    Abstract: A spectrophotometer 1 comprises a control unit 45 with a warming-up determination unit 452 that determines the completion of a warming-up based on a variation amount of a detection signal in a predetermined duration when a light detector 7 detects a light from a sample chamber without loading the sample. Specifically, the warming-up determination unit 452 calculates a difference between a signal intensity of the detection signal detected by the light detector 7 at the time when the predetermined time passes and a signal intensity of the detection signal detected by the light detector 7 at a previous time and determines that a warming-up is complete when a value of the difference is less than a first threshold value. The warming-up determination unit 452 automatically determines the completion of warming-up independently from the determination by the user.

    Abstract: A system for spectral reading includes a plurality of LEDs, an interface, and a processor. The plurality of LEDs are disposed in a physical array. Light from the plurality of LEDs is enabled to be collimated at a Fabry-Perot etalon. The interface is configured to receive a gap calibration table and power characteristics of a plurality of LEDs. The processor is configured to determine an LED switch table. The LED switch table indicates a set of the plurality of LEDs with power above a threshold at a plurality of wavelengths. The processor is further configured to cause measurement of a sample using the gap calibration table and the LED switch table for a set of gap values and determine measurement results.

    Abstract: In a double-beam photometer comprising a light source providing a light beam, detector means, a sample area, optical means for guiding the light beam as a measuring light beam through the sample area onto the detector means, means for guiding the same light beam as a reference light beam onto the detector means while avoiding the sample area, and chopper means disposed in a splitting location for splitting the light beam into the measuring light beam, which are combined into one path of rays in a recombination location, after the measuring light beam has passed through the sample area, with the splitting location and the recombination location being spatially close to each other. The chopper means has a single chopper which simultaneously effects the splitting and the combination of the measuring and reference light beams.

    Abstract: The apparatus is for use with a surface and includes a light source, a body and a light production apparatus. The light source includes a plurality of elements for generating light. The body: has a planar base for placement in use on the surface, the base being orientated perpendicular to the receiving axis; defines a sampling aperture communicating with the base and through which the receiving axis passes; encompasses the elements; and is adapted, in combination with the light source and when the sampling aperture is blocked to ambient light, to shield the sensor from ambient light. The light production apparatus is for converting the light of the elements through internal reflection, absorption and filtration into light collimated to impinge upon the base, at the intersection of the base and the receiving axis, at a predetermined angle to the receiving axis.
