66-234 25 mm Dia. Hard Coated High Performance OD 4.0 Longpass Filter; t=3 mm 750nm
The 66-234 is a high-performance longpass filter, boasting a 25 mm diameter and a thickness of 3 mm, sourced from the reputable vendor, Edmund Optics. This filter is designed with a hard coating, enhancing its durability and longevity, making it an ideal choice for various optical applications.
The filter's primary function is to allow light transmission above a specified wavelength, while blocking or attenuating light below this cut-on wavelength. In this case, the 66-234 is designed to cut on at 750nm, making it suitable for applications where longer wavelengths are of interest.
The 66-234 features a circular shape, a standard in many optical systems due to its ease of alignment and integration. It is made from UVFS Mal-1965, a material known for its optical properties and compatibility with various optical systems.
The filter's coating is another notable feature. Both the front and back surfaces are coated with EDM 66-226, a coating that enhances the filter's performance and durability. This coating helps to reduce surface reflections and increase transmission, thereby improving the overall efficiency of the optical system.
The 66-234 is designed in a thin lens shape, which is beneficial for applications where space is a constraint. This filter is currently in stock and available for immediate use. For more information, users can refer to the provided weblink.
