TMG-3308 Minus Green Filter

TMG-3308 delivers the most aggressive minus green action in the lineup, suppressing green to just 47.6 % average while red remains strong at 83.5 %. This deep minus green filter targets heavy fluorescent and discharge lamp sources where standard correction proves insufficient. Peak transmission of 91.4 % at 702 nm combined with substantial UV suppression at 49.3 % creates a compound effect - green elimination plus ultraviolet rejection - necessary for severely green-dominant light sources. Blue moderate at 67.5 % and the pronounced yellow dip at 53.0 % define TMG-3308 as the choice for extreme color correction scenarios where conventional filters underperform.

Key Advantages

• Heavy-Duty Green Suppression - Reduces green to 47.6 % - a 35+ percentage-point cut from red - for severe overcorrection of old mercury vapor, high-output fluorescent, and problematic discharge lamp arrays
• Yellow-Green Notch Elimination - Deep dip across the 540-580 nm yellow-green zone addresses the spectral heartland of fluorescent phosphor output, eliminating the characteristic green-yellow cast entirely
• UV Rejection Bonus - Blocks approximately 50 % of ultraviolet at 380 nm, removing sensor noise and false color channels alongside green dominance in combined UV-green-heavy sources
• Hard-Oxide Ion-Assisted Coating - Heavy-duty multilayer dichroic construction resists thermal shock and environmental stress from high-intensity discharge sources and aggressive field handling
• Custom Format Options - Supplied in round, square, free-form blanks ranging 5 mm to 450 mm diameter, 0.21-3.8 mm thickness on Borofloat, soda-lime, Schott D263 T, or Corning Eagle XG substrates

Typical Applications

• Industrial Facility Correction - Neutralize dominant green casts in warehouses, factories, and industrial spaces lit by high-output T8 fluorescent systems, metal halide, or sodium vapor arrays
• Institutional Environments - Correct hospitals, schools, and office buildings where dense fluorescent ceiling grids create overwhelming green-yellow ambient light for video documentation
• Outdoor Discharge Correction - Compensate for temporary or permanent mercury-vapor and high-pressure sodium street lighting on exterior event coverage, construction documentation, or urban cinematography
• Machine Vision in Legacy Facilities - Achieve neutral white balance in factory quality control and inspection systems illuminated by old mercury or sodium discharge arrays resistant to replacement
• Extreme-Condition Video Documentation - Support ENG, documentary, and emergency response videography in poorly lit institutional, industrial, or disaster environments where standard corrections fail
