CRI-16 Color Rendering Improvement Filter

CRI-16 is a colour-rendering (CRI/TLCI) filter that warms and smooths spiky LED/HMI spectra—cutting deep blue and yellow-green while preserving a cyan window and strong long-red for higher CRI/TLCI, better R9, and natural skin tones.

• Function: CRI/TLCI improvement; reduces deep blue & yellow-green, preserves cyan & long-red
• Deep-blue control: High ~88–90 % @ 390–420 nm → ~20–22 % T near 450–460 nm
• Cyan window: Rebounds to ~88–90 % T around 490–505 nm
• Yellow-green shaping: Broad dip 520–610 nm; minimum ~28–32 % T near 545–560 nm
• Long-red throughput: Rise to ~93–95 % T by 650–720 nm; holds ~92–94 % toward 780 nm
• Construction & format: Durable dielectric on Borofloat®, Eagle XG, D263 T, or soda-lime • 5–450 mm • 0.21–3.8 mm • options: rear-AR & slight wedge
