Most spectrophotometers are either single-beam or double-beam. Single-beam spectrophotometers are used to examine relative light intensity before and after a test sample is introduced, while double-beam spectrophotometers are used for comparing light reference paths and the substance being measured. Single beams are overall more compact and have a higher dynamic range, yet double beams are preferable in environments that require equipment that is less sensitive to fluctuations.

These collimators can be glued into a 2D array with high precision and all light channels are thus parallel. The type of fiber, the operating wavelength, the working distance and other parameters could be defined by the customer.

Opticalspectrometer

Many spectrometers, especially those found in telescopes, also contain a collimator, a device that aligns different wavelengths into a parallel array. The light then reaches a detector that senses the individual wavelengths.

The lenses can be designed according to the customer requirements. Standardly all of the paramaters are simulated in ZEMAX software.

Spectrecology provides free technical support on all purchases as well as application support and consultation. We even offer our products for rent so you can see how they’d work on your job site without the risk. We offer a rent-to-buy program as well, meaning you can put your rental payments toward the cost of an instrument without losing money from past rental payments.

Spectrophotometers are otherwise known as UV-Vis spectrometers. The output of a spectrophotometer is usually measured in the absorption spectrum of the sample. There are four main performance indicators you need to consider before choosing a spectrometer or spectrophotometer:

At Spectrecology, we create modular spectral measurement solutions built for use in environmental, educational, medical and industrial disciplines. Since our founding as Ocean Optics in 1989, we’ve gone on to develop more than 3,000 miniature fiber optic spectrometers and chemical sensors. We specialize in cost-effective modular equipment that allows you to get faster and more efficient measurements than the competition. We create the following pieces of equipment:

Spectroscopy refers to the study of radiated matter and how it interacts with radiated energy. As matter absorbs energy, the material becomes excited and causes a visual change that we recognize as color on the visible spectrum. While spectroscopy studies how radiated matter interacts, spectrometry is the study of the color spectra produced by that radiated matter.

*) For higher number or density of fibers in 2D fiber arrays we offer the option to use MLA instead of single collimators.

Spectrometers are useful for analyzing light as well as samples of material. Astronomers, for instance, often use spectrometers to analyze light from space and determine the composition of stars or other objects.

What isspectrometerin Chemistry

Scientists rely on spectrophotometers to give them reliable wavelength results with precious samples as small as 1uL. Spectrophotometers are capable of measuring the diffusivity of light ranges anywhere between 200-2500nm within the electromagnetic radiation spectrum. The following scientific disciplines depend on spectrophotometers to make advancements:

A spectrometer is an instrument that detects and analyzes light waves to measure a substance’s physical characteristics over a spectrum.

Spectrophotometry requires special instruments that are capable of both observing the change in radiated matter and the colors it produces. Learn more about whether spectrometers or spectrophotometers are right for your project with Spectrecology.

The ability of spectrometers to measure the emitted electromagnetic radiation that results from spectra is essential in many scientific disciplines. The following disciplines depend on spectroscopy:

Since all spectrophotometers contain a spectrometer, there are many similarities between the devices. Both instruments measure light in nanometers, with the visible range falling between 380-780 nanometers and the ultraviolet range falling from 10-380 nanometers. Like mentioned previously, spectrometers measure the radiated matter of light, while spectrophotometry measures the color it produces.

What isspectrometerused for

Spectrometers and spectrophotometers are used alongside each other in disciplines including chemistry, biology and pharmaceuticals. Since all spectrophotometers contain a spectrometer, you can frequently use a spectrophotometer for all of your sample analysis needs. With a spectrometer and spectrophotometer together, you can study particle interactions, composition and colorimetry.

To use a spectrometer, researchers often start by loading a sample of a particular substance and vaporizing it. As light passes through the vaporized substance, the spectrometer splits the light into its discrete wavelengths. It creates a spectrum of separate colors, similar to the rainbow created with a prism. These different-colored wavelengths are useful for determining the nature of the substance in the spectrometer.

Spectrophotometers quantitatively measure light intensity using wavelengths. They contain a spectrometer inside to quantify the amount of light and the type of waves that pass through the instrument. Light experiences the following process in a spectrometer:

Both spectrometers and spectrophotometers are preferred across scientific disciplines for their non-destructive testing capabilities. Spectrometers and spectrophotometers differ in the following applications:

SQS Vláknová optika has developed highly precise fiber optic collimators with low angular misalignment of the optical beam against the collimator geometrical axis. These collimators are designed to minimize insertion loss for signal passing through the air gap.
