1. A method for joining a first substrate to a second substrate, said first substrate being transparent to optical radiation and including metallization features thereon, said method comprising the steps of:

  • a) placing a curable sealant between said first substrate a nd said second substrate, portions of said sealant partially blocked from said optical radiation by said metallization features; and

    b) placing an optically transmissive block on a surface of said first substrate, in the path of said optical radiation, to direct said optical radiation towards said sealant at an angle that avoids said metallization features from blocking said optical radiation so that said sealant is exposed to said optical radiation and is thereby aided in curing.
