825nm 12.5mm, Ultra-Thin OD4 Longpass Filter

Product Details Ultra-thin 300µm Construction OD ≥4.0 Blocking and >85% Average Transmission Lightweight and Scratch Insensitive Everix Ultra-Thin OD 4.0 Longpass Filters are constructed from layers of ultra-thin polymers and dyes that deliver the same performance as thick traditional filters but in a compact 300µm, flexible filter design. These filters cover wavelengths from the visible to the near infrared (NIR) regions and offer rejection levels meeting optical densities ≥ 4.0 while providing >85% average transmission.Custom bandpass filters can be created by combining these filters with the Everix Ultra-Thin OD4 Shortpass Filters to assist with the elimination of stray light. Everix Ultra-Thin OD 4.0 Longpass Filters are ideal for a variety of weight sensitive applications in medical technology, automation, and autonomous vehicles. Everix’s proprietary ultra-thin filter technology yields filters which are less sensitive to scratches and other imperfections than comparable coated filters.
