DK Monochromator and DK Spectrometer

Features

-Triple-grating turret allows high efficiency scanning across a broad spectral range with motorized slits

- May be factory configured as a monochromator or spectrograph.
- Scans in both directions and with Constant Spectral Resolution (CSR)
- Integrates with SP filter wheel for automatic filter switching
- Suitable for fluorescence and absorption studies, detector characterization, thin film measurements, etc

- Connects to any computer via RS 232 or IEEE-488.

 Visit the Specification Sheet Tab for details on performance and resolution.

The Digikrom DK Monochromator and DK Spectrometer Series has two sets of focal length at 240mm & 480mm. The systems is a completely computer integrated solution with user friendly commands to control the triple grating turret, motorized slits, and optional motorized filter wheel for quick and easy sorting. The DK/DKSP system can be set for constant spectral resolution(CSR), where the slit width is automatically modified to compensate in the change in dispersion with wavelength to maintain constant spectral bandpass. 

Rugged cast construction, A-Thermal design, and SP direct grating drive make this unit very reliable in its class. Each instrument is calibrated and certified prior to delivery.

Gratings and Optical Resolutions

Gratings are to be ordered along with DK240 and DK480 allowing users to order their desired grating to meet their needs.

Operations

Each Digikröm contains its own microprocessor, it is controlled via a standard serial port (RS232), IEEE-488 port (GPIB) option, 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.

Terminology Guide

Wavelength Precision

It is the ability of the device to return to the same wavelength. The measured wavelength by the equipment should not drift over the range provided.

Wavelength Accuracy

It is a measure of the deviation of the wavelength when the standard wavelength is measured. You would expect the vaue of the wavelength to be the standard value with the deviation everytime you take a measurement.

Wavelength Resolution

It is the the ability of the instrument to differentiate between different wavelength of light.

Slewing speed

It is the rate which the wavelength is being read. 

Bandpass

The range of frequencies or wavelengths that can pass through the slits

DK240/480 Demonstration Software-Windows™ 

DK series monochromator demonstration software is written in Microsoft® Visual Basic™ 16 bit, Ver. 4.0 for Windows™ and will run on Windows™ 3.11, 95, 98, 2000, and NT 4.0. The demonstration software, along with instructions for operation, is found on the CD software disk. If you are interested in writing custom software that supports the DK240/480, we will be pleased to send this source code upon request. If you have any questions about the operation of your monochromator or if you have suggestions, please contact us. We appreciate your comments and suggestions.
