Abstract: A sample clamp as well as systems incorporating the sample clamp with a spectrometer and methods of using these systems are described. The sample clamp includes a first jaw connected to a second jaw by a hinge oriented in the direction of a first axis. The sample claim also includes a substantially cylindrical space oriented longitudinally in the direction of the first axis, defined by a first inner surface of the first jaw and a second inner surface of the second jaw, and configured for clamping a cylindrical object therein. Additionally, the sample clamp includes a conduit oriented in the direction of a second axis and optically connecting the cylindrical space to a first outer surface of the first jaw.

Abstract: A modular accessory for orienting a light path at different angles to an optical axis of a spectrometer is described. The modular accessory includes an attachment module configured to couple to a Raman spectrometer. The attachment module attaches to a base module which includes a visible light imager. An objective module couples to the base module and includes an objective configured to provide an optical path for the sample light beam travelling from a sample along a light path to an objective lens of the objective, through the objective, and to the input for the sample light beam of the base module. The modules can provide tilt and swivel angles to orient the light path at different angles. Portable Raman systems including the modular accessory and a Raman spectrometer are also described as well as methods for using the systems.
