Request InfoSill OpticsSill Optics GmbH & Co. KG has released four standard models of f-Theta objectives for 405-nm printing applications, particularly for the process of transferring digital data from computers directly onto plates. The objectives produce diffraction-limited spots over the entire scan area for high-resolution results, and they offer laser beam diameters of up to 14 mm and exposure lengths of ≥600 mm. Antireflection coating makes them suitable for use in the 400- to 410-nm range, and other wavelengths are possible upon request. The laser optics are made of highly transmissive glass, with...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 2/13/2023Swept Tunable LaserThe Laser 2000 series swept tunable laser from Quantifi Photonics Ltd. is a compact, laboratory-grade device that can be operated as a step-tuned, swept-wavelength, or fixed-wavelength...Photonics.com 3/29/2024Lidar & Optical Sensing LaserThe Model 1786 from Ortel is a 1550-nm laser module made for use as a continuous wavelength coherent optical source for optical sensing and lidar systems.
