ABSTRACT:
Disclosed is a light attenuator comprising a stick or rod composed of a light-transmitting material, and a light-attenuating layer composed of a thermoplastic resin and formed on at least one end face of the stick or rod, wherein finely divided particles having a light-absorbing or light-scattering property are uniformly incorporated in the thermoplastic resin. This light attenuator is made by forming a light-attenuating thermoplastic resin layer having incorporated therein the light-absorbing or light scattering finely divided particles on a release film or paper; placing the light-attenuating layer formed on the release film or paper on a heating plate; press-bonding the end face of a rod or stick composed of a light-transmitting material inserted and set in a ferrule to the surface of the release film or paper; cooling the bonded assembly; and then peeling the release film or paper to transfer the light-attenuating layer to the end face of the light-transmitting rod or stick.
