Abstract: To provide sufficient sensitivity, spectral resolution and speed of measurement for field environmental measurements in a portable spectroradiometer, a silicon photodiode receives light: (1) having a bandwidth in the range of between 2 and 15 nm (nanometers) from a pivotable concave holographic diffraction grating within the wavelength range of between 250 and 1150 nm at a scanning rate in the range of 20 to 100 nm per second; (2) having stray light of high intensity and undesired frequencies and the shorter wavelength harmonics of the selected frequency range blocked by filters; and (3) having flux of at least 10 microwatts per square meter of diffuser plate for each nanometer of bandwidth. Automatic electrical zeroing is obtained by blocking all light once at the beginning of each scan, obtaining an electrical drift-related signal and using the drift signal to adjust the measured signal during the scan. Several different sensing interfaces can be used, including a quartz, light fiber probe having at least a 50% packing density and a cone angle of at least 24 degrees. The data and the programming storage is at least 30K bytes but the instrument uses no more than watts of power when the instrument is not scanning.

Abstract: A tiny and portable micro-spectrometer deployable in a bullet-like form that is inexpensive to the point that it can even be disposable is described. The device is based on the micro-spectrometer that uses the Fresnel diffraction principle that allows a tiny implementation with a nanometer resolving power of spectral signal. A bullet-like micro-spectrometer has an integration of a super capacitor as a power source, a charging coil for the super capacitor, an LED or laser diode light source and driver, an analog to digital converter (ADC) circuit, and a telemetry system with antenna string. An LED or laser diode runs in a burst mode to generate deep or vacuum UV to excite target material. When the excited state of target material undergoes a singlet or triplet transition, this transition process yields fluorescence or luminescence which is a material-dependent. The micro-spectrometer senses and uses this spectral emission from material to identify the spectral signature of the targeted material. The data is converted by an ADC and transmitted to a receiving station.

Abstract: A protective sheath having a closed end and an open end is sized to receive a hand held spectrometer. The spectrometer can be placed in the sheath to calibrate the spectrometer and to measure samples. In a calibration orientation, an optical head of the spectrometer can be oriented toward the closed end of the sheath where a calibration material is located. In a measurement orientation, the optical head of the spectrometer can be oriented toward the open end of the sheath in order to measure a sample. To change the orientation, the spectrometer can be removed from the sheath container and placed in the sheath container with the calibration orientation or the measurement orientation. Accessory container covers can be provided and placed on the open end of the sheath with samples placed therein in order to provide improved measurements.
