Precision Mold Technology

1. Vacuum-molding technique

• Molding under high-vacuum(below 0.1 Pa) condition to use a planar-type preform
• Unique design of mold for vacuum molding

2. Molding technique of Diffractive – Aspheric Surfa

• Mass-production of diffractive-aspheric lens
• Fabrication of high-quality diffractive-aspheric lens
• Improve optical performances of IR lens module using diffractive-aspheric lens
