AngstromLink OKP Optical Plastic Series

The OKP Optical Plastic Series products are high-purity, optically clear thermoplastics designed especially for the injection molding of high-performance optical components, such as phone and camera lenses, LEDs, and display backlights.

The OKP products feature a high refractive index (1.61, 1.63, 1.64, respectively) and light transmittance comparable to optical-grade polycarbonate. They have high heat resistance to withstand lead-free soldering processes and excellent optical and thermal stability. These products are supplied in pellet form, consistent with normal injection molding processes.

• OKP4 Optical Plastics: Digital and video camera lenses
• OKP4HT Optical Plastics: Mobile phone lenses
• OKP-1 Optical Plastics: Where low birefringence is advantageous
• Optical films to assist light extraction, light redirection
• Secondary optics that modify the light radiation pattern and/or provide protection from the environment
• Color Aberration Correction

• High Refractive Index ( >1.60 ) - Increased numerical aperture for the system
• Injection moldable - High fluidity for injection molded parts undistorted by stress
• Optical transmission comparable to polycarbonate - Higher refractive index and lower birefringence than polycarbonate
• High environmental resistance - Rugged material that can provide long-term service
• Low Abbe number - Higher levels of correction of chromatic aberration can be achieved
• Wide temperature service - Ensures stability of performance
