Improving Focusing Quality of Spherical Lenses
Standard Coatingsbanner

Lenses are different from other transparent objects because of their ability to focus light. There are many types of lenses and the spherical lens is one of them. The spherical lens is a lens whose surface is the shape of part of a cylinder or sphere. The unique quality about this lens is that it does not bring parallel rays of light to a common focus but rather the focus depends on the distance from the center of the lens and the rays that pass through the edges of the lens »»

The Importance of Designing For Optical Assembly
Custom Coatingsbanner

Optical design is the process of design optical devices to meet a set of performance constraints and requirements, including manufacturing and cost limitations. The process involves determining such parameters as surface profile types (diffractive, holographic, aspheric, spherical, and so on), the radius of curvature, material type, decenter (translation in X and Y), angular motion (tip/tilt), axial motion (translation in Z), and distance to next surface. There are several re »»

Technical Facts about Hydrophobic Glass and Its Coating
Ir optical coatings

Hydro is Greek for water while phobos means fear. The surface of a material can react either in a water-loving (hydrophilic) or water-hating (hydrophobic) manner. Hydrophobic glass has many applications. In eyewear, water resistance is achieved through a transparent titania (titanium dioxide) coating of between 20 and 30 nanometer. Hydrophobic coating is also found in nature in the wings of many insects and on some leaves.  Other than eyewear, hydrophobicity concepts a »»

The Importance of Designing for Optical Assembly
IR optical coatings

Many manufacturers pay the most attention to optical assembly without giving the design process much consideration. If the design is treated as an afterthought, assembly can become a difficult and time-consuming process. Paying a little more attention to the design can be a huge cost-saver. This is because it ensures the optics are perfectly designed before going into production. We’ll look at the most important considerations as you develop optics and why you need to avo »»

Advantages of Hydrophobic Glass and its Coating
Hydrophobic Glass Coating

Over the past few years, there has been an increase in the use of hydrophobic glass. Popularly known as self-cleaning glass, many companies have adopted hydrophobic glass due to its many fascinating benefits. Not very long ago, scientists realized that a glass with hydrophobic coating has more usefulness and durability than the normal glass. Since this discovery, many manufacturers have adopted hydrophobic glass to make better gadgets, car windows, house windows etc. This is »»

Differences and Similarities between Cylinder and Spherical Lens Fabrication
Standard Coatingsbanner

You must have realized that both spherical and cylindrical optics have a circular profile when viewed end-on. However, there is a common misconception that similar production methods apply to the two optics. The methods used in the fabrication process of these optics use a similar concept of grinding and polishing, but these methods aren’t entirely similar. These optics have different aspects, respond differently to various levels of pressure, stress, and more. Here is what »»

Cleaning Optical Mirrors vs. Lenses – Key Differences
chirpedmirrors

Optical mirrors and lenses can get contaminated in many ways. The contamination can be minimized by returning the optics to their cases after use. Covering them for protection from the outside environment can also keep them clean for longer. Unfortunately, even with all these precautions, these items will eventually accumulate stains, dust, and other forms of contamination. The most recommended procedures for cleaning both optical mirrors and lenses are largely same. The fir »»

Quality IR Optical Coatings
Ir optical coatings

IR optical coatings (IR for infrared) are used in many high end applications. They are used to make optical materials which are suited for patient’s needs. Lens coatings need to be created to resist damage. Most optical coatings are made using polycarbonate in order to prevent shatter upon impact. Polycarbonate is mainly used in the manufacturing of optical coatings because it is lighter in weight. It can be used to make lenses of superior optical quality. However, pol »»
