The Flat Reference Mirror - Square, 30 mm is an uncalibrated aluminum mirror coated with a protective layer of Magnesium Fluoride (MgF2). Its calibration range is 250-2500 nm, and it comes spectral data for %RC Reflection corrections.
PerkinElmer offers a variety of reference standard mirrors for the purpose of calibrating relative specular reflectance measurements in LAMBDA 650/750/850/950/1050 spectrometers.
