Dispersion Prisms suit laser cavities and spectrographs.

Dispersion Prisms suit laser cavities and spectrographs.

Precision Glass & Optics    Santa Ana, CA 92704
Aug 26, 2013 With 30, 60, and 90° angles, Littrow Dispersion Prisms feature angular tolerance of >1 arc sec, surface quality of 10/5, surface accuracy of λ/20, and dimensional tolerances of ±.001 in. Uncoated models are suited for image dispersion because they can disperse white light into spectral components. Featuring anti-reflective coating on surface opposite 60° angle to provide constant deviation prism, coated models are suited for applications where it is critical to limit lasing to specific wavelength.

Plano-Concave Axicons suit laser material processing.

Edmund Optics    Barrington, NJ 08007
Jun 17, 2013 Featuring one concave conical surface and one plano surface, Plano-Concave Axicons are used in laser material processing to create ring-shaped image along optical axis and non-diffractive approximation of Bessel beam. Units are available in twelve 25.4 mm diameter models with apex angles of 90, 130, 140, 160, 170, or 175°, and either VIS 0° or NIR I coating. When Plano-Concave Axicons are used with Plano-Convex Axicons, diameter of Bessel beam can be controlled by separation between two Axicons.

Oct 26, 2011 TECHSPEC® Fused Silica Wedge Prisms offer 1/10 wave surface accuracy and 20-10 scratch-dig. Coefficient of thermal expansion and transmittance capability optimize performance from UV to NIR range. Used individually, prisms can deviate laser beam by specific angle. In pairs, prisms suit variety of beam steering applications. Versions are available, uncoated, in 0.5°, 1.0°, 1.5°, 2.0°, 2.5°, 4.0°, and 5.0° beam deviations. N-BK7 versions are also available.

Right Angle Prisms have transmission-optimizing coating.

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.

IR Equilateral Prisms are offered with 3 substrate options.

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.

Uncoated Prisms achieve 90° light path bend.

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.

Retroreflector is designed to aid precision alignment.

Edmund Optics    Barrington, NJ 08007
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.

Right Angle Prism features thermally stable design.

Edmund Optics    Barrington, NJ 08007
Oct 30, 2007 Techspec(TM) UV Fused Silica five sided penta prisms shorten optical path lengths by reflect light rays through two reflections through 90° angle without inverting or reverting images. UV grade fused silica composition offers thermal expansion coefficient of 0.5 µ/°C. Features include various coating options such as aluminized, inconel, and black paint, as well as uncoated or UV-AR coated exit faces.

Hollow Penta Prisms offer short optical path lengths.

Edmund Optics    Barrington, NJ 08007
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.

Prism ensures homogeneous illumination of specimen.

Zeiss, Carl, Inc.    Thornwood, NY 10594-1920
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.

Optical Components suit ultraviolet portion of spectrum.

Edmund Optics    Barrington, NJ 08007
Mar 25, 2003 Tech Spec(TM) UV Fused Silica Right Angle Prisms in standard tolerance offers ±5 arc-min angle tolerance and ½ wave surface accuracy. High-tolerance version offers ±40 arc-sec angle tolerance and 1/10 wave surface accuracy. Tech Spec(TM) Precision UV Fused Silica Optical Windows range from 10-25 mm dia and come with or without VIS 0° Anti-Reflection coating. Tech Spec(TM) UV Fused Silica ND Filters offer optical densities from 0.3-3.0, and are spectrally flat from 200-700 nm.
