84-799 50 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 700nm

The 84-799 is a Bandpass Filter, sourced from the reputable vendor Edmund Optics. This particular model boasts a 50 mm diameter and a thickness of 3.5 mm, making it a substantial yet manageable component for various optical applications.

The filter's primary function is to allow light transmission within a specific wavelength range while blocking light outside this range. The 84-799 is designed to pass light in the 700nm range, with a Cut-On wavelength of 675nm and a Cut-Off wavelength of 725nm. This precise wavelength selection is crucial for many optical systems, particularly in fields like spectroscopy, biomedical imaging, and machine vision.

The 84-799 features Hard Coating on both the front and back surfaces, enhancing its durability and resistance to wear and tear. This coating also reduces surface reflections, improving overall transmission and reducing unwanted scattered light.

The filter's geometry is defined by its circular shape and thin lens design, which contributes to its versatility and ease of integration into various optical setups. The material ID, uvfs mal- 1965, provides additional information about the filter's composition and manufacturing process.
