXS) to measure nano-scale soft matter structures. A key component of this setup is a low-noise CCD detector from​​ greateyes. The greateyes ALEX 4k4k camera is similar to the one used.

❂Detectors

Photonis designs and manufactures superior detectors for residual gas analysis (RGA).These detectors support RGA in mass spectrometry by providing higher sensitivity in both portable and stationary RGA systems. By equipping your mass spectrometer with a residual gas analyzer, you will be able to detect leaks that​​ prevent​​ achieving proper vacuum.

The new ID281 Superconducting Nanowire offers 16 fiber-coupled single photon detectors with detection efficiency approaching 100%. It is ID Quantique’s ultimate combination of high-performance single-photon detectors based on superconducting nanowires, simple and robust cryogenics, and best-in-class time-tagging and control electronics.
