HB600 HB610 HB630 HB640 HB650 HB670 HB685 HB700 HB720 Red Cut Off Optical Glass Filter

This series is designed for precise spectral control, blocking wavelengths below the cut-off point (e.g., HB600: 600±10nm) while allowing high transmittance in the target range (e.g., Tλ0≥88.7% at 680nm). Ideal for IR guidance, night vision, medical imaging, and laser applications. Customizable in size/shape, with excellent thermal stability (Tg up to 534°C) and chemical resistance. ISO-certified, ensuring reliability in harsh environments.
