84-745 25 mm Dia. Hard Coated High Performance OD 4.0 Longpass Filter; t=3 mm 575nm
The 84-745 is a high-performance longpass filter, measuring 25 mm in diameter and 3 mm in thickness, offered by Edmund Optics. This filter is designed to transmit light at wavelengths above 575 nm, making it suitable for applications that require the removal of shorter wavelengths.
The filter features a hard coating on both the front and back surfaces, enhancing its durability and resistance to wear and tear. This coating also helps to reduce reflection, thereby improving the overall transmission efficiency of the filter.
The 84-745 filter is cut on at 575 nm, meaning that it starts to transmit light at this wavelength. The cut off is 0, indicating that it allows all wavelengths longer than 575 nm to pass through. This broad transmission range makes it a versatile tool for a wide range of optical applications.
The filter is designed in a thin lens shape, which not only contributes to its compactness but also minimizes optical aberrations. It is made from UVFS Mal-1965, a material known for its excellent optical properties.
