34-298 12.5 mm Dia. High Performance Longpass Filter with 350 nm Cut-on Wavelength
The 34-298 is a high-performance longpass filter, boasting a 12.5 mm diameter and a thickness of 1.5 mm. This filter, sourced from the reputable vendor Edmund Optics, is designed to transmit light with wavelengths longer than 350 nm, making it ideal for applications that require the removal of shorter wavelengths.
The filter is constructed from UVFS Mal-1965, a material specifically chosen for its optical properties. It features a circular base shape, ensuring easy integration into various optical systems. The 34-298 filter is coated on both the front and back surfaces with EDM 34-298, a coating that enhances its performance and durability.
This filter is designed in the shape of a thin lens, optimizing its light-bending capabilities. The cut-on wavelength is set at 350 nm, meaning it begins to transmit light at this wavelength and beyond. The cut-off wavelength is 0 nm, indicating that it transmits all wavelengths longer than the cut-on point.
The 34-298 filter is currently in stock and available for purchase through the Edmund Optics website. For more information, users can refer to the provided catalog number and weblink.
