Monochromators come in several basic optical models. Each one provides the same role—separating polychromatic light to monochromatic in some fashion or another. The spectral range dictates the function that influences the monochromator design. Some cover wider ranges, others narrow.

Applications cover many areas, including research, biomedical, semiconductor, petrochemical and industrial settings. Models likewise range from general applications with limited analysis to industrial monochromators for advanced heavy use environments. When buying a monochromator consider the following:

1. Know the spectral ranges for the monochromator your business requires.

2. Plan on future expansion and buy more advanced, multifunctional monochromators to offset later purchases.

3. Save time by knowing in advance the application and type of monochromator needed, as the websites are detailed.

Action Steps
The best contacts and resources to help you get it done

Get double monochromators offering assorted spectral ranges

These monochromators use two concave diffraction gratings and provide high resolutions. Focal length varies with models.

I recommend: Fill out the form for pricing or other requests at McPherson and see the double monochromators by clicking “All Products,” “Monochromators” then model numbers 275D, 270, 2035 or 2035D for deep UV to infrared monochromators. Go to Ohio Lumex and request information or click “Products”; then scroll to “Monochromators” and click to view specs with ultraviolet and visible spectral ranges.

Buy a grating monochromator for your specific application

Each monochromator design provides various functions, slit widths, detections, spectral range and monochromator resolution.

I recommend: For kinematic, holographic, Echelle and ruled grating monochromators contact HORIBA Jobin Yvon; click “Products,” then “Spectrometers & Monochromators” and place your mouse over another “Spectrometer & Monochromators” for current models. Get a monochromator price by contacting On-Line Instrument Systems for double, prism plus double and subtractive double grating monochromators located under “Products—Olis Instruments—DSM CD (Circular Dichroism).” Order a 77250 or 77200 series convex monochromator with interchangeable gratings at Newport.

Find a double crystal monochromator suitable for your business

These devices offer high results data by using crystals.

I recommend: Contact SPECS Technologies for double crystal monochromators; click “Products” then scroll and click “Beamlines, Monochromators, Synchrotron Equipment” for photos and info. Get an industrial grade system that’s cryogenic or water-cooled built to your specification by contacting Advanced Design Consulting USA; place your mouse over “Synchrotron Products” and click “Double Crystal Monochromator System (DCM)” or “Monochromator for Advance Photon Source (APS)” for specs.

Locate a silicon monochromator company for custom or in-stock inventory

Silicon detectors produce wide spectral responses with applications in analytical, biomedical and research settings.

I recommend: Get a visible spectrophotometer using a Jobin Yvon Monochromator with a silicon diode detector from Topac; follow contact info at the bottom of the page. Click “Online store” and select “Spectrophotometers” for UV VIS model. Phone or fill in the form for further information from Optometrics and place your mouse over “Products”; then click “Monochromators & Modules” and choose “Monochromators” for Mini-Chrom models with silicon diode detector modules.

Tips & Tactics

Helpful advice for making the most of this Guide

• •  When requesting a monochromator price or information, consider asking if the company carries in-stock discontinued monochromators. As you know, technology dates most devices sooner than later, which enables discount pricing for legacy products.
