Monochromator by Edmund Optics

Note: Your Quotation Request will be directed to Edmund Optics.

The 56-253 from Edmund Optics is a manual mini-chrom Monochromator that has a wavelength resolution of 750 nm - 1700 nm. It has a linear dispersion of 15.42 nm/mm, and a focal length of 74 mm. This monochromator has an aperture size of F/3.9 and a blazing wavelength of 1200 nm. It has a 2 cm2 square gold-coated ruled grating with a slit width of 300 µm. This monochromator has a slit resolution of 1.54 - 9.24 nm and a groove density of 830 grooves/mm. It has a wavelength accuracy of ±0.2% and wavelength reproducibility of ±0.15%. This monochromator has a damage threshold of 350 mJ/cm2 in pulsed mode, and 40 Watt/cm2 in the CW mode.

The 56-253 utilizes a knob dial for wavelength selection whose rotation causes the rotation of the diffraction grating which selects the required wavelength at the exit slit. It has gold-coated optics for maximum grating efficiency and superior reflectance in the near-infrared. This monochromator is available in a compact, in-line Fastie-Ebert design that measures 139 x 59 x 49 mm and is ideal for system integration, clinical chemistry analyzers, HPLC detectors, UV-VIS-NIR spectrophotometers, research, quality control, and teaching applications.
