Our Spectral Correction Filters are engineered to refine and enhance the color quality of your light source. The Color Rendering Improvement line boosts the CRI of LEDs and other artificial sources, bringing skin tones and product colors closer to how they appear under natural daylight—essential for broadcast studios, retail displays, and any environment where accurate color perception matters. The Minus Green series targets the unwanted green spike common in fluorescent and some LED fixtures, delivering a cleaner, more balanced spectrum for cinema, photography, and medical imaging applications.
Like all our optical filters, these are built for demanding professional use. Durable hard-dielectric coatings on premium optical glass withstand temperatures up to 450°C and meet MIL-M-13508C environmental standards for long-term reliability. We custom-manufacture any size or shape you need, with options for anti-reflective or protective coatings. Whether you require a subtle spectral tweak or a comprehensive color-quality overhaul, share your target specifications and we'll engineer a precise solution tailored to your application.
