Optical Filters Ircut Filter (IR-Cut) for CCD/CMOS Image Sensors

Optical Filters Ircut Filter (IR-Cut) for CCD/CMOS Image Sensors. reflects and cuts off the near infrared light: Effectively blocks unwanted Near-Infrared (NIR) light 700-1100nm from reaching the CMOS/CCD sensor, completely eliminating color shifts, purple fringing. Ultra-High Transmittance: Achieves over $95\%\text{--}98\%$ average transmittance in the visible spectrum ($400\text{--}650\text{ nm}$), ensuring bright, clear images even in low-light environments. Advanced Vacuum Coating Technology (IAD / Ion-Assisted Deposition): Multi-layer dielectric hard coatings provide excellent resistance to heat, humidity, corrosion, and thermal shock. High Customizability & Flexible Design:Tailored Wavelengths: Customizable cut-off points (630nm, 650 nm, 680 nm, etc.) and bandpass options (e.g., dual-passband 850nm 940nm for day/night vision switch. Elimination of IR Focus Shift: Enhanced Image Sharpness: Prevents chromatic aberration caused by infrared wavelength deflection, maintaining sharp focus across the entire sensor frame. High Visible Transmission & Optical Precision: Features a steep slope at the cut-off wavelength (e.g., 650nm+- 5nm to precisely separate visible light from infrared without signal overlap. Superior Color Fidelity & True-to-Life Imaging: Human Eye Emulation: Restores real-world color balance, delivering crisp, natural, and accurate visual performance. High Environmental Durability: Multi-layer dielectric hard coatings provide excellent resistance to heat, humidity, corrosion, and thermal shock. Scratch & Wear Resistant: Meets stringent industrial optical standards for hardness and surface quality (e.g., ISO / MIL-SPEC). Substrates Available: Blue Glass (absorptive), Optical Glass (BK7 / K9), Quartz / Fused Silica, or Sapphire.
