85-890 12.5 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 1500nm
The 85-890 is a Bandpass Filter, specifically designed by Edmund Optics, with a diameter of 12.5 mm and a thickness of 3.5 mm. This filter is hard coated, ensuring durability and longevity, and has an OD (Outside Diameter) of 4.0.
The Bandpass Filter is designed to transmit light within a specific range of wavelengths, while blocking other wavelengths. The 85-890 is designed to transmit light at a center wavelength (CWL) of 1500nm, with a cut-on wavelength of 1475nm and a cut-off wavelength of 1525nm. This makes it ideal for applications that require the precise transmission of light within this range.
The filter features a coating on both the front and back surfaces, denoted as 'edm 85-890'. This coating is designed to enhance the performance of the filter, providing a high level of transmission and blocking unwanted wavelengths.
The 85-890 is shaped as a Thin Lens, which is a type of lens with a small thickness compared to its diameter. This makes it suitable for use in a wide range of optical systems, where space and weight are critical factors.
The filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its weblink status. For more information, users can refer to the provided weblink.
