67-861 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 930nm

The 67-861 is a 25 mm diameter mounted bandpass interference filter, designed and manufactured by Edmund Optics. This filter is specifically centered at 930nm, with a full width at half maximum (FWHM) of 10nm, making it ideal for applications that require narrowband transmission. The filter features a thin lens shape, ensuring minimal optical aberrations and distortions.

The filter's physical dimensions include a diameter of 25mm and a thickness of 5.9mm, providing a robust and compact design suitable for various optical systems. The cut-on wavelength is 925nm, and the cut-off wavelength is 935nm, further enhancing its narrowband transmission properties.

The 67-861 filter is coated with EDM 67-794 on both the front and back surfaces. This coating provides excellent optical performance, including high transmission and low reflectance, ensuring optimal light propagation through the filter.

The filter is available for purchase through the Edmund Optics website, and the link provided in the item data indicates that it is currently in stock, ensuring quick delivery times. This filter is part of the UVFS MAL-1965 material ID, further specifying its properties and applications.
