英文摘要	Opposed surfaces of two optical components are joined by providing at least one of the surfaces with a thin layer (preferably no more than 100 microns thick) of bonding glass having a glass transition temperature Tg substantially lower than the glass devitrification temperature Tcl, placing the surfaces together with only the coating or coatings therebetween, and heating the assembled components under pressure to a temperature Tb which lies between Tg and Tcl and is sufficiently high to soften the glass and bond the components together. Preferably the bonding glass consists essentially of Ge, As, Se and a relatively high proportion of Te. This is particularly useful for components which are thermally sensitive and/or useful in the infra-red, or where there is difficulty in obtaining a component with an acceptable optical surface.
