64-685 25 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=3mm 925nm

The 64-685 is a Longpass Filter, part of the extensive catalog of optical elements provided by Edmund Optics. This filter features a circular shape and is designed with a 25 mm diameter and a thickness of 3 mm, making it suitable for various applications.

The filter is constructed with UVFS Mal-1965 material, a common choice for optical components due to its durability and optical properties. It is designed to transmit light with a wavelength of 588 nm and above, making it ideal for applications that require the blocking of shorter wavelengths.

The 64-685 filter is coated on both sides with EDM 64-678, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance by reducing surface reflections and improving transmission efficiency.

The filter's geometry is shaped as a Thin Lens, a design that minimizes optical aberrations and provides a clear, distortion-free image. This feature makes the 64-685 filter a versatile choice for a wide range of optical systems.
