Home / Custom / Optical Components / Aspherical Lens / Molded Glass Aspherical Lens 
By using precision molding technology to form optical glass materials in a high-precision mold in one step, high-performance aspherical lenses can be mass-produced at a lower cost, effectively correcting aberrations and significantly reducing the size and weight of optical systems.
Corrects spherical aberration, improving spot quality and image sharpness.
RMS 20nm
High thermal stability, resistant to chemical corrosion, UV resistant, and long lifespan.
High initial mold investment and high sample price; low unit cost and high production efficiency in later mass production.
