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 »»

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 »»

How to Model the Optical Properties of Rough Surfaces

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 »»

5 Tips for Cleaning Your Optics with a Clear Conscience

Optics are very sensitive to dust and other dirt particles. The dust and stains can result to scattering while some of the dirt can damage the optical coatings. This leads to decreased performance and even loss of the optics which are usually costly.The method of cleaning is crucial to whether you get back optimum performance or you cause further damage. Optics are very delicate and sensitive such that even mere rubbing of their surface with handkerchief can result in damage. »»

Technical Facts About Hydrophobic Glass and Its Coating

Hydrophobic glass is a type of self-cleaning glass coating that is designed to keep the surface dry and free of dirt. The nanoscopic surface layer works by repelling water. Any water droplets that hit the surface coated with hydrophobic glass will be rolled up so that they don’t cling onto the glass. One of the common uses of hydrophobic coatings is on the car’s windshield. Vehicle windshields need this type of glass so that rain droplets do not affect the driver’s visi »»

Differences and Similarities between Cylinder and Spherical Lens Fabrication
special optical

                  The production methods used in cylinder and spherical lenses differ greatly. Even though both lenses share some similarities in terms of their circular design, the fabrication process is never the same. There are certain aspects of the production stages such as grinding and polishing where the same techniques will be employed when dealing with both types of lenses. However, there are som »»
