An optical measurement system measurement system for examining a sample. The measurement system comprises an internally reflective element, a stage, an optical assembly, a chassis, and a sensor. The internally reflective element has a contact surface. The stage is positioned below the internally reflective element. The stage and the internally reflective element are configured to apply a force to the sample. The optical assembly comprises a light source and a light detector. The optical assembly is configured to scan the sample by directing source light from the light source towards the contact surface and detecting source light optically interacting with the contact surface by the light detector. The chassis is configured to support the optical assembly and the internally reflective element. The sensor is mounted to the chassis and configured to detect the force applied to the sample by the internally reflective element and the stage.

Method and apparatus for determining a force applied to a sample during an optical interrogation technique

A laser mount assembly includes a lens holder including a collimating lens. A laser subassembly is positioned adjacent the lens holder and includes a vertical-cavity surface-emitting laser, a thermal electric cooler, and a thermistor. A printed circuit board is positioned adjacent the laser subassembly and includes a plurality of heating components. The heating components heat the area between the lens holder and the laser subassembly.

Vertical-cavity surface emitting laser support assembly

The present invention is directed to a spectrophotometer instrument that includes an arm that can swing between a closed position and an open position which is upward and backward of the lower position and wherein the display is moveable between a position behind the arm to a position to a side of the arm. Thus, the features herein provides the instrument user with positioning features to allow for a superior human factors user experience.
