87-842 50 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 1350nm

The 87-842 is a Bandpass Filter, specifically designed for use in optical systems requiring a narrow passband around the 1350nm wavelength. This filter, sourced from Edmund Optics, features a circular geometry with a 50mm diameter and a thickness of 3.5mm.

The Bandpass Filter is characterized by its physical data, with a cut-on wavelength of 1337.5nm and a cut-off wavelength of 1362.5nm, ensuring a tight bandpass of 25nm centered at 1350nm. This precise wavelength control makes the 87-842 ideal for applications demanding high spectral purity and rejection of out-of-band wavelengths.

The filter's front and back surfaces are coated with EDM 87-818, a hard coating that enhances durability and resistance to environmental factors, ensuring reliable performance and a long lifespan. The Thin Lens shape of the filter facilitates easy integration into various optical systems, while maintaining minimal optical aberrations.
