550DF40 18 mm Dia. Protected Coating; Bandpass Filter Protected Coating

The 550DF40 is a high-quality bandpass filter, measuring 18 mm in diameter and 3.5 mm in thickness, sourced from the reputable vendor, Omega Optical. This filter is designed to transmit light within a specific range of wavelengths, making it an essential component for various optical applications.

The filter's central wavelength (CWL) is 550 nm, positioned at the heart of the visible light spectrum. It features a protective coating on both the front and back surfaces, enhancing its durability and longevity. The protective coating also aids in reducing potential damage caused by environmental factors, ensuring optimal performance over time.

The 550DF40's cut-on wavelength is 530 nm, and the cut-off wavelength is 570 nm. This means that it allows light within the 530-570 nm range to pass through while blocking light outside this range. This specificity makes it an ideal choice for applications requiring precise wavelength selection.

The filter is designed in a thin lens shape, which not only contributes to its compactness but also minimizes optical aberrations. This feature makes it a versatile component, suitable for a wide range of optical systems.
