Build your own system from a variety of monochromator types, gratings, detectors and input optics. There are numerous possibilities that will meet your test and measurement needs.

Monochromators are offered in these configurations:

Small Series: Compact and affordable, single or double, additive or subtractive

Standard Series: Classic monochromator design (some models), single or double, additive or subtractive, manual or motorized.

An overview of the Standard Series monochromator (click for full size)

High-Resolution: Single, double or triple versions; designed to meet the most demanding measurement task.

There is also the SciVidi, a high-performance spectroradiometric system. The SciVidi System is designed to measure relative and absolute intensities of flash and continuous lamp sources over a wide range of wavelengths. The spectroradiometer is based on an asymmetric Czerney-Turner scanning monochromator design. The system can hold up to 3 gratings for an F/3 aperture. Up to 2 gratings can be selected for a system with an F/2.5 aperture. Applications include: solar radiation measurement, solar simulator testing/classification and light source metrology. Ultimate system resolution can be tailored to meet your requirements.

We also offer complete systems for these specific applications:

• Fluorescence
• Raman
• Far IR
• Spectrophotometry
• Detector Spectral Response Characterization

What is the required resolution?

Resolution gets better (smaller number) when: The focal length of the monochromator is increased The slit size is reduced at the entrance and exit of the monochromator Grating line density is increased.

What is the required spectral range of the system?

Scanning monochromators can provide a wide range of wavelengths, especially with triple grating turrets. All monochromators that Sciencetech builds have mechanical limitations to their spectral range. Just because a grating efficiency curve goes to 100um doesn't mean the monochromator is capable of achieving that wavelength.

Do you need to cover the entire range in a single scan?selectYesNoNot sure

What is the required bandpass?

The bandpass is the spectral range that the system can pass for a given slit width at the input and output of the monochromator, OR for a given input slit width and output detector array size.

Do you require sort order filtering?selectYesNoNot sure

If sort order filter is not included, then orders of wavelengths will overlap.

Do you require a Detector? selectYesNoNot sure

Choosing the right detector depends on sensitivity requirements, spectral requirements, area and bandpass Some detectors require modulated light (we can do this with a chopper) All detectors require a data acquisition system. Detectors require power supplies.

Single channel detector or area detector?selectSingleAreaNo preference

Do you have your own calibrated light source?selectYesNoNot sure

Are you more concerned with resolution or signal?selectResolutionSignalNot sure

The higher (better) the resolution, the less signal will come through the system.

Should the system be capable of having more than one detector at a time?selectYesNoNot sure

Do you require any additional signal control equipment (chopper, lock-in amplifier, order-sorting filters, etc…)?selectYesNoNot sure
