Request InfoUmicore Electro-Optic MaterialsUmicore Electro-Optic Materials has announced two manual-focus lenses to its range of products. The 75-mm MFX f/1.1, with a barrel focus ring, and the 100-mm TFX f/1.0, with a focus knob for convenient focusing action, join the already offered 50-mm MFX lens. Manual-focus lenses are suitable for systems where the user wants to achieve the sharpest image possible, whether the object is close or far away. The lenses feature an anodized finish with smooth and positive focusing action, interfacing to the camera body with an M34 × 0.5 fitting. Typical applications include...See full productRelated content from Photonics MediaPRODUCTSEuroPhotonics Spring 2021 IssuePyroelectric SensorsThe ezPyro™ SMD+ series of pyroelectric sensors from Pyreos provides fast and accurate detection in a small, low-cost, integrated subsystem to a wider range of anesthetic, refrigerant, and...EuroPhotonics Winter 2020 IssuePhotolithography SystemsThe PhableX™ line of photolithography systems from Eulitha AG is designed for the high-volume production of photonic products.

Enter Class 1 laser products — lasers that are so safe that the user doesn’t require specific laser safety training or protective eyewear. Some precautions still exist, though.When purchasing an industrial laser system, the astute buyer will look for a Class 1 laser product — a system where the laser beam hazard is completely enclosed and there is no potential laser...Photonics HandbookFluorescence Lifetime Imaging: Choosing the Best Approach: Fluorescence lifetime imaging microscopy (FLIM), which measures the spatial distribution of the fluorescence decay, can be achieved either in the time or in the frequency domain. Each approach exhibits advantages and disadvantages, depending on the type of light detector and acquisition method employed.The term fluorescence is often applied as a synonym for photoluminescence, although luminescence actually covers fluorescence and phosphorescence. Both of these terms describe the process of...Photonics HandbookIndustrial Lasers: An Introduction to Process Qualification: The step from successfully demonstrating a new laser process on a limited number of samples under laboratory conditions, to scaling that process up for high-volume industrial use is a big one. In particular, it’s necessary to determine how variations in process parameters affect end results, so that acceptable process input and operating ranges can be determined.Materials processing with lasers is actually a broad term for a diverse range of applications. The major categories of these uses, and the lasers that service them, are summarized Table 1.
