35-880 25 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 270nm
The 35-880 is a Bandpass Filter, specifically designed for applications requiring a narrow wavelength transmission range. This filter, sourced from Edmund Optics, features a 25 mm diameter and a thickness of 3.5 mm, making it suitable for various optical systems.
The filter's primary function is to transmit light within a specific range, blocking other wavelengths. In this case, the cut-on wavelength is 265 nm, and the cut-off wavelength is 275 nm, with a center wavelength (CWL) of 270 nm. This precise wavelength selection is crucial in many applications, such as fluorescence microscopy, spectroscopy, and laser technology.
The 35-880 filter is made from UVFS Mal-1965 material, a common choice for ultraviolet (UV) applications due to its high transmittance and excellent thermal stability. The filter is hard-coated on both the front and back surfaces, enhancing its durability and resistance to environmental factors.
The filter's shape is defined as a Thin Lens, which is a lens with a thickness much smaller than its diameter. This shape allows for minimal optical aberrations and distortions, ensuring the quality of the transmitted light.
