48-624 12.5 mm Dia. UV-VIS Metallic Based Neutral Density Filter; OD 2.5 250-700nm
The 48-624 is a Neutral Density Filter with a 12.5 mm diameter, sourced from the reputable optical components vendor, Edmund Optics. This filter is specifically designed for use in the UV-VIS spectrum, with a wavelength of 588 nm, making it suitable for a wide range of optical applications that require light absorption and neutral density.
The filter features a Metallic Based coating on both the front and back, denoted as 'edm 48-624'. This coating provides an Optical Density (OD) of 2.5, which corresponds to a transmission of approximately 0.67% over the 250-700nm wavelength range. This high OD value makes the filter ideal for applications requiring significant light reduction, such as high-intensity laser applications or high-power LED systems.
The filter has a Thin Lens shape, with a thickness of 1.5 mm, which helps to minimize optical aberrations and ensures easy integration into optical systems. The circular geometry of the filter, with a 12.5 mm diameter, is another advantage, providing a large aperture for efficient light collection while maintaining a compact form factor.
