specbos 1211(UV+VIS+IR)

specbos 1211 is a miniaturized and fast broadband spectroradiometer covering the wavelength range from VIS(UV) to NIR. It can be used for various applications both in lab as well as in production. The instrument is available in a standard version for the wavelength range of 350 ... 1000 nm and in an extended UV version (specbos 1211UV) with 230 ... 1000 nm.

Each front end accessory changes the sensitivity of the instrument, therefore an individual calibration file is necessary for each accessory. Both specbos 1201 and 1211 can store up to 8 calibration sets. The front ends can be coded that up to three calibration files will be selected automatically if the related accessory is attached (the fourth is the calibration of the instrument without accessory).
