The 85-915 is a Bandpass Filter, specifically designed for use in the optical spectrum around 1550nm. This filter, with a diameter of 50mm and a thickness of 3.5mm, is sourced from Edmund Optics, a leading vendor in the field of optical components. The catalog number for this item is 85-915.
The Bandpass Filter is designed to transmit light within a specific range of wavelengths, while blocking other wavelengths. In this case, the cut-on wavelength is 1525nm, and the cut-off wavelength is 1575nm, making this filter ideal for applications that require a narrow band of transmitted light around the central wavelength of 1550nm.
The filter is made from UVFS Mal-1965, a material specifically chosen for its optical properties in this wavelength range. The front and back surfaces of the filter are coated with EDM 85-891, a coating that enhances the filter's performance and durability.
The filter's geometry is defined by its diameter and thickness. With a diameter of 50mm, it is suitable for use in a wide range of optical systems. The thickness of 3.5mm is designed to provide structural rigidity while minimizing optical distortions.
The filter is shaped as a Thin Lens, which means it can focus light to a point, making it useful in imaging systems. The filter is currently in stock and available for immediate purchase, as indicated by its weblink status.
