Color Temperature Filters

Our Color Temperature Filters provide precise white-balance control by shifting the correlated color temperature (CCT) of any light source. Whether you need to cool down tungsten to match daylight or warm up LEDs to blend with incandescent fixtures, these filters deliver accurate, repeatable color shifts measured in mireds or kelvins. This level of control is essential for technical applications like camera calibration, LED binning, and broadcast lighting—where mismatched sources create color inconsistencies that cameras expose unforgivingly. For creative work, the same filters transform the mood of any scene, simulating everything from crisp arctic daylight to the warm glow of late afternoon sun, all without disposable gels that fade and warp under heat.

Built with hard-dielectric coatings on premium optical glass, our Color Temperature Filters withstand temperatures up to 450°C and pass MIL-M-13508C environmental testing for proven durability. Choose from our CTB (Blue Shift) line to move toward cooler daylight tones, or our CTO (Orange Shift) line for warmer amber hues—each available in full strength down to precise fractional increments like ½, ¼, and ⅛. We custom-manufacture any size or shape, from small chips for sensor assemblies to large panels for lighting fixtures, with optional anti-reflective or protective coatings.
