Abstract
Apparatus for clampingly supporting a source lamp in an optical, analytical instrument. The apparatus includes a heat distributing, metal corset encircling the lamp and a clamp member. The clamp is adjustably mounted in the instrument by a mechanism which permits rotational adjustment of the clamp about an axis perpendicular to the optical axis of the instrument and translational adjustment of the clamp along the same axis. The lamp is supported in the clamp in a stable configuration regardless of irregularities in its glass envelope.
Claims14
In an optical apparatus including a base member, a substantially cylindrical radiation source lamp having a sidewardly projecting cylindrical protrusion, and a holder for adjustably positioning said lamp to direct radiation along a preselected optical axis, the improvement which comprises:
- first and second pivot members intermediate said base member and holder on an axis of rotation substantially perpendicular to said optical axis;
- means intermediate said base member and holder defining a linear groove parallel to said axis of rotation and receiving said first and second pivot members therein;
- means for resiliently urging said holder in a first direction of rotation about said axis of rotation;
- means for adjustably restraining said holder from rotation in said first direction of rotation;
- and means for adjustably translating said holder along said axis of rotation by linear relative movement between said groove and said first and second pivot members.
