87-802 50 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 575nm

The 87-802 is a Bandpass Filter, specifically designed for use in optical systems that require a narrow passband. This filter, sourced from Edmund Optics, boasts a 50 mm diameter and a thickness of 3.5 mm, making it suitable for a wide range of applications.

The filter's primary function is to transmit light within a specific wavelength range, while blocking light at other wavelengths. In this case, the 87-802 has a Cut-On wavelength of 562.5 nm and a Cut-Off wavelength of 587.5 nm, with a Central Wavelength (CWL) of 575 nm. This means it allows light around the 575 nm wavelength to pass through while blocking light outside this range.

The 87-802 features a Hard Coated OD 4.0 surface, which provides excellent durability and resistance to environmental factors. The coating also enhances the filter's performance by reducing unwanted reflections and increasing transmission.

This filter is designed with a Thin Lens shape, which allows it to be easily integrated into various optical systems. It is made from UVFS Mal-1965 material, ensuring high-quality performance and reliability.
