| 英文摘要 | PURPOSE:To improve the directivity with relatively high intensity thereby to provide high sensitivity with high condensing efficiency by providing a first micro Fresnel lens for collimating an irradiated light from a light emitting element in a window and a second micro Fresnel lens for condensing an incident light to the light emitting element on its photodetecting surface. CONSTITUTION:A light emitting element chip 4 is mounted on a heat sink 3, and a photodetector chip 5 is mounted on the other part on a mount The chips 4, 5 are covered with caps 6, and a cap 6 is secured to the mount 1 by normal method, such as can sealing, bonding, fusion-bonding. windows 6a, 6b are respectively opened at places corresponding to the chips 4, 5 of the top of the cap 6, i.e., at emitting light passing position of the chip 4 and at incident light passing position to the chip 5, and micro Fresnel lenses 7, 8 made of transparent resin are mounted therein. The lenses 7, 8 are secured by bonding to the inner peripheries of the windows 6a, 6b at the peripheral edges. |
