DTMc300 Triple Grating Monochromator

Product catalog summary

Overview: The DTMc300 is a double monochromator designed for applications requiring superior scattered light performance. It combines two TMc300 monochromators in tandem, offering flexibility and a wide spectral range within a single scan. It is compatible with Bentham's range of sources, detectors, and accessories.

Key Features:

Double monochromator with two 300mm focal length monochromators in Czerny-Turner configuration for additive or subtractive dispersion.
Each monochromator can hold up to three diffraction gratings, allowing single-scan measurements over a spectral range of 200nm-50µm.
Supports up to two entrance ports and one exit port in single mode, and up to two exits in double mode, with automated mirror-based port selection.
Fully automated via USB 2.0 interface.

Optical Layout:

Pair of symmetrical Czerny-Turner monochromators for additive or subtractive dispersion.
Total focal length of 600mm (additive), with individual units at 300mm.
Triple grating turret with 1-3 gratings, grating size of 68 x 84mm, and aperture ratio of f/4.1.

Optical Performance:

Spectral range from 200nm to 50µm.
Linear dispersion of 1.35nm/mm (additive).
Wavelength accuracy of ±0.1nm and reproducibility of ±0.025nm.
Resolution of 0.15/0.05nm (full/reduced slit height).
Stray light rejection at 2.5 FWHM of 10^-8.
Wavelength acquisition speed of 2000nm/s.

Automation and Control:

Controlled via USB with BenWin+/SDK software.

Physical Specifications:

Dimensions: 634W x 360D x 211H mm.
Optical height: 115mm.
Weight: 28 kg.
Power supply: 110/220V 50/60Hz.

Options:

Diffraction gratings and order sorting filters available separately.
Filter wheel options: 252-6 or 252-8 (includes shutter).

Catalog excerpts

For those applications where the scattered light performance of a single monochromator is not sufficient, the excellent optical performance as the TMc300 may still be experienced with two of such used in tandem constituting thereby the DTMc300 double monochromator. The DTMc300 maintains the flexibility of configuration and ability to cover a wide spectral range of the TMc300, within a single scan. Compatible with the full range of sources, detectors and accessories of the Bentham portfolio, in the additive dispersion mode, the DTMc300 monochromator is at the heart of many of our light measurement...
