Abstract:
1. A spectrometer comprising: a base plate; a light source mounted to the base plate and configured to transmit light; an interferometer mounted to the base plate, the interferometer receiving light from the light source and outputting modulated light; an accessory compartment configured to accept a sample analysis accessory device, the accessory compartment comprising a sample analysis device mounted to the base plate and separated from the accessory compartment by the first wall, the sample analysis device configured to perform attenuated total reflectance analysis of a sample and comprising a first optical element mounted to the base plate and configured to receive and to reflect the modulated light toward the first light port to form the first light; a second optical element mounted to the base plate; and an actuator mounted to the second optical element and configured to move the second optical element between a first position and a second position, wherein, in the first position, the second optical element is configured to receive the modulated light and to reflect the modulated light toward the crystal to form the second light such that the first optical element does not receive the modulated light, and further wherein, in the second position, the second optical element does not receive the modulated light.
