The MFR, UVMFR, and SPUV all use new technology “Ion Assisted Deposition” interference filters. The slit width and effective center wavelength are exceptional and stable. However, while the throughput/transmission of IAD filters is far superiror compared with previous generations of optical filter technologies, we still recommend that yearly factory calibrations.
