Small Glass Optics enhance Chips on Board capabilities.

January 29, 2015

Designed to handle Type I–V lighting distribution fixtures, small optic prisms are intended for use with Chips on Board (COBs) and can help improve direction of light. These products, available as various forms of convex lenses and sophisticated prisms, exhibit increased tolerance for interior heat created by COB and feature dimensions that help decrease fixture size.

Dispersion Prisms suit laser cavities and spectrographs.

August 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.

June 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. Read More

Wedge Prisms can correct elliptical shape of diode outputs.

October 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. Read More

Right Angle Prisms have transmission-optimizing coating.

October 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. Read More

IR Equilateral Prisms are offered with 3 substrate options.

August 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.
