VIS lenses are a gorup of lenses, that are specifically optimized to operte in the visible spectrum of light, so typically within 400-700 nm.
Solaris Optics manufactures custom visible light lenses in its facilities in Poland.
Visible spectrum lenses are used for various imaging purposes, so good imaging properties are of design focus. Therefore typical materials selected for VIS lenses include fused silica, N-BK7 or other Schott standard optical glasses.
Typically performance and mechanical properties of such lenses are further improved by depositing thin film coatings, to e.g. reduce reflections (AR coatings) or reduce transmission of undesirable infrared and/or ultraviolet wavelengths.
Applications of visible lenses
Applications for visible lenses include imaging optics, so any optical devices that rely on human vision and that do not introduce any intermediate digital modifications to light. Example products include e.g. microscopes, spectacles or telescopes.
