87-806 50 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 775nm

The 87-806 is a Bandpass Filter, specifically designed with a 50 mm diameter and a thickness of 3.5 mm. This filter, offered by Edmund Optics, is a part of their extensive catalog, known for its high-quality optical elements. The Bandpass Filter is a crucial component in various optical systems, allowing only a specific range of wavelengths to pass through while blocking others.

The 87-806 filter is designed to pass wavelengths around 775nm, with a Cut-On wavelength of 762.5nm and a Cut-Off wavelength of 787.5nm. This precise wavelength selection is essential for many applications, including fluorescence microscopy, spectroscopy, and laser technology.

The filter is made from UVFS Mal-1965, a material specifically chosen for its optical properties. It features hard coating on both the front and back, enhancing its durability and resistance to wear and tear. This coating, identified as EDM 87-782, is a high-quality coating known for its performance and reliability.

The filter's shape is defined as a Thin Lens, a common shape in optical elements due to its minimal thickness and weight. This makes it an ideal choice for applications where space and weight are critical factors.
