34-295 12.5 mm Dia. High Performance OD 4.0 Longpass Filter; t=1.5 mm 325nm

The 34-295 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 325 nm, making it ideal for applications that require the blocking of shorter wavelengths.

The filter's longpass characteristic is achieved through a precise cut-on wavelength of 325 nm, ensuring efficient blocking of unwanted light while allowing the desired wavelengths to pass through. The cut-off wavelength is 0 nm, indicating that all wavelengths shorter than the cut-on are effectively blocked.

The 34-295 filter features a circular shape and is made from UVFS Mal-1965 material, a choice that enhances its durability and performance in its intended applications. The filter's coating, applied to both the front and back surfaces, is designated as EDM 34-295, further contributing to its high-performance characteristics.

This filter is designed in a thin lens shape, offering versatility and ease of integration into various optical systems.
