86-742 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 685nm
The 86-742 is a Bandpass Filter, specifically designed by Edmund Optics with a diameter of 50 mm and a thickness of 3.5 mm. This filter is part of the UVFS MAL-1965 material ID family, which ensures high-quality performance and durability.
The filter's primary function is to allow light transmission within a specific range of wavelengths, while blocking other wavelengths. In this case, the Cut-On wavelength is 680nm, and the Cut-Off wavelength is 690nm, with a Central Wavelength (CWL) of 685nm. This makes it ideal for applications that require a narrow band of light around this wavelength.
The 86-742 filter is hard coated on both the front and back, with the coating type EDm 86-734. This coating enhances the filter's durability and resistance to environmental factors, ensuring reliable performance even in challenging conditions.
The filter's shape is that of a Thin Lens, which is beneficial in applications where minimal optical interference is required. This filter is currently in stock and available for immediate purchase through the provided weblink.
