67-299 25 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=3mm 1200nm
The 67-299 is a Longpass Filter, part of the extensive catalog offered by Edmund Optics. This filter, with a 25 mm diameter and a thickness of 3mm, is designed for use in optical systems that require long-pass filtering at 1200nm.
The filter is made from UVFS Mal-1965, a material specifically chosen for its optical properties. It features a traditional coating on both the front and back surfaces, denoted as 'edm 67-296'. This coating enhances the filter's performance and durability.
The 67-299 filter is designed to cut on at 1200nm, allowing light of longer wavelengths to pass through while blocking shorter wavelengths. The cut-off point is 0nm, indicating that it allows all wavelengths longer than 1200nm to pass.
The filter's shape is that of a thin lens, making it suitable for use in a wide range of optical applications. The catalog number for this item is 67-299, and it is currently in stock, as indicated by its weblink status. For more information, users can visit the provided weblink.
