Topcon SR-2 Visible-Range SpectroradiometerFully operational, calibrated, and function-tested. The instrument powers on normally, completes measurements, and has produced stable, repeatable results during testing.The SR-2 covers the visible wavelength range from 380 to 780 nm and is designed for precision spectral radiance, luminance, and chromaticity measurements. It is suitable for LED and display characterization, lighting analysis, optical research, color measurement, and laboratory source evaluation. Included:* Topcon SR-2 spectroradiometer
* AC power cable
* Serial communications adapter
* Front lens capNot included:* Carrying case
* Computer or additional software
* Other accessories not shownThe unit has normal cosmetic wear consistent with laboratory use. Please review the photographs for exact physical condition. The optics have been protected with the included lens cap.Comes from my working lab. I am selling it because I have consolidated my optical measurement work around other spectrometers, so this instrument is now surplus to my needs.Calibration note: Last calibrated fully by Japanese University. Unless specifically stated otherwise, no current third-party or NIST-traceable calibration certificate is included. I have calibrated against known sources and it is accurate.I can provide additional photographs or a short video showing startup and a live measurement before purchase.Due to the sensitivity and value of the instrument, it will be carefully foam-packed, double-boxed.
