Transcription

1 The LINOS Plano Optics LINOS is known for high-quality plane plates from optical glass, fused silica and sapphire, as well as a variety of prisms, filters, beam splitters, reticles and dispersion plates. We can offer support for all your applications that require precise planarity and flawless surfaces. High-quality materials ensure the best possible transmission and consistent, reliable quality standards in all LINOS products. In production, we place a high value on the narrowest possible angular tolerances and the best parallelism, integrity and fit. LINOS plano optics and their coatings are manufactured using the latest machines and are subject to constant, meticulous quality control. LINOS stands for lasting precision! Our quality criteria: High-quality glass materials from established manufacturers Many years of experience in precision optics production The narrowest possible production tolerances! Special features: Many components are available in mounts compatible with LINOS bench systems. Prisms can also be found in the Prism Wizard of the WinLens 3D program. Ideal areas of application: Beam deflection, beam splitting, measurement tasks, view panels, and more. 494
