Optical coating process

In recent years new display technologies have emerged. OLED displays, TFT’s with quantum dot technology or laser projectors offer brighter and more saturated colors than possible before. To achieve consistent colors across different displays, colorimetric calibration of the displays is essential.

Coatings designed and manufactured using dielectric materials can be tailored to balance specific transmission, reflection, and beam splitting requirements in addition to durability requirements.

‘Collimating’ is the process of accurately aligning light or particles in a parallel fashion. For light measurement, this ensures that the light has minimal spread as it propagates. Collimating lenses are for examples attached to spectrometers, colorimeters or light meters to ensure that the light that enters the instrument is parallel and covers the relevant measurement area.

A collimating lens system is typically made up of a tube with one or more lenses. By selecting the right properties of the lens and focal distance, light can be collimated with high accuracy. A collimating lens can either be attached directly to the measurement device or via a fiber connection for remote sensing.

Oleophobic & hydrophobic coating is a type of Broadband Anti Reflective (BBAR) coating that resists water, oil, smudges and fingerprints. It is ideal for windows and lenses which are exposed to high-touch or harsh environments. We can coat glass or plastic substrates up to 36″ diameter or 12″ x 30″ rectangular plates.

Typical applications for Admesy products with collimating lenses are found within display measurement applications. Collimating lenses are for example extremely useful when measuring displays, which includes color analysis, white point adjustment, flicker, response time, gamma, etc. The optics are designed in such a way that alignment of the measurement spot can be optimized with stable measurement data and high repeatability as a result. This all contributes to the development and production of high-quality displays.

An anti-reflective coating (AR coating) enhances transmittance. AR coatings improve the efficiency of optical instruments, enhance contrast in imaging devices, and reduces scattered light that can interfere with the optical performance of telescopes, cameras, and binoculars, and decreases glare on eyeglasses.

Collimating lenses can also be used in lighting measurement applications. In particular when measuring diffuse surfaces of light sources such as OLED panels. Similar parameters including spectral power distribution, color and flicker can be determined depending on the measurement device.

Diamond-like-carbon coatings are used across many industries in magnetic storage disks, car and engine parts, biomedical implants, and cutting and forming tools. They are a preferred choice in defense and security applications where environmental factors necessitate an anti-reflective coating with high durability and ability to withstand harsh conditions.

Metallic mirror coating allows you to choose the optimum spectral range of reflectivity and durability for both large and small components. Metallic mirror coating materials include aluminum, silver, rhodium, and gold. Protected and enhanced mirror coatings are available as well.

Omega has the ability to coat large plates and dice down to sub-millimeter scale, or even coat onto individual ~150 micron optical fibers!

Also, analysis applications where for example (spectral) transmission data of translucent materials is important for managing production processes. The advantage of collimating lenses attached to light sources and/or spectrometers is that light enters the sample under one specific angle only, with almost no variation. Again, this contributes to stable and repeatable measurement results.

Admesy supplies a large range of sampling accessories for measurement devices such as spectrometers, colorimeters, and light meters as well as light sources. Within this range, there are various collimating lenses available depending on your application requirements. Lens systems are either connected directly to the measurement systems, or they can all be connected to Admesy’s robust custom optical fiber. Our lens accessories provide flexibility when using a measurement device for research and development, or when integrating it into production lines with limited space for positioning the equipment.
