Get Quality Polarizing Coatings for Broad-Band
customcoatings

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
camerafilter

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
standardcoatings

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 »»

How Optical Coating Helps Enhancing Optical Performance
Optical Coatings

Optical coatings have industrial, biomedical and military applications. When thin film coatings are applied on different surfaces, they help to enhance optical performance of the entire system. The thin film layers applied on the surface create interference effects which either enhances transmission or reflection properties in the optical system. There are various factors that will determine the performance of an optical coating. For a start, the number of layers applied on »»

Different Types of Optical Coatings and Benefits
special optical

Optical devices such as mirrors and lenses need to be coated in order to alter the way light interacts with them. The type of coating applied will depend on the application and how it will benefit the system. In most cases, these coatings allow the device to perform better by transmitting or reflecting light in the right way. They simply enhance the device’s properties. Anti-reflective optical coatings This is applied on the surface of lenses or other optical elements in »»

When light passes through a material like glass, part of it is transmitted whereas the rest is reflected. Metal coatings are added in order to alter the transmission or reflection of light. Coatings help to absorb a certain level of light in order to enhance clarity and performance of the optical system. The surface where light is being transmitted (dielectric surface) and the metal coating will have varying levels of height and thickness. Therefore, light incident on a metal »»
