515FDC50 50 x 50 mm Bandpass Dichroic Filter 515nm

The 515FDC50 is a high-quality dichroic filter, measuring 50 x 50 mm, designed for optimal performance at a central wavelength of 515nm. This filter is sourced from Knight Optical, a renowned vendor known for their precision optical components.

The filter is a rectangular dichroic filter, designed to selectively transmit light within a specific wavelength range while reflecting unwanted wavelengths. In this case, the 515FDC50 has a passband between 500nm and 530nm, making it ideal for applications that require narrow-band transmission around the 515nm wavelength.

The filter is made from N-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties. It has a thickness of 1.1mm, providing robustness and durability while maintaining high optical performance.

The front and back surfaces of the filter are coated with the KNI 515FDc-0 coating, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance, ensuring high transmission within the passband and high reflection outside of it.

The filter is shaped as a thin lens, which can be beneficial in certain optical systems where a lens-like element is required. This filter is currently in stock and available for immediate purchase through the provided weblink.
