Abstract: A sine bar mechanism comprises an arm (9) of radius R which is pivoted about an axis (13) which is also the axis of a diffraction grating. An elongate member (6) is pivotally mounted at one end (7) and is pivotally connected to the arm (9) at its other end (8). The co-ordinates (x,y) of the point (7) and the length of the elongate member (6) are chosen to optimise the characteristics of the mechanism. Embodiments in which the elongate member (6) comprises a lead screw and the pivotal connection (8) comprises a nut which is pivotally mounted on the arm (9) and which engages with the lead screw are described and their use in various types of monochromator portrayed.

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 a 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 ad- just 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 two watts of power when the instrument is not scanning.

The moving mechanism expediently comprises means (41,33) for altering the distance between said points (A) of the Rowland-circle (R) lying diametrically opposite to the optical device and said at least one slit. and said member ( 33 ) translating or rotating proportionally to said distance is a part of said means (Figure 3).

Abstract: Disclosed herein is a spectrophotometer which includes a source of radiation (10); an optical system (12, 16) for forming a beam of radiation from the source (10) and directing it along a sample path (22) and along a reference path (24), which paths come together at a location to form a combined path (32) that impinges on a detector (58); a chopper (28) mounted at said location for successively directing one or the other of the beams (22, 24) along the combined path (32) or providing a blank chopper area for blocking radiation from the combined path (32); a monochromator (40) having a grating (44) AND SLITS (38, 46) disposed in the combined path (32), the angular position of the grating (44) being adjustable for passing selected successive wavelengths of radiant energy through the optical system; and controls are provided for controlling the movement of the grating (40) AND/OR SLITS (38, 46) so that movement only occurs when the blank chopper area is blocking the combined path (32).

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.
