Oct 19, 2011 With ray deviation of 90°, TECHSPEC® Broadband Anti-Reflection (BBAR) Coated Right Angle Prisms are suited for use with low-power laser sources. Products are most often used to bend image paths or redirect light at 90° angle but may also be used in combination for image and beam displacement applications. Featuring tight tolerances and precision N-BK7 substrate, prisms come in 5-50 mm sizes and with coatings for 425-675 nm, 400-870 nm, or 600-1,050 nm to meet specific application needs.

Aug 17, 2010 Used for wavelength-separation applications, Infrared Equilateral Prisms with Calcium Fluoride substrate feature 1.434 index and transmission properties from 350 nm to 7 µm. Germanium versions are suitable for applications in 3-12 µm region where optical path length needs to be maximized. With transmission from 1-16 µm, prisms with Zinc Selenide substrate are commonly used with CO2 laser applications. Total beam deviation and wavelength separation is dependent on refractive index.

Jul 17, 2009 Used with well-collimated light sources, IR Right Angle Prisms utilize total internal reflection for right angle path bend. They are available with Calcium Fluoride substrate, which has refraction of 1.434 and provides transmission from 190 nm to 7 µm, in 12.7, 25.4, and 38.1 mm sizes. Prisms are also available with Germanium, suited for applications in 3-12 µm region, and Zinc Selenide with transmission from 1-16 µm. Germanium/Zinc Selenide units are available in 12.7 and 25.4 mm sizes.

Mar 26, 2008 Made from material with coefficient of thermal expansion of 0.5 mm/°C, UV Fused Silica Corner Cube Retroreflector offers transmission in UV, visible, and near-IR. When any laser beam hits corner cube, it reflects back in direction that it came, irrespective of what angle it arrived at. Available in 4 sizes ranging from 7.16 mm to slightly more than 50 mm in dia with larger sizes offering 3 arc-sec beam deviation, unit comes with or without aluminum coating.

Aug 11, 2003 Hollow, penta prisms employ 2 coated, mirrored surfaces oriented at 45° to redirect incoming light 90° without inverting or reversing image. Products are available with visible (Enhanced Aluminum) or IR (Protected Gold) coatings. Beam deviations of 30, 10, or 5 arc seconds are available in 12.7 and 25.4 mm clear apertures. Accuracy of existing wavefront varies from 0.25-1 wave (depending on the model chosen), and mirrors are mounted in integratable package.

Jun 03, 2003 Circular Differential Interference Contrast (C-DIC) prism uses circularly polarized light in contrast to conventional DIC to solve insufficient contrast problems observed in classical brightfield and darkfield microscopy. It allows fine surface structures to be observed with high contrast and resolution simultaneously, independent of orientation. Product is inserted into compensator mount of microscope and is used with 2 sliders. No stage or object rotation is required.
