Our Color Rendering Improvement Filters enhance the spectral quality of artificial light sources, boosting their ability to render colors accurately. Many LEDs and discharge lamps sacrifice color fidelity for efficiency, resulting in washed-out skin tones, dull fabrics, and products that look different under store lighting than in natural daylight. These filters fill in the spectral gaps, raising CRI and R9 values to bring colors to life—essential for retail displays, broadcast studios, museums, and any application where true-to-life color perception drives decisions and experiences.

Engineered for professional reliability, these filters feature durable hard-dielectric coatings on high-quality optical glass, rated for temperatures up to 450°C and tested to MIL-M-13508C environmental specifications. They integrate seamlessly into existing lighting systems, offering a cost-effective way to upgrade color quality without replacing fixtures. We custom-cut any size or shape and can tailor the spectral enhancement to complement your specific light source—whether a high-efficiency LED panel or a legacy fluorescent installation. Share your current spectrum data or target CRI goals, and we'll engineer a filter solution that transforms your lighting performance.
