86-961 50 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 425nm

The 86-961 is a Bandpass Filter, specifically designed for use in optical systems where precise wavelength selection is required. This filter, sourced from Edmund Optics, features a circular shape with a diameter of 50 mm and a thickness of 3.5 mm. The filter is made from UVFS Mal-1965 material, ensuring high-quality performance and durability.

The 86-961 filter is designed to pass light in the 425nm wavelength range, while blocking light at other wavelengths. This is achieved through the use of a hard coating on both the front and back surfaces, specifically the EDm 86-937 coating. The cut-on wavelength is 400nm, and the cut-off wavelength is 450nm, providing a narrow 50nm bandwidth for precise wavelength selection.

This filter is suitable for use in a variety of applications, including fluorescence microscopy, spectroscopy, and other applications where precise wavelength control is necessary. The filter is currently in stock and available for purchase through the Edmund Optics website.
