captured, allowing for spatial angular relationships, wedge orientations and pyramidal angles to be measured. Laser Components has experience in the manufacture and specialist coating of laser optics, including optical prisms. Its Isosceles
Among the prisms on the market today include the PrismMaster Flex from Trioptics, a versatile goniometer for optics manufacturing. The vertical configuration and modular product concept make it a productive yet flexible solution for production-related quality testing of prisms and plano- optical components. The goniometer enables optimal adaptation to customers’ measurement requirements by means of three expansion stages. With an electronic autocollimator in a swivel arm, the PrismMaster Flex is well-suited for productive measurement of surface angles of manufactured prisms in comparison to a known reference prism. With measurement times under one second per sample, the system delivers rapid results. In the PrismMaster Flex 1D,
the position information of the swivel arm is captured so that absolute surface angles and tilt angles are also measurable. In the PrismMaster Flex 2D, the position information of the sample table is additionally

Brewster prisms are used primarily in beam deflection and compensation of GVDs (group velocity dispersion) in femtosecond laser applications. In such a setup the prism
would be placed in the beam path such that the beam is incident on the leg face of the prism at the Brewster angle. In this instance, light that is polarised parallel to the surface is transmitted with negligible loss, and light that is polarised perpendicular to the surface is predominantly reflected. Isosceles Brewster prisms are typically supplied un-coated. Laser Components

Edmund Optics is a world- class manufacturer of stock and custom optical prisms. The company produces more than 500,000 prisms per year from a wide variety of Schott, Ohara and CDGM substrates. Its factories utilise a full range of precision manufacturing equipment for grinding, polishing and fine-finishing, all supported by a comprehensive suite of metrology. These capabilities allow highly- skilled technicians to hit high precision specifications such as λ/20 irregularity, 0.5 arc- second angular tolerances and 10-5 surface quality.
in a range of standard sizes. As with the majority of the company’s manufactured products, custom designs are available.
The PZX prism grinding machine from OptiPro is the latest solution for companies looking to enhance their prism manufacturing capabilities. The PZX is capable of machining prisms up to 6 inches thick with a maximum diameter of 10 inches for the longest diagonal. Powered by user-friendly G series software, operators can quickly set up jobs to machine all prisms surfaces in one cycle by specifying the angle
and material removal for each surface. Compound angles can be machined with precision due to a rotating B-axis with -90 to 180 degrees of motion. In addition, dual spindles provide the ability to perform rough and fine grinding of prism surfaces in one cycle without the need to manually change tools. EO

manufacturing facilities are complemented by a vast inventory of standard components that can be quickly modified for rapid prototyping. Where a fully custom prism is required, expert optical design and manufacturing engineers can help develop a solution. All prisms are available with a wide range of anti-reflective coatings on the entrance and exit faces, as well as metallic coatings for reflective surfaces if needed.
