65-183 25 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 880nm
The 65-183 is a Bandpass Filter with a diameter of 25 mm, sourced from the renowned optical vendor, Edmund Optics. This filter is specifically designed for use with a central wavelength of 880nm, making it ideal for applications that require precise wavelength selection within this range.
The filter is characterized by its hard coating, which enhances its durability and resistance to wear and tear. The coating is applied to both the front and back surfaces, ensuring optimal performance from both sides. The coating type is EDM 65-122, a proprietary coating developed by Edmund Optics for enhanced optical performance.
The filter's geometry is defined by a thickness of 3.5 mm and a diameter of 25 mm. This combination of dimensions provides a robust and compact optical element that can be easily integrated into various optical systems.
The physical data of the filter includes a cut-on wavelength of 875nm and a cut-off wavelength of 885nm. These values define the range of wavelengths that the filter allows to pass, while blocking others. The central wavelength (CWL) of the filter is 880nm, indicating the wavelength at which the filter's transmission is maximum.
The filter's shape is defined as a Thin Lens, suggesting that it may have some degree of focusing power. However, this should be confirmed with the vendor or through further technical specifications.
