89-758 42 mm Dia. Mounted NUV Machine Vision Imaging Filter; t=1.75 mm 325nm
The 89-758 is a 42 mm diameter mounted NUV (Near Ultraviolet) Machine Vision Imaging Filter, with a thickness of 1.75 mm, specifically designed for use with a central wavelength of 325nm. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for purchase through their website.
The filter is a Bandpass type, which means it allows light to pass through a specific range of wavelengths while blocking out other wavelengths. In this case, the cut-on wavelength is 277.5nm, and the cut-off wavelength is 372.5nm. This makes the filter ideal for applications that require the isolation of specific ultraviolet light wavelengths.
The filter is made from UVFS (Ultraviolet Fused Silica), a material with excellent transmittance in the ultraviolet region, ensuring high-quality imaging. The filter's geometry includes a diameter of 42mm and a thickness of 1.75mm, making it suitable for use in various imaging systems.
The 89-758 filter features a Thin Lens shape, which is designed to minimize optical aberrations and distortions, further enhancing the quality of the images produced. The filter's coating, EDM 89-753, is applied to both the front and back surfaces, providing additional protection and enhancing the filter's performance.
