The 14-078 is a 50 x 50 mm SCHOTT NG1 Gray Glass Neutral Density Color Filter, designed for use in the 400-700nm wavelength range. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for purchase through their website.
The filter is of the 'Color Glass' subtype, which means it is designed to absorb specific wavelengths of light while transmitting others. In this case, the filter is gray, indicating that it absorbs light evenly across the visible spectrum. This makes it ideal for applications where a uniform reduction in light intensity is required.
The filter has a rectangular base shape, with a thickness of 3mm, making it suitable for use in a variety of optical systems. The 'Thin Lens' shape indicates that the filter is designed to minimize optical aberrations, ensuring clear and accurate transmission of light.
The physical data of the filter specifies that it is 'cut on' at 400nm and 'cut off' at 700nm. This means that the filter begins absorbing light at 400nm and stops absorbing at 700nm. This wide range makes it suitable for use in a variety of applications, from photography to scientific research.
The filter is coated on both the front and back surfaces with the 'edm 14-078' coating. This coating is designed to enhance the filter's performance and durability, ensuring that it maintains its optical properties even under harsh conditions.
