No matter whether your application is holography, interferometryย or directย lithographyย โ€” theย SLM​​ 355ย fromย Xiton Photonicsย might be the best choice! Thisย laserย system offers the highest average output power atย 355 nmย in combination with a long coherence length of several meters! In numbers: 2.0 W at 355 nm with 5.0 meters coherence length.

Theย SLM seriesย features the following wavelengths: 213, 266, 355, 532, and 1064 nm.

Theย IDOLย 671-447 isย Xiton Photonicโ€™s top selling product for Flat Panel Display (FPD) repair.

Highย laserย power densities atย 671 nmย (red) andย 447 nmย (blue), based on the fundamental wavelength 1342nm, can be used to carbonize​​ Everbright pixel errors selectively. The system grants long life times in continuous 24/7 industrial use.

Each laser delivers < 13 ns short pulses with a superior beam quality. Due to high pulse-to-pulse stability of ฯƒ < 2% and a sealed housing, the IDOL series is perfectly suited for continuous 24/7 industrial use.

CNI Optoelectronics Techย (CNI)ย ย launchedย an easy-to-operateย Hg-light wavelength calibration light sourceย for wavelength and spectral line calibration of spectroscopic equipment. The spectral range is from 253 to 1700 nm in the UV-visible band. The easily identifiable mercury and argon transmission spectral lines are printed on the housing for fast and reliable wavelength calibration.

The wavelength of a fiber optic spectrometer will shift slightly over time and due to changes in the environment. If wavelength accuracy is important to your application, consider choosing an Hg-light wavelength calibration light source to periodically adjust the wavelength of the spectrometer.

The 532-nm single frequency emission of theย SLM 532ย laser fromย Xiton Photonicsย is the well suited choice for High Spectral Resolution LiDAR (HSLR),​​ based on iodine-absorption filters.

This special LiDAR method enables the detailed quantification of molecular backscattering of aerosols in the atmosphere. It can be a valued building block for improved weather and climate models.

Chroma Technologyย producesย Machine Vision, thin-film interference filters, with extremely durable sputtered coatings in various form factors and sizes that work in a variety of applications.

These optical filters for automated vision applications, such as machine vision and robotic guidance, can provide greater contrast over a wide range of viewing angles by detecting the signal you need and reducing the noise you donโ€™t. Chroma also offers affordable custom solutions so you can manage light your way.

Diffractive optical elements (DOEs) are the way to get better results in picosecond laser skin treatment according to a recent article, entitledย โ€œDiffractive micro-lens array (DLA) for uniform and selective picosecond laser treatment.โ€

The researchersย found that compared to a regular micro-lens array,ย diffractive beam splitters​​ and​​ diffractive lens arraysย provide better uniformity and penetration of the skin. The excellent spot uniformity created byย Holo/Orโ€™sย MSย diffractive beam splitters allows for faster healing and better results of skin fractional treatments.

Spectral emission lines are unique sets of spectral lines that serve as the fingerprints of chemical and molecular species. These lines occur when atoms or molecules transition from higher to lower energy states, emitting specific wavelengths of light in the process.

Iridian Spectral Technologiesย offers a range ofย bandpass filtersย andย edge filtersย in various wavelength regions, including visible, near-IR (NIR), mid-wave IR, and long-wave IR (LWIR). Their newย custom filtersย in the 10โ€“15 ยตm range cater to specific requirements​​ for detecting​​ spectral emission lines.

Shortwave infrared (SWIR) wavelengths can be used to investigate the homogeneity of pharmaceuticals​​ or​​ the volume of a substance in a visibly opaque package.​​ SWIR imaging can also be used to detect minute differences in a surface that are undetectable using visible wavelengths or pierce through dense atmospheric conditions to detect​​ undiscovered​​ structures from the air or space.

Chroma Technologyย produces numerousย filters to work throughout the range of SWIR wavelengths, while blocking unwanted signals.

Aย Thin Film Polarizer (TFP)ย is a versatile optical component that finds application in various fields.

By separating polarizations, TFPs​​ help to reduce signal loss in long fibers and increase the bandwidth of signals transmitted.

TFPs​​ are widely used in LCD screens to enhance their brightness, contrast, and color accuracy.

In biomedical imaging, it is possible to selectively highlight certain structures or tissue types in an image.

TFPs are also widely used in analytical instrumentation, particularly in polarimetry and ellipsometry.

CRYSTECH Inc.ย is a global supplier of Alexandrite, KTP, GTR-KTP, RTP and KDP Q-Switch, Nd:YAG and CTH:YAG crystals,​​ TFPs, laser optics and more.
