When a short pulse travels through a dispersive medium, the component frequencies are separated in time. Sill Optics provides beam achromatic expanders and f-theta objectives to account for this.
Lenses and optics
Edmund Optics has improved its Tech Spec line of achromatic lenses. They are now offered with the VIS 0Â° multilayer, broadband anti-reflection coating to minimise reflections in the visible spectrum.
Edmund Optics has introduced a precision-grade cube beamsplitter for high-power Nd:YAG Lasers. Tech Spec High-Energy Polarising Cube Beamsplitters use multilayer dielectric film technology to minimise reflection and absorption losses.
Aspheric lenses offer optical designers control of light-ray refraction over the whole lens surface, making it possible to produce optical systems with higher performance in compact packages.
B&M is now offering customers sample cases of optical lenses. Three different types are available, including ground and polished optics and moulded lenses of various shapes.
Edmund Optics has introduced its new ReflX 15X Objectives, which exhibits near-diffraction limited performance. It is used in applications requiring superior image quality over a broad spectral range.
Edmundâ€™s family of beam expanders offers high performance optical designs packaged in a precise opto-mechanical platform, with smooth movement for the optics and a precise focusing mechanism.
Laser Components has introduced 3rd Millennium filters, which combine patent-pending, hermetically-sealed assemblies with Omega Optical Alpha technology.. They offer superior spectral performance and longer filter life.
Edmund Optics introduces new EO designed and manufactured large format lenses specifically for line scan and area scan cameras. They are compatible with 12k pixel cameras.
Edmund Opticsâ€™ has released a new series of lenses that exhibit near-diffraction limited performance for applications requiring superior image quality or focusing performance over a broad spectral range.
