Effect of nuclear radiation on Selfoc microlenses

Abstract :
Exposure of quarter pitch SLS and SLW Selfoc microlenses to moderate radiation doses ~50 Gy has been found to induce optical attenuations of as much as 1 dB at 0.85 ¿m. Although significant recovery is noted in the SLW lens over 24 h following the irradiation, little decrease has been measured in the SLS lens. Spectral measurements of the induced absorption have revealed a monotonic decrease with increasing wavelength (0.6¿1.6 ¿m).
