Spectrophotometers
A spectrophotometer is a piece of equipment used to measure the absorbance of a sample, as a function of the wavelength of electromagnetic radiation. There are several types of spectrophotometers. These are grouped according to the type of sample analyzed; There are atomic absorption and molecular absorption (commonly known as a UV-VIS spectrophotometer).
Spectrophotometers are used in laboratories to determine what the beam of electromagnetic radiation or light is and thus identify, qualify and quantify what its intensity is like. In the same way, it allows determining its efficiency, sensitivity, resolution and spectral range. Which will depend on the variabilities of the design and the choice of the optical components it contains.
Types of laboratory spectrophotometers a Laboratory may need
Benchtop Spectrophotometer
Benchtop color haze meter is developed by Kalstein independently with proprietary intellectual property. This machine adopts transmittance optical geometry d/0 (diffused illumination, 0-degree viewing angle) which confirms to CIE 15 standard. It can also realized the the optical geometry 0/0 (parallel illumination, 0-degree viewing angle).
Color haze meter uses 360~780nm composite full spectrum LED light source (which is closed to the spectrum of D65), and it can realize intervals 10nm spectrum by precision concave grating and 256 Image Element CMOS Sensor. Accordance with industry-standard, YR053409 will give the accuracy result for the measurement of haze, transmittance, chromaticity, color difference, WI, YI, Pt-Co Index and Gardner index etc. It is wildly used in the field of glass processing, plastic processing, film manufacturing, display screen processing and packaging industry, liquid pharmaceutical analysis, laboratory etc.
