15-446 12.7 mm Dia. Dielectric Coated Colored Glass Replacement Longpass Filter 550nm

The 15-446 is a 12.7 mm diameter colored glass replacement longpass filter with a cut-on wavelength of 550nm, available from Edmund Optics. This filter is designed for use in optical systems where longpass filtering is required, with a specified cut-on wavelength that allows for efficient transmission of longer wavelengths while effectively blocking shorter wavelengths.

The filter is made of UVFS Mal-1965 material, which is known for its excellent optical properties and durability. It features a circular base shape and a thin lens shape, with a thickness of 1.1mm, making it suitable for use in compact optical systems. The filter's geometry is designed to provide excellent optical performance, with a diameter that ensures sufficient light gathering while minimizing vignetting.

The 15-446 filter is coated on both the front and back surfaces with EDM 15-446 coating. This coating enhances the filter's performance by reducing surface reflections and improving transmission. The coating also provides protection to the filter's surface, reducing the risk of damage during handling and operation.

The filter is currently in stock and available for purchase through the Edmund Optics website.
