Irix Edge MMS UV URL ultra low-reflection

Front element protection. 95–100% transmission. Zero compromise.

A protective filter that truly doesn’t change the image — that’s a rare claim to back up. The Irix MMS UV URL ultra low-reflection is an upgraded version of the existing UV filter in the MMS ecosystem, featuring a new ultra low-reflection coating engineered for even lower reflectance and better optical neutrality. It shields the front element from dust, moisture, and scratches while maintaining visible light transmission at 95–100% with a flat, stable curve across the entire VIS range. The existing UV model remains available as a cost-effective alternative.

Designed with filmmakers and photographers in mind

Irix MMS UV URL ultra low-reflection is a protective filter created for photographers and filmmakers who expect more than basic front-element protection. It is designed to guard your lens against dust, scratches, and moisture while preserving the clarity, contrast, and color accuracy your work depends on. It is the ideal choice for creators who want to leave a protective filter on the lens at all times without affecting the character of the image.

One of the key strengths of this model is its ultra-low-reflection coating, which helps maintain a clean, neutral look across a wide range of shooting conditions. The filter delivers very high visible light transmission, with a stable transmission curve across the visible spectrum, helping preserve natural colors and strong contrast without introducing noticeable visual interference. At the same time, it effectively reduces UV transmission, reinforcing its protective function while supporting clean, dependable image quality.

This is also a filter engineered for demanding environments. Super Resistant glass and frame, combined with Irix precision manufacturing, deliver the optical and mechanical performance professionals expect. The hydrophobic surface helps repel water, grease, and dirt for easier cleaning, while the scratch-resistant finish improves durability during transport, frequent handling, and intensive day-to-day work. Just as importantly, laboratory testing confirms that this protection comes without measurable image degradation.

Key Benefits

• Ultra low-reflection coating — minimal light loss The URL (ultra low-reflection) coating is engineered for maximum transmission and minimum image interference. Visible light transmission sits at 95–100%, with a stable, flat response across the 380–780 nm range. In practice, this means the filter introduces no perceptible light loss, no color shift, and no contrast reduction — making it a viable permanent protective layer that stays on the lens without affecting your image.
• Effective UV reduction — outperforms Hoya UV UX II, Kenko Pro 1 Digital UV, and Marumi DHG The filter reduces ultraviolet transmission in the 300–380 nm range (dropping to approx. 40–60%), with the transition between UV blocking and full VIS transmission occurring around 380–400 nm. Lab-tested transmission comparisons with competing filters:
  • Hoya UV UX II: UV transmission 70–85% — Irix blocks UV significantly more effectively (40–60%)
  • Kenko Pro 1 Digital UV: UV transmission ~75–90% — Irix delivers noticeably better UV reduction
  • Marumi DHG Super Lens Protect: comparable VIS transmission, but Marumi begins passing UV below 350 nm — Irix suppresses UV more consistently
  • Hoya Fusion One UV and Irix UV Protector (screw-in version): perform better than the URL model in overall transmission

In the IR range (above 780 nm), transmission gradually decreases, indicating partial infrared suppression — an additional characteristic not offered by every UV filter.

• MTF: 89% with filter vs. 91% without — within margin of error (Canon EOS 5DS R, 50 MP) MTF analysis (iQ-Analyzer) showed a difference of just 2 percentage points: 89% with the filter vs. 91% without — tested on a 50-megapixel sensor that ruthlessly exposes even minimal optical imperfections. The lab report classifies this difference as within the margin of error and explicitly states that the filter can be used without concern for image degradation. Siemens star analysis confirmed no measurable loss of sharpness, resolution, or contrast.
• No impact on vignetting Imatest measurements: with filter sides -1.11 to -1.22 EV (mean -1.16 EV), corners -3.72 EV (corner mean -2.95 EV); without filter sides -1.1 to -1.21 EV, corners -3.71 EV (corner mean -2.94 EV). Difference at hundredths-of-EV level — effectively zero. The report’s conclusion: using the filter does not affect vignetting.
• Super Resistant glass and frame Tempered SR optical glass combined with a reinforced frame provides the mechanical durability required for intensive on-set and field work. This is a filter designed to stay on the lens permanently — without durability concerns.

Coatings: hydrophobic + oleophobic + scratch-resistant

Dual-sided NANO coating repels water, grease, and contaminants. The scratch-resistant surface improves safety during daily use, frequent cleaning, and transport.

Verified by lab tests

MTF (iQ-Analyzer): 89% with filter vs. 91% without — difference within margin of error. Siemens star analysis: no measurable loss of sharpness, resolution, or contrast. VIS transmission: 95–100%, stable and flat across 380–780 nm. UV reduction: transmission in 300–380 nm range reduced to approx. 40–60%. Vignetting (Imatest): no additional EV drop — values with and without the filter are virtually identical. Hydrophobic coating and scratch resistance verified in lab documentation.

Protect your optics without image loss. Irix MMS UV URL ultra low-reflection — a protective filter with 95–100% transmission, designed as a permanent layer for Irix Cine lenses.

Magnetic Mount System — fast mounting, 3.5mm profile

The MMS magnetic mount lets you attach the filter in a fraction of a second. The 3.5mm frame (4.94 mm total) maintains a compact profile and supports stackability with other MMS filters without vignetting risk.
