Light attenuator and process for fabrication thereof.

摘要

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 placing the thermoplastic resin on a release film or paper and heating and press-bonding to the end face of a light-transmitting rod or stick so that the light attenuating layer of thermoplastic resin is transferred to the end face of the rod or stick when the release film is removed.
