Color Correction Filters

Our Color-Correction Filters solve the problem of mismatched light sources by providing precise white-balance control. The CTB (Color Temperature Blue) line creates a cooler, blue shift, while the CTO (Color Temperature Orange) line produces a warmer, amber tone. This is vital for technical applications like LED binning, camera calibration, and on-set cinema lighting to match different light engines. Creatively, these same durable filters can be used in lighting fixtures to simulate everything from arctic daylight to a fiery sunset, replacing the need for disposable gels.

Built with tough, hard-dielectric coatings on your choice of quality glass, these filters are heat-resistant up to 450°C and pass MIL-M-13508C environmental tests for reliability. We custom-cut any size or shape—from 5 mm chips to 450 mm panels—with optional anti-reflective or protective layers. The customization is exceptionally precise, allowing for specific fractional strengths (like CTO ½) or custom tuning to a unique LED source. Simply tell us your target color shift (ΔCCT), and we’ll engineer and deliver your custom solution quickly.
