87-868 25 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 1425nm

The 87-868 is a Bandpass Filter, specifically designed for use in optical systems requiring a narrow bandwidth of 50nm centered at 1425nm. This filter, sourced from Edmund Optics, is characterized by a circular shape with a diameter of 25mm and a thickness of 3.5mm.

The filter is constructed from UVFS Mal-1965 material, a common choice for its optical properties and durability. It features hard coating on both the front and back surfaces, denoted as 'edm 87-855', which enhances its resistance to wear and environmental factors.

The filter's physical data includes a cut-on wavelength of 1400nm and a cut-off wavelength of 1450nm, with a central wavelength (CWL) of 1425nm. This makes it ideal for applications that require precise wavelength selection and rejection of unwanted spectral regions.

The 87-868 filter is designed in the shape of a thin lens, optimized for minimal optical aberrations and distortions. It is currently in stock and available for immediate use or integration into your optical system.
