Aspherical Molded Glass Lenses with Metal Holder (Collimator Type) High coupling efficiency and high reliability achieved by a stainless holder integrated lens. Lens integrated holder enables resistance and laser welding to tightly secure the lens. Free from the aberration in spherical lenses with less dispersion. Features A wide variety of lenses available to meet customer needs-high NA products for high coupling efficiency, compound products, convex holder lens. Antireflection coating practically eliminates deterioration under high temperatures and humidity. Custom design of visual ray wavelength, for laser projector, etc. Pb-free glass type equivalent to the conventional shape and specifications are also available in all models.
