86-077 50 mm Dia. Hard Coated High Performance OD 4.0 Longpass Filter; t=5 mm 775nm
The 86-077 is a high-performance longpass filter, measuring 50 mm in diameter, manufactured by Edmund Optics. This filter is designed to transmit light at wavelengths above 775 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. The coating also helps to reduce reflection, thereby improving the overall transmission efficiency of the filter.
The 86-077 filter has a thickness of 5 mm, which is relatively thin compared to other filters in its class. This thin design not only reduces the weight of the filter but also minimizes optical aberrations, resulting in improved image quality.
The filter is made from UVFS Mal-1965, a material known for its excellent optical properties. It has a cut-on wavelength of 775 nm, meaning it begins to transmit light at this wavelength. The cut-off wavelength, on the other hand, is 0 nm, indicating that it transmits all wavelengths longer than 775 nm.
The 86-077 filter is designed in a thin lens shape, which is ideal for applications that require a compact and lightweight optical component. It is currently in stock and available for purchase through the Edmund Optics website.
