Description

Spectrophotometer

The present invention relates to a spectrophotometer.

A spectrophotometer is a device for measuring an absorption spectrum. The spectrophotometer includes a visible ultraviolet spectrophotometer for measuring spectra from the near infrared part to the visible part and the ultraviolet part, and an infrared spectrophotometer for measuring the spectrum of the infrared part.

Spectrophotometers generally include a light source, a monochromator (monochromator), a sample chamber, a light detection device, and an electric signal amplification device in a housing. Also, many have a recording device that automatically records the measurement results. Furthermore, in recent years, data files such as measurement data and parameter data are taken in by a personal computer (PC) and processed. Incorporation of the data file to the PC is performed by connecting directly via a cable or the like or by connecting to a network via a local area network (LAN) or the like. However, if direct connection using a cable or the like or network connection using a LAN or the like is performed, there is a problem that labor and cost for installing the apparatus are required.

Under such circumstances, in recent years, an invention has been made that allows data files to be taken into a PC more easily and at low cost, and is disclosed in Patent Document 1.
