Overview

The Heliopan Type 8025 UV/IR Cut Filter is a specialized optical pass filter designed specifically for digital and video sensors lacking internal infrared and ultraviolet shielding. By passing clean daylight and blocking unwanted radiation, it eliminates the ghost images and color distortion caused by digital sensors' high sensitivity to invisible spectrums. The filter uses custom-calculated, micro-thin interference layers rather than absorption to block UV and thermal wavelengths with sharp cutoff edges. This restores rich color grading, heightens fine detail, and fixes the focus degradation that happens when infrared rays pass through standard lenses. Because it is visually clear, it requires no exposure compensation and serves as a reliable everyday lens protector.

Features

• Sharp Interference Blocking: Uses precisely engineered, reflective optical layers to cut off UV and thermal IR radiation at a steep angle.
• Noise and Blur Control: Reduces digital sensor color channel noise and eliminates the soft focus caused by uncorrected chromatic radiation.
• Pure Tonal Gradation: Enhances individual color separation and increases subject plasticity for entirely natural color reproduction.
• Zero Light Loss: Clear glass construction transmits the visible light spectrum completely, demanding a flat filter factor of 1.0.
• Premium Brass Housing: Stable brass cell limits mechanical stress on the glass and ensures smooth, bind-free threading on the camera lens.
• Permanent Shielding: Functions as a constant physical barrier against element damage without impacting visible color balance.
