87-858 12.5 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 1575nm
The 87-858 is a Bandpass Filter with a diameter of 12.5 mm and a thickness of 3.5 mm, sourced from the reputable optical components vendor, Edmund Optics. This filter is specifically designed for a central wavelength (CWL) of 1575nm, with a cut-on wavelength of 1550nm and a cut-off wavelength of 1600nm.
The Bandpass Filter is a type of optical filter that allows only a specific range of wavelengths to pass through it, while blocking other wavelengths. This particular filter is hard coated on both the front and back surfaces with the coating code "edm 87-858". The hard coating enhances the durability and longevity of the filter, making it suitable for various applications.
The filter is designed in a Thin Lens shape, which is a type of lens that is characterized by a short focal length compared to its overall diameter. This shape allows for efficient light transmission and minimal distortion.
The 87-858 is available for purchase directly from the Edmund Optics website, where it is listed as being in stock. The product's webpage also provides additional information and specifications, which can be accessed via the provided weblink.
