At540-30M C 25 mm Dia. Sputter Hard Coated; Bandpass Filter

The At540-30M is a Bandpass Filter offered by Chroma, a leading vendor in the optical industry. This filter, with the catalog number At540-30M, is available for purchase and is currently in stock. The filter is primarily characterized by its wavelength of 540 nm and circular geometry with a diameter of 25 mm and a thickness of 1 mm.

The Bandpass Filter is a type of optical filter that allows only a specific range of wavelengths to pass through it while blocking others. In this case, the At540-30M has a cut-on wavelength of 525 nm and a cut-off wavelength of 555 nm, making it highly effective in transmitting light within this narrow band. The central wavelength (CWL) of this filter is also 540 nm, which is the wavelength at which the filter has its maximum transmittance.

The At540-30M is coated with a Sputter Hard Coat on both the front and back surfaces. This coating enhances the durability and performance of the filter, ensuring it can withstand rigorous use and maintain its optical properties. The shape of the filter is a Thin Lens, which is often used in optical systems to focus or diverge light.
