TECH FOCUS: OPTICAL PRISMS Knight Optical FEATURED PRODUCT


Knight Optical offers a versatile range of optical prisms, including customisable options tailored to your unique requirements. Prisms serve multifaceted roles, from dispersing white light into its spectral components to redirecting and manipulating light beams. Below are the typical manufacturing capabilities it provides: • Dimensions (mm): 5 to 300+ • Form Error (lambda): < 0.25 • Angular tolerance (arc minutes): < 3 • Scratch/dig: < 60/40 Its metrology lab rigorously tests each prism, ensuring precision and performance. Quality assurance measures include surface flatness and irregularity checks on its Zygo Verifire XPZ interferometer, angular tolerance assessments with its Trioptics PrismMaster, and transmission/reflection scans using its Agilent Cary 7000 Spectrophotometer. It also conducts infrared component testing with its Agilent Cary 660 FTIR spectrometer. With Knight Optical you are guaranteed to experience unparalleled


precision, quality, and innovation. Contact its UK and US teams today to explore bespoke optical solutions tailored to your specific needs. More information: www.knightoptical.com/custom/prisms/


and rhomboid prisms. These are also offered in a range of custom design. Ecoptik provides optical prisms for various applications. The company can make many different geometrical shapes, including roof prisms, tetrahedral, wedge, octagon, penta, Powell and right-angle prisms. There is also an option for custom designs. Available from Edmund


Optics is a variety of designs, substrates, and coating options. Designs include right-angle, amici, penta, schmidt, wedge, anamorphic, equilateral, dove, or rhomboid prisms, in addition to corner cube retroreflectors or light pipe homogenising rods. Anti-reflection coatings include MgF2, UV-VIS, UV-AR, VIS 0°, VIS-NIR, or multiple laser line options. FOCtek provides a range of high[1]precision prisms,

including penta prism, beamsplitter penta prism, right-angle prism, and corner cube. The micro penta prism and right[1]angle prism are most widely used in optical communications, such as optical switches. G&H produces prisms for a


wide variety of applications, from high[1]energy laser cavities to broadband imaging systems. Prism types include Abbe, Amici, Dove, Leman, penta, periscope, Porro, rhomboid, Schmidt, Wollaston, Zeiss, and others. IRD Glass manufactures custom optical prisms for applications spanning laser optics to imaging devices. Available are basic right[1] angle prisms, rhomboid prisms, wedge prisms, penta prisms, dove prisms, roof prisms and many other variations and assemblies.


Kingsview Optical can


manufacture optical prisms for a range of requirements from 0.8mm diameter micro prisms up to 100mm periscope prisms. Perkins Precision


Developments manufactures custom prisms and assemblies in numerous shapes and sizes, and in a variety of materials including fused silica, fused quartz, N-BK7, YAG, ZnSe, SF11 and other high-index glasses. Prisms are available uncoated or coated with the company’s low-loss, high- energy IBS thin film coatings for applications in the UV, visible and near-infrared (NIR). Precision Optical’s core


product is the ultra-precise prism and the company manufactures numerous shapes from standard prism shapes to more intricate custom geometries. It can produce sizes from 3mm to 300mm,


with or without custom thin film coatings, as individual components or as multi- component prism assemblies. Available from Sydor Optics


are custom optical wedges that can be used in a variety of applications. Flat optics with a wedge angle are typically used in laser applications for beam steering and beam displacement or for preventing stray-back reflections, and can also be used in optical components to change the direction of light. Prisms available from Taiyo


Optics include right-angle, penta, beamsplitter penta, corner cube reflector, porro, dove, rhomboid, brewster prism, and many more, including customised options. This is not an exhaustive list.
