ABSTRACT:
A telemicroscope has a light absorbing and blocking annular baffle within the telemicroscope barrel. The baffle is positioned between the front and rear lenses and reduces glare in the telemicroscope by blocking and absorbing light which would ordinarily reflect off the inner surfaces of the telemicroscope barrel. The baffle has a knife-edge inner diameter and its surfaces are given a dull finish to enhance its light absorbing properties.
