Frequently Asked Questions

Spectrograph is an optical device which allows breaking, or dispersing, the light into its spectral, or color, components. These components comprising the spectrum of the incident light can then be measured for various purposes. Spectrographs are also referred to as spectrometers.

Monochromator is an optical device used with a spectrograph. It allows selecting a specific portion, or narrow wavelength range, of the light dispersed by the spectrograph for measurements. Wavelength selection may happen mechanically or in an automated fashion depending on the design of the monochromator.

Many factors go into the selection of the spectrograph, or spectrometer, for a specific application. There is a wide range of spectrometers on the market, from compact and user-friendly plug-and-play type devices to high-resolution, large, scientific-grade instruments. Some of the ley parameters when choosing a spectrograph are the optical resolution, operational wavelength range, instrument size, noise specification, camera, software.

A spectrograph can cost under a $1000 dollars and can be more than $30,000, depending on the resolution, spectral range covered, signal to noise specification, etc.,

The main features of Zolix's spectrographs and monochromators include different focal lengths, a rugged Czerny-Turner configuration, interchangeable triple grating turret, and compatibility with various detectors and accessories.

Zolix's spectrographs can be used for Raman spectroscopy, emission and fluorescent spectroscopy, absorbance/transmittance/reflectance measurements, tunable light source measurement and calibration, and detector spectral responsivity measurement.

The double monochromator/spectrograph offers higher spectral resolution when using the dispersion summation mode, making it suitable for high resolution measurements. It also effectively reduces stray light when using the dispersion subtraction mode, making it suitable for weaker signal detection.

Yes, Zolix's spectrographs can be integrated with single point detectors, InGaAs cameras, and CCDs to provide a versatile and sensitive modular solution for different applications.

Zolix provides software that can complete data acquisition for detectors, including single point detectors and CCDs. They also offer LabVIEW drivers for programming to operate the Omni-λ Series spectrographs and monochromators.
