About This Product

■High-precision glass optical components

Resin lenses and optical components are now used in a variety of fields, taking advantage of their flexibility in shape, lightness, and excellent mass production. However, in areas with extremely high optical power density such as laser processing machines, optical elements for ultraviolet rays that resins are not good at, and optical systems that require severe environmental resistance, glass, which is physically and chemically stable, is used. Optical elements are essential. NALUX also mass-produces glass optical elements using high-precision glass molding for optical fields that cannot be handled with resin optical elements. We will make optimal proposals according to customer requests, such as selecting materials according to the application and combining resin optical elements and glass optical elements.

■Characteristics of glass optical elements

・Low coefficient of thermal expansion and small temperature fluctuations ・High temperature resistance, energy density resistance, weather resistance, and chemical resistance ・Wide variation in refractive index and dispersion ・Small water absorption and photoelastic constant ・Wide transmission wavelength band (near ultraviolet to near infrared) A cylindrical lens is a lens composed of a cylindrical surface that has refractive power in only one direction. It is used in a wide range of fields such as fiber laser processing machines, LiDAR sensors, and optical communications.

■Characteristics of NALUX aspherical cylindrical lenses

・Established NALUX's unique manufacturing method for glass cylindrical lenses, which is highly accurate, has little variation, and has excellent mass production. We also support mass production of over 1 million units per month. Made of glass with excellent heat resistance, environmental resistance, and light resistance, it is ideal for applications that require reliability and applications that are subject to harsh temperature environments. In addition to aspherical glass cylindrical lenses, which are difficult to mass produce using conventional manufacturing methods, we also specialize in meniscus lenses, cross cylindrical lenses, and cylindrical lens arrays. ・One of Narux's characteristics is that we listen to your requests and make design proposals optimized for each project. We provide optimization proposals that take into account not only optical specifications and lens production constraints, but also the customer's manufacturing process. Please feel free to contact us.
