Advantages of PPC's Ion-Beam-Sputtered (IBS) Dielectric Thin Films
--------------------------------------------------------------------------------
Durable, dielectric thin films are easy to clean and chemically resistant
Dense, non-porous structure is insensitive to moisture
Low scatter and absorption losses result in high-damage thresholds
Repeatable, highly controlled process for precise layer control
--------------------------------------------------------------------------------
At PPC, we use ion-beam sputtering (IBS) technology because IBS is a repeatable and controllable process that results in dense, durable, high-damage-threshold thin films. Since the materials are directly sputtered onto the substrate, the process can be precisely controlled and easily automated so that films can be deposited with extremely high accuracy and repeatability.
Unlike conventional evaporative and ion-assisted films that have porous microstructures, IBS films have extremely densely packed structures that make them impervious to water vapor, resulting in an insensitivity to changes in heat and humidity, even in a vacuum environment.
Types of coatings that PPC does every day on standard or customer-supplied substrates:
High reflectors
Anti-reflection (ARs)
Beamsplitters
Polarizers
Partial reflectors
Dichroic mirrors
Non-polarizers
Low dispersion
Broadband dielectric

OptoSigma supplies a wide selection of optical thin film coatings. These coatings are often provided as part of the optical component but they may also be ordered separately to be applied to an uncoated element. For example, it is possible to apply an Anti-Reflection coating to any uncoated lenses, windows or optical fibers. Also reflecting coatings may be applied to uncoated substrates to form mirrors or partial reflectors. To make this process simple we have listed some of our most common standard coatings. To order you simply append the coating suffix to the base part number and specify the surfaces to be coated. If you don't find the exact coating you need please ask us to provide you with a custom solution. Our coating engineers will use the latest design software and production techniques to provide you with the coating you require.

Windows are frequently used in optical systems to separate the environment in one part of the system from another, such as to seal vacuum or high-pressure cells. Because the infrared transmitting material has a high index of refraction, an anti-reflection coating is typically applied to windows to minimize losses due to reflections.

Thin film coating is a vacuum deposition procedure used to enhance the transmissive properties of an optical surface. The most common types of dielectric coatings are anti-reflection and high reflection coatings, but beam-splitter, band pass filter, edge filter, and polarizing coatings are also available. Because thin film coatings are more durable than optical glass, coatings also help protect an optic surface from scratches and the environment.
Optimax produces optics up to 300mm in diameter with a wide variety of narrow and broadband anti-reflection coatings including doublet interface coatings. Both metal and dielectric mirror coatings are also available. For custom coatings, we utilize TFCalc thin film design software. Please see the reverse side for sample reflectance curves.
Optimax performs test runs of all coatings before beginning production to ensure a good design. We use a Perkin-Elmer Lambda 900 Spectrophotometer to check the performance of the coating upon completion. Adhesion, abrasion, and humidity tests are available to verify coating durability in accordance with sections of MIL-C-675C, MIL-C-48497A, and MIL-C-13508C specifications. Laser damage testing is also available upon customer request.

Windows are used to enable optical radiation to pass from one environment to another without allowing the environments to mix.
Optical flats are used with monochromatic light sources, such as sodium lamps, to evaluate surfaces of other optical elements.

Opal glass is a superior diffuser to ground glass because it depends upon the scattering of light by particulate matter suspended in the glass itself rather than a surface reaction. It is correspondingly less efficient in overall transmission.

Windows are used to isolate different physical environments while allowing light to pass. The selection of a window should consider the properties of the different optical materials, transmission, wavelength range, and resistance to the environment. Tower offers a wide range of different materials and a variety of anti-reflecting coatings that can be deposited on the windows.
Tower Optical manufactures windows from BK7, UV Grade Fused Silica and Sapphire. Other materials are available on a custom basis. In addition, we offer three different quality standards as described below. Contact factory for info on Sapphire Windows.
Mirrors are smooth, and contain a highly polished surface for reflecting light. The reflecting surface is usually a thin coating of aluminum or silver. Most mirrors for optical applications are called front surface types since the coating is on the front surface thereby eliminating the optical properties of the glass from affecting the incident or reflected light. The rear surface is usually fine ground. All of the following mirrors have a protected Aluminum coating applied to the front surface.

The windows are designed to be used in precision optical systems. The optical transmission is high with little or no distortion of the transmitted signal.
* Windows - Zinc Selenide (no Ar)
* Windows - BK-7
* Windows - Fused Silica
* Windows - Germanium
* Windows - Heated
* Windows - Sapphire
* Windows - Silicon
* Windows - Zinc Sulfide

Among the many diverse custom optical coatings, components
and assemblies that PPC offers are diode-pumped Nd:YAG
resonator mirrors, 50/50 non-polarizing beamsplitters, laser mirrors
and thin-film polarizing beamsplitters.
For all the optical components we
provide, we use only ion-beam-sputtered
(IBS) coatings because our IBS coatings are
significantly more dense, durable, and rugged
than conventional coatings. The IBS coating
process is both accurate and repeatable, resulting
in precision coatings that are easy to
clean, chemically resistant and insensitive to
moisture and other environmental factors.
These are just some of the types of coatings that PPC
does every day on in-house and customer-supplied substrates.
High-energy ion-beam-sputtered thin films that are
accurate, durable and environmentally stable are our forté,
and we can turn around parts in as little as 48 hours!

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.
|
|
|
These five sided prisms are used to deviate the incident beam 90° independent of small positional changes of the prism relative to the beam. The image is neither inverted nor reverted. Reflecting faces are AlSiO coated.

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.
