The Maxspect TrueReef Filter Lens for iPhone is an advanced photographic accessory designed specifically for saltwater reef aquariums. Unlike standard acrylic filters that often overcorrect lighting, this innovative lens ensures your iPhone captures the true vibrancy and brilliant fluorescent glow of your corals. It selectively reflects harsh high-energy visible blue light while carefully preserving the delicate near-UV fluorescence, resulting in balanced and authentic photos. This unique lens features an innovative blue monomer coating that actively reflects a portion of HEV light, instead of merely absorbing it, which is key to maintaining the crucial near-UV glow around 420 nm and below. This technology delivers true-to-life color without a flat, oversaturated look, preserves vivid coral fluorescence and intricate detail, and creates cleaner contrast against the background rockwork. Maxspect offers two distinct options: the Gouda Lens (yellow) for subtle correction allowing some violets and blue, and the Sunset Boulevard Lens (orange) for setups with heavy blue lighting, filtering out all violet, blue, and cyan. This product is perfectly suited for any saltwater reef aquarium enthusiast who desires to accurately document and share the stunning beauty of their tank using their iPhone. It's an essential tool for hobbyists frustrated by traditional camera filters that strip away the natural fluorescence and vibrant hues of their corals, providing an unparalleled solution for capturing the dynamic and colorful reality of their reef system.
