65-221 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 568nm

The 65-221 is a Bandpass Filter, specifically designed with a diameter of 50 mm and a thickness of 3.5 mm. This filter, sourced from the reputable vendor Edmund Optics, is a crucial component for applications that require precise wavelength selection.

The filter's primary function is to allow light in a specific wavelength range to pass through while blocking out other wavelengths. In this case, the Cut-On wavelength is 563 nm, and the Cut-Off wavelength is 573 nm, with the Central Wavelength at 568 nm. This makes it ideal for applications that require a narrow band of light around the 568 nm wavelength.

The 65-221 is coated with EDM 65-099 on both the front and back, ensuring durability and optimal performance. The coating also enhances the filter's ability to withstand harsh environmental conditions, making it suitable for use in various settings.

This filter is designed in a Thin Lens shape, which is beneficial for applications that require a compact and lightweight optical setup. The filter's circular geometry further adds to its versatility, making it compatible with a wide range of optical systems.
