OKP /AL62

ÅngstromLink AL-6261, 6263, 6264, 6265 (OKP4, OKP4HT, OKP1, OKP850*) are high purity optically clear thermoplastics designed especially for injection molding of high performance optical components such as phone and camera lenses, and display backlights.

 

AL-6261, 6263, 6264 & 6265 feature high refractive index (1.61, 1.63, 1.64 & 1.65 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.

Applications

AL-6261 - Digital and video camera lenses
AL-6263 - Mobile phone lenses
AL-6264 - Where low birefringence is advantageous
AL-6265 - High heat applications / High refractive index
