IDAS UV/IR blocking filters are designed for use with lens optical systems, which are typically not corrected for the UV and IR bands. These filters feature sharp cut-offs, minimized in-band reflections, and incorporate IDAS Multi-Bandpass, Ultra-Fine Polish, and Ion-Gun Assist Deposition technologies to insure un-degraded and extremely durable optical performance.
UV/IR blocking filters are available as camera-body-mounted filters for Canon digital cameras or as screw-in filters in the following sizes:
- 28.6 mm
- 48 mm
- 52 mm
