900DIJ25 25 mm Dia. Standard Interference Bandpass Filter 900nm
The 900DIJ25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 900nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.
The filter is of the Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking out unwanted light from other spectral regions. This particular model has a cut-on wavelength of 895nm and a cut-off wavelength of 905nm, ensuring a narrow and precise bandpass. The cut-on and cut-off wavelengths are crucial parameters in determining the filter's performance and suitability for specific applications.
The 900DIJ25 is made from UVFS Mal- 1965, a material known for its optical properties and durability. The filter has a thickness of 6.1mm, which contributes to its robustness and stability. The geometry of the filter is circular, a common shape for optical components due to its ease of integration into various systems.
The filter's coating is another critical aspect of its performance. Both the front and back surfaces of the filter are coated with KNI 900DIJ, a coating specifically designed to enhance the filter's performance at the 900nm wavelength. The coating also contributes to the filter's overall durability and resistance to environmental factors.
The physical data of the filter includes the Center Wavelength (CWL) of 900nm, which is the central point of the filter's passband. This CWL is crucial in determining the filter's compatibility with different optical systems and light sources.
In terms of shape, the 900DIJ25 is a Thin Lens, a design that minimizes optical aberrations and enhances the filter's performance. This shape is particularly beneficial in applications where high optical precision is required.
