MV-3000 series

Portable spectrophotometer

The portable spectrophotometer MV - 3000 series can measure the spectrum every 5 msec at the shortest. By measuring the spectrum at high speed, it is possible to shorten the time required for product inspection by monitoring production line etc. and mapping measurement. It uses a structure that does not have a diffraction grating driving function and an optical fiber, so it is compact, has good handling, and can be widely used for on-site measurement and other applications.

Features of Portable Spectrophotometer MV-3000 Series

Up to 1000 spectra can be measured continuously

It is possible to measure the spectrum continuously, and you can capture substance changes in a small amount of time with spectral change.

Synchronize with external trigger

By synchronizing with the external signal, you can measure the spectrum at the intended timing.

Start Button

In addition to starting measurement from software, measurement can also be started by the start button mounted on the main unit. It is convenient for routine measurement.

Small size and portability

If it is difficult to bring the sample into the laboratory, you can take the MV - 3000 to the site and measure it.

High durability

Since there is no complicated mechanism such as drive mechanism of the diffraction grating and filter driving, the risk of failure is low.

Spectrum can be measured with a minimum of 5 msec

You can shorten the time to wait for wavelength scanning. In addition, the mapping spectrum measurement time can be greatly shortened.

Hardware features

Small size and portability

Because it is compact and excellent in portability, it is difficult to bring the sample into the laboratory, so you can take the MV - 3000 series to the site and measure it.

Optionally it can be carried by docking the MV - 3000 main body and light source unit, which is convenient for on - site measurement.

High durability

The MV - 3000 series uses a multi - channel spectrophotometer. Since it does not require complicated drive such as mirror switching of the light source and rotation mechanism of the diffraction grating, the risk of failure is low and the number of maintenance is reduced.

Also, if a problem occurs, an error is displayed on the PC, and the error lamp attached to the main unit lights up. Even if you are using it as a monitor of the production line, you can immediately grasp the problem at the work site.

Spectrum measurement at high speed

Up to 1,000 spectra can be continuously measured with a measurement interval of 5 msec. Since high-speed change of sample can be monitored, it can be used for measurement of reaction rate and measurement of moving samples.

In addition, since it can be measured at high speed, measurement time for measurement that is generally time consuming such as mapping spectrum measurement can be drastically shortened.


Pseudo double beam mechanism

When monitoring a long line, you can increase the stability by incorporating a pseudo double beam mechanism into the accessory.

Reference correction is performed between measurement and measurement using the optical path switching mirror (included in the accessory). Since the stability of the spectrophotometer is influenced by the ambient temperature, this mechanism is indispensable for a long time measurement such as crossing the date.

Fulfilling measurement and analysis program

Standard program

In addition to the usual spectrum measurement program, there are an interval measurement program that measures the spectrum at regular time intervals, and a high-speed measurement program that performs measurement at high speed. The analysis program is also substantial.


Option program

Various option programs are available in lineup.

Color evaluation

An emission color measurement program for finding the color of the light source and the issuing body such as a display emitting spontaneous emission, a color diagnostic program for calculating color of various color specification systems as defined by the CIE (International Commission on Illumination), and the like.

Multivariate analysis

CLS (Classical Least Squares) quantification program, PCR (Principal Components Regression) quantification program which can perform quantitative analysis of unknown sample and simultaneous quantification using a calibration curve model, using statistical method multivariate analysis, PLS (Partial Least Squares) quantification program and so on.

Material · Property evaluation

Multilayer film measurement program suitable for multilayer film measurement, film thickness measurement program which can obtain film thickness, etc. are available.

Quantitative measurement

There is a spectrum quantification program which can quantify using the spectral data of the sample.

Measurement example
