The 64-651 Shortpass Filter is a circular filter with a 25 mm diameter and a thickness of 3 mm, sourced from Edmund Optics. This filter is designed to transmit light with wavelengths shorter than 1025 nm while blocking longer wavelengths, making it ideal for applications that require the removal of infrared light.
The filter is made from UVFS Mal-1965 material, a common choice for optical components due to its excellent transmission properties and durability. The front and back surfaces of the filter are coated with EDM 64-644, a coating that enhances the filter's performance and longevity.
The 64-651 filter is shaped as a Thin Lens, which is beneficial in applications where a flat surface is not preferred. This shape allows the filter to be used in a variety of setups, increasing its versatility.
According to the vendor's information, the filter is currently in stock and can be purchased directly from the Edmund Optics website. The item's catalog number is 64-651, and it is listed under the Filters category.
