IXDICE 1342ย from​​ Xiton Photonics​​ is a high repetition-rate, solid-state, diode pumped, Q-switched laser with the unique fundamental wavelength of 1342 nm. It is the successor of the IDOL-C-1342 laser in a more compact laser housing.

Each laser is optimized for high pulse repetition rates in range 40โ€“200 kHz to allow high throughput for material processing applications. Due to the high pulse-to-pulse stability and a sealed housing, the IXDICE 1342 is perfectly suited for continuous 24/7 industrial use.

Applications for this laser are:

  • Stealth dicing

  • Wavelength-sensitive processes

  • Micro-machining

  • Silicon processing

CNI Optoelectronics Techย providesย high power laser diode modules.

These laser modules feature the following:

  • Wavelength range 375โ€”1550 nm

  • High output power up to 500 W

These devices are suitable for these applications:

  • Fiber laser

  • Solid-state laser pumping

  • Direct diode material processing

  • Surgical lasers

  • Medical therapeutics

The broad array of IR sensing applications creates complex and diverse demands. However, all IR devices​​ โ€”​​ from gas leak detectors to IR spectrometers​​ โ€”​​ require imaging filters designed to transmit desired wavelengths selectively. Hence it is essential to address the unique challenges​​ of​​ IR filter optical design.

With a wealth of experience since 1998,​​ Iridian Spectral Technologies​​ has been able to tackle the challenges ofย IR sensing optical design. Iridian has integrated automation into their processing and handling, thus reducing costs and increasing efficiency. Additionally, a reflexive approach to manufacturing ensures high-performance filters with precise specifications.

Filter sets are usually named for the fluorophoreย for which they are recommended but can be useful with many others in the same spectral range. You will need to know a variety of information​​ if planning to use fluorophores, such as excitation (absorption) and emission peak wavelengths, light source, microscope, and detector. You will also need to know which other fluorophores will be present so that the filter can help you detect only the desired fluorophore(s).

Chroma Technology​​ offers an extensive selection ofย optical filter setsย andย filter accessories, as well as custom solutions tailored to customer-specific needs.

Theย Thin Film Polarizer (TFP)ย separates the s- and p-polarization components. They are designed for use in high energy laser applications. Due to a high damage threshold, TFPs are used as an alternative to Glan​​ laser polarizers or Polarizing beamsplitter​​ cubes.

TFPs are widely used in liquid crystal display (LCD) screens and optical communication due to their superior polarization properties.

CRYSTECH Inc.ย is a global supplier of Alexandrite, KTP, GTR-KTP, RTP and KDP Q-Switch, Nd:YAG and CTH:YAG crystals, thin film polarizers, laser optics and more. The company has become one of the leading manufacturers of KTP crystal and laser components in the world. CRYSTECH has multiple​​ product linesย and workshops for crystal growth, orienting, dicing, polishing, and coating.

Infrared (IR) sensing is now widely used in motion detection, machine vision, industrial automation, agriculture, and medical applications as it enables the visualization of complementary information to visible imaging approaches. For example, infrared machine vision applications can be used for fault inspection in photovoltaics and quality control in manufacturing.

A​​ blog post​​ explores​​ what IR radiation is, how IR sensing works and the typical optical components used, and an outlook on how​​ Iridian Spectral Technologiesโ€™ product range can help you with your IR sensing applications:

Often,ย Chroma Technologyโ€™s AT filter sets are a lower cost option than their ET filter sets.

AT filter sets are the perfect choice for routine fluorescence detection and assays, as well as for most applications requiring accurate color discrimination and excellent out-of-band blocking. ET filter sets are Chromaโ€™s highest quality option. They have zero-pixel-shift image registration, and are necessary for applications requiring the highest possible signal intensities.

Chroma offers an extensive selection ofย optical filter setsย andย filter accessories, as well as custom solutions tailored to customer-specific needs.

Waveplatesย (retardation plates or phase shifters) are made of materials which exhibit birefringence. The velocities of the extraordinary and ordinary rays through the birefringent materials vary inversely with their refractive indices. The difference in velocities gives rise to a phase difference when the two beams recombine. At any specific wavelength the phase difference is governed by the thickness of the retarder.

Superlum Diodesย presents their newest product:ย BLL Ultra-Compact Broadband Light Sources. These devices are wide spectrum SM- or PM-fiber-coupled light source modules for applications requiring a reliable, powerful, stable, and low-noise SLD light source with a broad and flat spectrum, as well as a short coherence length.​​ 

A high-precision current and temperature controller powers the SLD module inside the light source. The SLD output can be modulated (ON/OFF) at the rate of up to 10 kHz. This BLL light source is designed to be mounted on a PCB or a Superlum BLL Evaluation Board. This optional BLL Evaluation Board enables quick and easy BLL light source setup and testing.

โ‚Security

Quantum random number generators are widely used as a source of unpredictable randomness in applications beyond cryptography. Sectors as diverse as finance, automotive, gaming, and telecommunications are already leveraging QRNG to strengthen security.ย ID Quantiqueโ€™s (IDQ)​​ ownย QRNG chipsย are already established as the go-to technology for mobile and IoT applications. Recently they have also been used to secure orbital satellite communications, proving their suitability for use in even the harshest of environments.
