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, polycarbonate cannot resist scratching and that’s why most optical coatings are treated further to enhance their durability. The coatings undergo thorough treatment to ensure that they are resistant to abrasion. Infrared (IR) optical coatings are also made using high index plastics. Other materials can be used to enhance the durability and resilience of the optical coatings.
Optical coatings are basically used to enhance visual outcomes for those people who wear eyeglasses. For instance, the coatings can be used to protect the lens material and the patient’s eye. Coatings are also important because they can help to reduce eyestrain and fatigue especially for those people who stare at the computer for extended periods. Coatings are used to help people who have a poor vision when driving at night.
The roles of optical coatings continue to increase over the years and that may explain why many companies are now manufacturing these products. One of the things that you must always remember when shopping for IR optical coatings is that quality is key. The way the coatings have been produced, the equipment and procedures followed throughout the manufacturing process will determine the quality of the resulting optical coatings. It is always important to find out if the lab which produces the optics offers products which are up to standard.
One of the features to consider when shopping for optical coatings is whether they are scratch resistant. Coatings that are designed to prevent any scratching do not penetrate on the lens material so they shouldn’t alter the material. Quality coatings are designed to resist minor abrasions. However, the user needs to exercise caution and avoid cleaning the lenses regularly because it may end up removing the coating. Most manufacturers offer polycarbonate lenses which are already coated in order to prevent scratching.
Optical coatings should have an anti reflective property. This prevents light from being reflected by the lenses and causing strain and fatigue. The anti reflective coatings will minimize these reflections and improve the transmission of light through the lens. These coatings are manufactured by applying thin film coating layers on both lens surfaces in order to cancel the reflected light.
Coatings with an anti-reflective property are used for their cosmetic benefits as well as to reduce glare and improve clarity when driving at night. Regardless of the types of coating you opt for, make sure you are getting products of high quality. Look for a manufacturer who offers optical coatings of different types. If you are looking for bulk IR optical coatings,please contact the manufacturer can offer them at a reasonable rate.
