UV Spectrophotometer Introduction

UV Spectrophotometer

A UV Spectrophotometer is a piece of equipment which is used to determine the radiation intensity of light so that concentration, color and other significant information of a product or object can be evaluated. It is basically an electronic device which working function is based on the principle of photo spectrometry by relating the photon characteristic with the wavelength of light. It can measure the intensity of normal light as well as the intensity of infrared radiation. Different electromagnetic spectrum and electric transitions can also be identified by a UV Spectrophotometer.

Reflectance measurement, linear energy absorption range and spectral bandwidth are the key features of a Spectrophotometer. In order to determine the radiation intensity, UV Spectrophotometer sends a beam of light through a test piece and measure the absorption energy of the test piece. From the sum of the absorption energy, intensity of radiation is calculated. Ultimately concentration, color and other significant criteria of the test piece is computed. That’s why UV Spectrophotometer is not only used in the laboratory or scientific research but also widely used in different industry to estimate the characteristics of their manufactured products.

Different Types of UV Spectrophotometer

Though there are a variety of UV Spectrophotometer are present in the market, but most of the people appreciate three different types of UV Spectrophotometer which are UV single beamed, UV double beamed and UV split beamed Spectrophotometer. These UV Spectrophotometer can identify the color properties of an object which radiation intensity range is almost 400 to 700 nm.  At high radiation these can also measure fluorescence radiation spectrum.  This spectrum is very important for the accurate measuring of color properties of many objects.

By estimating the relative radiation intensity of the light beam before and after the test piece is inserted, a UV single beamed Spectrophotometer measure the properties of the object. Whereas a UV double beamed Spectrophotometer measure the properties of the object by comparing the radiation intensity of two light beam paths. One path is for test piece and another for reference sample.  Though UV single beamed Spectrophotometer has a large dynamic range but UV double beamed Spectrophotometer is more preferable due to ease in operation and more stability.

Formats for A UV Spectrophotometer

D/8 and O/45 are the different two formats of UV Spectrophotometer. For the analysis of spherical circumstance D/8 format is used whereas O/45 is used for the analysis of linear circumstance. Both formats are widely used in order to recognize light sources as well as various types of environmental objects. And this is done by analyzing the observed photo effects.

There is no doubt this photometer is really essential in the field of modern industry. The importance of the use of UV Spectrophotometer can be easily highlighted by giving an example of ink industry. Only a UV Spectrophotometer can ensure the correct color composition of ink.  Users must make the correct decision, whether they have needed a UV Spectrophotometer or not. Based on the information above users will have a much easier time selecting a uv spectrophotometer to fit ones needs.
