HOYA LA/LB Light Balancing Filters for Industrial Applications
HOYA CANDEO LA and LB series light balancing filters are precision color temperature correction filters designed for industrial imaging, machine vision, and scientific research. LA series shifts color temperature toward warmer tones (positive mired shift), while LB series shifts toward cooler tones (negative mired shift). Standard 50x50mm square format.
Key Features
- Precise mired shift values for accurate color temperature control
- LA series: warm correction (positive mired shift)
- LB series: cool correction (negative mired shift)
- Precision optical glass construction
- Standard 50x50mm square format for industrial applications
- Suitable for machine vision, colorimetry, and scientific imaging
