The 67-829 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter is a high-quality optical component designed for precise wavelength selection, sourced from the renowned vendor Edmund Optics. This filter is specifically designed for use at a central wavelength (CWL) of 380nm, with a full width at half maximum (FWHM) of 10nm.
The filter is circular in shape, with a diameter of 25mm and a thickness of 5.9mm, making it suitable for a wide range of optical applications. The base material of the filter is UVFS Mal-1965, a material known for its excellent optical properties.
The filter's coating is another notable feature. Both the front and back surfaces of the filter are coated with EDM 67-762, a proprietary coating developed by Edmund Optics for enhanced performance and durability. This coating helps to reduce reflections and increase transmission, improving the overall efficiency of the filter.
The physical data of the filter is also carefully controlled. The cut-on wavelength is 375nm, and the cut-off wavelength is 385nm, ensuring a narrow and precise bandpass. This makes the filter ideal for applications where precise wavelength selection is critical.
The filter is designed in a thin lens shape, which not only enhances its optical performance but also makes it easy to integrate into existing optical systems. The catalog number for this filter is 67-829, and it is currently in stock, ready for immediate shipping.
