Abstract
Self-aligning light source and detector assembly having a sensor support mounted in a predetermined, fixed position, a light source holder mounted in a predetermined, fixed position relative to the sensor support, a sensor mounted in a fixed position on the sensor support, and a lamp assembly removably mounted to the light source holder in a predetermined position defined by mating surfaces which engage each other and seat the lamp assembly in the predetermined position whenever the lamp assembly is installed in the holder.
Claims10
A self-aligning light source and detector assembly, comprising:
- a mounting block, a sensor support mounted to the block in a first predetermined, fixed position, a light source holder mounted to the block in a second predetermined, fixed position, a sensor mounted on the sensor support in a fixed position, a lamp assembly removably mounted to the light source holder in a predetermined position defined by mating surfaces which engage each other and seat the lamp assembly in the predetermined position whenever the lamp assembly is installed in the holder, and a mirror for directing light from the lamp assembly toward the sensor when the lamp assembly is seated in the predetermined position.
A self-aligning light source and detector assembly, comprising:
- a sensor support mounted in a predetermined, fixed position, a light source holder mounted in a predetermined, fixed position relative to the sensor support, a sensor mounted in a fixed position on the sensor support, and a lamp assembly removably mounted to the light source holder in a predetermined position defined by mating surfaces which engage each other and seat the lamp assembly in the predetermined position whenever the lamp assembly is installed in the holder.
A self-aligning light source and detector assembly, comprising:
- a mounting block having first and second generally parallel bores with axially facing internal shoulders, a first support tube having a first portion in abutting engagement with the annular shoulder in the first bore and a distal end portion extending from the mounting block, a second support tube having one portion in abutting engagement with the annular shoulder in the second bore and a distal end portion extending from the mounting block in a direction generally parallel to the distal end portion of the first support tube, a sensor mounted in a fixed position on the first support tube facing the second support tube, a lamp assembly removably installed in a predetermined position in the second support tube with a portion of the lamp assembly in abutting engagement with an axially facing annular shoulder in the second support tube, an aperture for light in a side wall of the second support tube, and a mirror for directing light from the lamp assembly through the aperture to the sensor.
