The invention relates to a method and a spectrometer for wavelength-dependent measurement of radiation in the range of UV light and visible light, with an entry gap, a dispersive element and a number of sensors comprising pixels, wherein a light path runs inside the spectrometer from the entry slot to the sensors and an imaging element is provided, which focusses the radiation on the sensors, in the case of which a means for defocussing the radiation is provided, which is activatable for the purpose of calibration.

Method and apparatus for calibrating spectrometers

A spectrometer may include a radiation source having a spark generator, an entrance slit, a dispersive element and a plurality of detectors, and a rotatable sector shutter having an axis of rotation and a trigger unit optically coupled to the sector diaphragm. The axis of rotation of the sector shutter is non-parallel to a connecting line between the source and the entrance slit.

Spectrometer having a mechanical shutter

The invention relates to a method for the spectral analysis of metal samples with the following steps:

Method for operating an optical emission spectrometer

The invention relates to spectrometer optics with a beam path from a beam source to a number of electro-optical sensors without spatial resolution, the beam path comprising an entry slot, a dispersive element, and a number of exit slots arranged on a focal curve, wherein furthermore:

Spectrometer optics comprising positionable slots and method for the fully automatic transmission of calibrating adjustments between spectrometers equipped with optics of this type

An optical emission spectrometer for analysis, identification or identity testing of metallic materials, and a method for optical emission analysis of metallic materials with a spectrometer, wherein the spectrometer has at least one arc or spark generator for producing a discharge between an electrode and a workpiece in a spark stand chamber of the generator. A cleansing apparatus for air about the discharge includes a pump for feeding air into the spark stand chamber, and a container through which air can flow. The container contains an alkaline metal or alkaline earth metal hydroxide or another substance that binds COpresent in air.
