Monochromators act as tunable bandpass filters for light. They are the critical component for many spectral applications since they can be used to create tunable light sources and also to take high precision spectral measurements. The Digikröm line of monochromators, available in 1/8, 1/4 and 1/2 meter focal lengths, use electronics that are “designed-in”, rather than appended via accessories or other add-ons after the instrument has been manufactured. The direct digital drive is simple and reliable; a microprocessor-controlled stepper motor, moving in wavelength increments as small as 0.01nm per step, is linked directly to the grating mount by a worm and worm wheel arrangement. This results in improved accuracy, automatic grating changes and exceptional ruggedness. Because each Digikröm contains its own microprocessor, it is controlled via a standard serial port (RS232), IEEE-488 port (GPIB) option, USB2.0, or with SP’s hand-held controller option. This compatibility allows your computer, for example, to make automatic adjustments of bandwidth through motorized slits, to select gratings, choose scan speeds and to store your changes in memory. This versatility is intrinsic to the instrument.
Spectral Products’ SM line of computer-based miniature array spectrometers offer state-of-the-art performance yet have compact form factors. Their versatile design and ease of use make them a first choice for scientific and industrial applications. SM series optical benches are designed to provide stable operation over a wide range of ambient temperatures. All of Spectral Products’ instruments take advantage of Spectral Products pioneering research in high quality laser optic manufacturing process control.
The Digikröm and SM products lines together with their accessories (light sources , detectors, filters and fiber optic adaptors) are now used throughout the world in such systems as Raman spectroscopy, emission and excitation fluorescence/luminescence spectroscopy, arc, spark or plasma spectroscopy, spectrophotometry, spectroradiometry, laser breakdown spectroscopy, picosecond laser analysis, ratiometry, infrared measurements, process control and calibration. Wide applications of our instruments include semiconductor, biomedical, manufacturing, petrochemicals, pulp/paper, clinical labs, QC labs, research development, pharmaceutical, environmental control, polymers, mining/metals. Whether your need is for high resolution, low stray light, high throughput, or compactness, there is a lowcost Spectral Products system to meet your technical requirements and budget.
