1. Apparatus comprising:
- a housing having a cover of transparent material with a predetermined index of refraction;
an array of photosensors deposited in a space within said housing beneath said cover; and
index matching means having an index of refraction substantially the same as that of said index of refraction of said cover,said index matching means being deposited in said space between said cover and said array of photosensors for reducing internal reflections in said housing.
