87-805 50 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 725nm
The 87-805 is a Bandpass Filter, specifically designed for applications requiring precise wavelength selection. 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 optical systems.
The filter's primary function is to transmit light within a specific range of wavelengths while blocking other wavelengths. In this case, the Cut-On wavelength is 712.5 nm, and the Cut-Off wavelength is 737.5 nm, with a Central Wavelength (CWL) of 725 nm. This makes it ideal for applications that require the transmission of light around this wavelength.
The 87-805 is coated with EDM 87-781 on both the front and back surfaces, enhancing its performance and durability. This hard coating provides improved resistance to environmental factors, ensuring the filter maintains its performance over time.
The filter's geometry, with a diameter of 50 mm and a thickness of 3.5 mm, is designed to balance between compactness and robustness. This makes it suitable for various optical systems, from compact setups to more complex configurations.
