Optical Lens, Prism, Mirror, Filter, Coating and Design
Optical lens design is the process of designing a lens to meet a set of performance requirements and restrictions, including cost and manufacturing limitations.
Parameters include surface radius, distance to next surface, material type and selective tilt and center removal, as well as surface profile types (spherical, aspherical, hologram, diffraction, etc.). Further it is a computationally intensive process in modeling how a lens affects the light passing through it. Thus, optical design requires technical skills made through professional skills and rich experience.
A lens focuses or scatters light by refraction, and unlike a prism with the principle of refraction without focusing, the lens focuses light to form an image. Generally, lenses are made of glass or plastic, but there are also liquid lenses using the principle of human eye focusing mechanism. Glass lenses are manufactured to the desired shape through grounding and polishing, while plastic lenses are made by molding.
Prisms refract light to reflect (reflective prism), disperse (dispersive prism), or split (beam splitter) light.Prisms are usually made of glass, but any material can be used as long as the material is transparent and suitable to the designed wavelength. Common materials include glass, plastic and fluorite.
Prisms are designed with different surface angles depending on the application field. ILLUCO produces prisms with excellent surface precision and appearance quality based on 20 years' accumulated know-how and technology.
Mirrors are optical components that reflect light for incident light in certain wavelength range and are used in a wide range of industries such as telescopes, lasers, cameras, and life sciences, astronomy, instrumentation, semiconductors, and solar light.
ILLUCO's optical mirrors are designed and manufactured with a variety of coating techniques to reflect the full range of wavelength or only selective ranges, depending on the application.
An optical filter is an optical component that selectively transmits light in a specific range of wavelengths, namely colors, and absorbs the rest. Generally, an optical filter selectively transmits only long (longpass filter) or short wavelengths (shortpass filter), or blocks both long and short wavelengths through a wavelength band (bandpass filter).
ILUCO produces a wide range of filters ranging from simple color glass filters to narrow bandpass filters with high strength coatings.
ILLUCO produces from the simple anti-reflection coating that reduces unwanted reflections from surfaces commonly used in glasses and photographic lenses, and the high reflector coatings commonly used to make mirrors that reflect more than 99% of the reflected light to more complex optical coatings, for example, a dichroic thin film which produces high reflectivity at a certain range of wavelengths and antireflectivity at other ranges.
