The 64-656 is a 50 mm diameter Shortpass Filter, designed and manufactured by Edmund Optics. This filter is specifically engineered to transmit light below a certain wavelength while blocking light above that wavelength. The cut-off wavelength for this filter is 925nm, ensuring that only light with a wavelength of 925nm or less is transmitted.
This filter is part of the UVFS MAL-1965 material ID family, which is known for its high-quality optical properties. The filter has a thickness of 5mm, providing durability and stability. The base shape of the filter is circular, making it compatible with a wide range of optical systems.
The 64-656 filter features a Thin Lens shape, which is designed to minimize optical aberrations and distortions. This makes it ideal for applications that require high-precision optical performance, such as imaging, spectroscopy, and beam shaping.
The filter is coated on both the front and back surfaces with the EDM 64-642 coating. This coating enhances the filter's performance by reducing surface reflections and improving transmission efficiency. The coating also provides protection against environmental factors, such as dust and moisture, ensuring the longevity and reliability of the filter.
The 64-656 filter is currently in stock and available for purchase through the Edmund Optics website. The filter's catalog number is 64-656, and it can be found at the following link: https://www.edmundoptics.com/p/925nm-50mm-diameter-od-2-shortpass-filter/19362/.
