12-256 25 mm Dia. Hard Coated Laser Line Longpass Filter 808nm

The 12-256 is a 25 mm diameter Longpass Filter, specifically designed for use with 808nm laser lines. This filter is sourced from Edmund Optics, a renowned vendor in the optical industry, and is available for purchase through their website. The filter is currently in stock, ensuring quick and efficient delivery for your project needs.

The filter is made from UVFS Mal-1965 material, a choice that enhances its performance and durability. It features a circular base shape, a geometry that is commonly used in optical applications due to its uniformity and ease of integration. The filter has a thickness of 3.5mm, providing sufficient structural integrity while maintaining minimal impact on the optical path.

The 12-256 filter is designed to cut on at 808nm, meaning it allows transmission of wavelengths above this value while blocking those below. The cut-off wavelength is 0nm, indicating that it blocks all wavelengths in the ultraviolet range. This makes it ideal for applications where 808nm laser lines are used, such as in laser spectroscopy, bio-imaging, and material processing.

Both the front and back surfaces of the filter are coated with EDM 12-256, a coating that enhances the filter's performance and longevity. The filter's shape is thin lens, a design that minimizes optical aberrations and ensures accurate light transmission.
