HMG-5 Minus Green Filter

HMG-5 stands as the premium choice for mission-critical color correction, delivering 90.1 % average transmission across the visible spectrum - exceptional for light-critical workflows. This high-transmission half minus green filter maintains blue at 92.2 %, green at 86.4 %, and red at 95.0 %, achieving gentle minus green action while preserving maximum system luminance. The filter's peak transmission of 95.8 % at 682 nm and minimal variation across the visible range make it ideal for applications where every photon counts. Superior flux retention combined with reliable green suppression in the 78-86 % range defines its premium positioning.

Key Advantages

• Exceptional Light Transmission - 90.1 % average visible transmission with peak 95.8 % delivers maximum luminance to sensor or eye - critical for low-light production and high-speed cinematography requiring fast lens apertures
• Balanced Color Preservation - Blue 92 %, green 86 %, red 95 % creates warm-neutral correction without introducing magenta or cyan casts, yielding natural-looking results with minimal post-production adjustment
• Subtle Yet Effective Green Reduction - Gentle suppression curve minimizes overcorrection when stacking multiple filters or using with cooler color temperature sources, preventing the greenish-amber appearance common with aggressive filters
• Hard-Oxide Ion-Assisted Coating - Multilayer dichroic coating engineered for durability through repetitive mounting, cleaning, and field deployment in professional production environments
• Custom Format Options - Supplied in round, square, free-form blanks spanning 5 mm to 450 mm with 0.21-3.8 mm thicknesses on Borofloat, soda-lime, Schott D263 T, or Corning Eagle XG substrates

Typical Applications

• High-End Broadcast & Cinema - Preserve critical luminance in premium productions where sensor performance and skin tone fidelity demand maximum light throughput with precise green control
• Commercial & Advertising Film - Maintain color saturation and exposure latitude when shooting under standardized studio fluorescent grids combined with tungsten fill and daylight bouncing
• Nature & Wildlife Documentary - Correct outdoor mixed-lighting conditions - tungsten reflectors near dappled forest light, dawn shoots with fluorescent camp equipment - while preserving native color nuance
• Medical & Surgical Imaging - Achieve neutral white balance in operating theaters illuminated by surgical LED headlights, overhead halogen, and fluorescent monitoring arrays without color fringing
• Industrial & Scientific Photography - Support precision imaging in research labs where specimen color accuracy and minimal light loss are equally critical - from mineralogy to materials testing
