The 530FDL50 is a high-quality dichroic filter, measuring 50 x 50 mm, designed for longpass applications with a cut-on wavelength of 530nm. This filter is sourced from Knight Optical, a renowned vendor known for their extensive catalog of optical elements.
The filter is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high damage threshold. It has a thickness of 1.1mm, providing robustness and stability. The rectangular base shape allows for easy integration into various optical systems.
The 530FDL50 features a dichroic coating on both the front and back surfaces, identified as 'kni 530fdl-0'. This coating is designed to reflect or transmit light depending on the wavelength, making it ideal for longpass applications where light below the cut-on wavelength is to be rejected.
The physical data of the filter indicates a cut-on wavelength of 530nm and a cut-off wavelength of 0nm. This means that the filter starts transmitting light at 530nm and above, while completely blocking light below this wavelength.
The filter is available in a thin lens shape, which is advantageous for applications requiring minimal optical path length distortion. The 530FDL50 is currently in stock and available for immediate purchase through the vendor's website.
