The NIR-Block Filter



The NIR-Block provides those UV photographers who use stacks of ionic filters the opportunity to achieve a new maximum in NIR (Near-Infrared) blocking while still enjoying excellent UV transmission. In the NIR-Block we have exceeded the UV transmission of the Schott S8612 while also providing significantly greater out-of-band blocking. The NIR-Block is a single piece of a proprietary glass recipe, 3.00mm thick. The 52mm mounting ring has suffient depth to permit other 52mm screw-on filters to be stacked above or below the NIR-Block. Extreme near-Infrared blocking makes ultraviolet photography possible even in conditions such as rainy days, when the amount of UV is low, the percentage of NIR wavelengths may be high, and a long exposure time is necessary.

The NIR-Block is expected to be popular worldwide among scientific, technical, and art photographers. The NIR-Block with its exceptional out-of-band blocking, high-speed, low cost, and durability will enable even more photographers to enjoy the world of UV reflectance photography.

The NIR-Block is provided in a custom, black 52mm threaded ring
