86-738 25 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 685nm

The 86-738 is a Bandpass Filter, specifically designed for applications requiring a narrow wavelength transmission range. Sourced from Edmund Optics, this filter boasts a 25 mm diameter and a thickness of 3.5 mm, making it suitable for various optical systems.

The filter's primary function is to transmit light in the center wavelength (CWL) of 685nm, while effectively blocking light at wavelengths outside this range. The cut-on wavelength is 680nm, and the cut-off wavelength is 690nm, ensuring a tight 10nm bandpass. This feature is crucial in applications such as fluorescence microscopy, spectroscopy, and laser technology, where precise wavelength control is essential.

The 86-738 filter is hard coated on both the front and back surfaces, enhancing its durability and resistance to environmental factors. The coating material is UVFS MAL-1965, which is known for its high-quality performance and reliability. The filter's shape is a Thin Lens, further expanding its compatibility with various optical setups.
