The 54-736 is a 54 mm diameter, 5 mm thick absorptive neutral density filter, sourced from the renowned optical components vendor, Edmund Optics. This filter is designed to uniformly reduce the intensity of incident light, without altering its color composition, across the spectral range of 400-700 nm.
The filter features a circular geometry, with a 0.6 OD (optical density) rating, indicating a 50% transmission of light. This makes it suitable for applications requiring moderate light reduction, such as in photography, beam attenuation, or laser applications.
The filter is coated with EDM 59-167 on both the front and back surfaces, a coating known for its absorptive properties, further enhancing its neutral density capabilities. The filter is also designed in a thin lens shape, minimizing optical aberrations and ensuring high-quality imaging.
