QMG Minus Green Filter

QMG is a minus-green (magenta-balance) broadband filter that trims the mid-green while keeping output high in blue and long-red. Transmission sits ~85–90% from ~410–500 nm, eases through a controlled green dip of ~72–75% around ~540–560 nm, then climbs to ~90–92% from ~610–680 nm with a second high spot ~94–95% near ~720–740 nm. Toward the band edge it tapers to ~55–60% by ~780 nm for a gentle warm finish.

Key advantages

• Minus-green tuning — a targeted notch across ~540–560 nm neutralizes LED/fluorescent “plus-green” without pushing scenes overly magenta.

• High red throughput — ~90–95% T from ~610–740 nm preserves skin-tone warmth and exposure headroom.

• Crisp, clean blues — ~85–90% T from ~410–500 nm keeps whites bright and blues saturated.

• Smooth, low-ripple curve — predictable colour move across dimming levels and fixture types.

• Built for production — hard dielectric stack resists abrasion and humidity; optional rear-surface AR and slight wedge suppress ghosts/flare.

• Custom formats — Borofloat®, Eagle XG or D263 T (0.21–3.8 mm) for high-temp to ~450 °C; economical soda-lime for ≤150 °C. Custom sizes 5–450 mm.

Typical applications

• Cinema/TV lighting — lift TLCI/CRI by shaving mid-green while keeping red channel energy high.

• Photography & events — neutralize green spill from mixed LED/fluorescent rigs for natural skin tones.

• Architectural & stage — correct ambient greenish cast while maintaining punch and clarity.

• Retail & museum — more accurate product/art colour with minimal light loss.

• Machine vision — balance channels when green overwhelms red-critical features.
