Optical instrument and parts thereof for optimally defining light pathways
First Claim
1. An optical assembly for use with an optical instrument, the optical assembly comprising:
- an illumination source for illuminating a sample;
a detection sensor for receiving and detecting light reflected by or transmitted through the sample;
a monitor sensor for receiving and monitoring light from the illumination source; and
an optical piece having a first side adapted to face the sample, the optical piece defining;
an illumination channel extending from the illumination source toward the first side;
a detection channel extending from the first side toward the detection sensor; and
a monitor channel extending from the illumination channel toward the monitor sensor;
wherein the monitor channel extends from the illumination channel so as to not define a direct optical path between the illumination source and the monitor sensor.

Abstract
An optical assembly is disclosed that includes an illumination source, a detection sensor, a monitor sensor, and an optical piece having a first side adapted to face a sample. The optical piece defines an illumination channel extending from the illumination source toward the first side, a detection channel extending from the first side toward the detection sensor, and a monitor channel extending from the illumination channel toward the monitor sensor. A spectrophotometer is also disclosed that includes a circuit board, illumination source and one or more sensors. The circuit board includes an optically transparent region, wherein the illumination source is mounted and situated relative to a first surface of the circuit board, so as to direct light through the optically transparent region. Each sensor is mounted and situated relative to a second surface of the circuit board opposite the first surface.
