What You Need to Know About Multi-Layer Optical Coatings

Optical coatings are often used to alter the physical or optical properties of various solid materials. When thin film coatings are applied on a surface, they alter the spectral reflection and transmission of optical components. Sometimes the thin film is made up of only one layer that is deposited on a specific substrate. In other cases, the thin film coating consists of many layers. These layers are put together in order to produce the desired optical filter. This is what i »»

Common Applications of Notch Filter Optical Coatings

Notch filters are simply optical filters which are designed to transmit some wavelengths and reject a portion of the spectrum. The filters are commonly used in applications whereby there is a need to reflect or reject electromagnetic radiation effectively and at the same time provide high transmission at wavelengths beyond the spectral region that is being rejected. They have dielectric coatings which is what enables the filters to reflect laser wavelengths. Notch filters ha »»

The Evolution of Beam Steering Coatings for Micro Material Processing
Beam Steering coatings

Micro Material Processing requires a lot of precision because of the small size of components and their often sensitive application (mostly dome for miniature functional components in medical devices, instruments, vehicles, systems, and machines). There is also a complex interplay of different factors to achieve the desired manufacturing function, be it the coating, cutting, drilling, marking, or scribing. The coating of these miniature components can be done using different »»

Get Quality Polarizing Coatings for Broad-Band

Polarizing coatings for broad-band can have numerous applications. The coatings are used because of the simple fact that the human eye cannot perceive polarization of light. These coatings work by selectively transmitting the light with specific polarization. Sometimes optics are used to change the polarization state and enhance the performance of the system. Plate polarizing beamsplitters These beamsplitters are designed to transmit p-polarization and reflect s-polarizatio »»

The Common Applications of Speciality Conductive Coatings

Specialty coatings, often regarded to as “smart coatings” describe a group of coatings that respond to certain mechanical, thermal and optical stimuli. These types of coatings have been widely used today in the paint and coatings industry due to their powerful properties. Coatings can be applied on eyeglasses, TV screens and other electronics to act as a protective layer and improve the effectiveness and function of the product. It is important to note that the selection »»

8 Benefits of Band Pass Custom Optical Coatings
Band pass Optical Coatings

A band pass filter is a filter that rejects frequencies that are outside the desired range and that allows designated frequencies to go through. These filters are broadly categorized into active and passive band pass filters. Active filters use transistors and ICs and use an external power source while passive filters use capacitors and inductors and do not require an external power source. Some of the major applications of band pass filters are imaging, fluorescence microsc »»

Acrylic Specialty Optical Coatings: Benefits of Acrylic and How Optical Coatings Further Enhance these Benefits
Optical coatings

Why Acrylic? Acrylic is a popular plastic that is made using acrylic acid derivatives. There are several acrylic polymer grades to choose from and they are usually used in injection and extrusion moulding manufacturing processes. The most popular type of acrylic is PMMA (Polymethyl Methacrylate acrylic) because of its favourable qualities. So, why should you consider using acrylic? Variety You get to choose between different acrylic polymer grades. The polymers can be op »»

Thin Film Dichroic Color Separation Filters For Color Splitters
Transparent Conductive Coatings

A dichroic color separation filter is made to pass light of a small range of colors while reflecting the rest. Many of the dichroic mirrors and reflectors are known for the colors that they reflect as opposed to those that they transmit. These filters produce colors in the same way as oil films on water. When light is directed on an oil film at an angle, what happens is that it reflects on the top surface of the oil as well as at the bottom surface where the oil is in contact »»

Optical Coatings for Standard and Multi spectral Imaging

Optical coatings are used on everything. From standard mirrors and bulbs to lenses and LCD displays. Thin films of material are applied to optics or optical components in order to modify the way they reflect or transmit light. Standard optical coatings are used to block certain wavelengths of light or provide a highly reflective surface. Optical coatings can also be used for multi spectral imaging. In this case, wavelengths are separated by filters or other instruments. Opti »»
