PPC provides high-quality custom optics and optical assemblies which
utilize our IBS coatings, ultraprecise fabrication capabilities and epoxy-free,
bonding technology—Chemically Activated Direct Bonding™ (CADB). They
are available in a wide variety of materials including fused silica, BK7, Zerodur®, LaSFN9, YAG, ULE, and other optical glasses and crystals, and can operate over wavelength ranges from 250–2200 nm.
These assemblies are ideal for increasing the sensitivity in beam-delivery microsystems, fiber-optic, and endoscopic systems used in fluorescence spectroscopy, Raman spectroscopy, optical-coherence tomography (OCT), multiphoton microscopy (MPM) and confocal microscopy. Because of their miniature size, they can be placed right at the objective lens or at the tip of optical fibers and light pipes.
Whether you need 1 or 10,000 pieces, our precision wafer-based processes result in high yields and competitive costs, especially at higher volumes. The high-precision assemblies have been widely used for beam steering, wavelength locking and reference cavities in telecommunications and metrology.
Call us to discuss your custom prism or micro-optics needs.

Equilateral prisms are normally used for the dispersion of light into its different colors. Light incident at an oblique angle to the first face is dispersed according to its wavelength and emerges as a spectrum from the opposite face. We offer these prisms made from BK7 optical glass.

4 types of coupling prisms are available; right angle, isoceles, doubles and cylindricals.
Their index of refraction must be higher than the refractive index of the waveguiding material. They are made from ordinary high index glasses like SFL57 from Schott or S-TIH53 from OHARA, with a refractive index well over 1.8 in the visible range of optical spectrum. These are standard glasses and we will gladly provide all the information on this glass if needed. In m-line spectroscopy, the exact value of the base angle is important and it is specified for each prism. The prism can be provided alone or glued to stainless steel holder that can be easily attached to the coupling clip.

Prisms are blocks of optical material with flat, polished sides that are attached at precisely controlled angles to each other. Prisms may be used in an optical system to deflect or deviate a beam of light. They can invert or rotate an image, disperse light into its component wavelengths, and be used to separate states of polarization.
The orientation of prism determines its effect on a beam of light or image. A viewer looks through a prism at an object and sees a virtual image. This image may be displaced from the original object, or, in the case of a dove prism, may coincide with the object. Furthermore, image orientation may differ from the object, as shown in the drawings below.
Prisms will introduce aberrations when used with convergent or divergent beams of light. Using prisms with collimated or nearly collimated light will help minimize aberrations. Conjugate distances that include prisms should be long.

A prism is a complex optical component with at least two plano surfaces separated by a wedge angle. Prisms are used to reflect or refract a beam of light. Our manufacturing capabilities include right angle, dove, penta, pechan, and wedge prisms as well as cubes, windows, precision flats, beam splitters, and mirrors. These components are found in dual channel instruments, anamorphic systems, imaging systems, and similar applications.
Optimax has interferometers, autocollimators, and a Wild Goniometer for precision measurement of flatness and angles. We also make transmission flats for interferometric testing of surface irregularity to 50th wave.
Optimax inspects 100% of all optics and provides test data with prototype orders. We utilize state-of-the-art metrology and provide on-time delivery guarantees to ensure your satisfaction!
Optimax can provide optics complete with BBAR, V-coat, and mirror coatings. We have four electron-beam coaters supported by a Perkin-Elmer Lambda 900 Spectrophotometer. For more details please see our Coatings data sheet.

Right-angle prism is the most common type of prisms. It is used to re-direct a beam of light at 90 degrees from the the incident direction or used as a 180 beam retro-reflector. They are often coated with various optical coatings to form cubic beam splitters and color separation cubes used in various projection systems.
High transmission can be achieved, using the hypotenuse face in total internal reflection (TIR), with an antireflection coating on the entrance and exit faces.
The prism can be used as an internal or external mirror by applying a metallic coating on the hypotenuse.
We also offer fused silica prisms, and precision grade and ultra-precision grade glass prisms with tighter manufacturing tolerances.

Prisms are transparent optical blocks having at least two flat polished sides inclined relative to each other, at precisely controlled angles, so as to deflect, deviate, and rotate beams of light as well as dispersing their wavelengths.
There are many types of prisms, each having a particular shape to achieve the necessary reflections to perform a specific optical task.
Tower Optical’s prism capability includes Penta Prisms, Right Angle Prisms, Dove Prisms Roof Prisms, Corner Cube Reflectors, Anamorphic Prisms, Wedge Prisms and Polarizers called Glan-Taylor Prisms, Wollaston Prisms and Rochon Prisms.
For right angle prisms Tower offers three different quality standards, .Common Grade, High Grade and Laser Grade.
These prisms are also available in UV grade Fused Silica as well as other material. Optical coatings are also available for AR, Mirror or beamsplitter applications.
