86-673 50 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 850nm
The 86-673 is a Bandpass Filter, specifically designed for use in optical systems requiring a narrow wavelength transmission range. Sourced from Edmund Optics, this filter boasts a 50 mm diameter and a thickness of 3.5 mm, making it suitable for a wide range of applications.
The filter is designed to transmit light in the 850 nm range, with a Cut-On wavelength of 837.5 nm and a Cut-Off wavelength of 862.5 nm. This precise wavelength control is achieved through the use of a Hard Coating on both the front and back surfaces, which is identified as EDM 86-649. This coating enhances the filter's durability and resistance to environmental factors, ensuring reliable performance over time.
The filter's geometry is defined by its Circular shape and Thin Lens design, which allows for easy integration into various optical systems. The filter is currently in stock and available for immediate purchase through the provided weblink.
