84-801 50 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 800nm

The 84-801 is a Bandpass Filter, specifically designed for use in optical systems requiring a narrow passband around the 800nm wavelength. Sourced from Edmund Optics, this filter boasts a circular shape with a diameter of 50mm and a thickness of 3.5mm, providing versatility and durability in various applications.

The filter is constructed from UVFS Mal-1965 material, ensuring high-quality performance. It features hard coating on both the front and back surfaces, denoted as EDM 84-777, which enhances its longevity and resistance to wear and tear. This coating also aids in reducing unwanted reflections, thereby improving overall system efficiency.

The 84-801 filter has a Cut-On wavelength of 775nm and a Cut-Off wavelength of 825nm, with a Central Wavelength (CWL) of 800nm. This precise wavelength control makes it ideal for applications demanding strict wavelength specificity, such as fluorescence microscopy, spectroscopy, and other laser-based systems.

The filter's geometry and physical data suggest that it is a Thin Lens type, indicating its potential use in focusing or collimating light paths. This feature, coupled with its 50mm diameter, makes it compatible with many optical systems and configurations.
