HPX470-40 25 mm Dia. Fluorescence Excitation Bandpass Filter 470nm
The HPX470-40 is a bandpass filter, specifically designed for fluorescence excitation, with a central wavelength of 470nm. This filter is manufactured by MKS/Newport, a leading vendor in the optical industry, and is available for purchase on their official website. The catalog number for this item is HPX470-40.
The HPX470-40 filter is circular in shape, with a diameter of 25mm and a thickness of 4.3mm. It is made from UVFS material, identified as MAL-1965. The filter's physical data includes a cut-on wavelength of 450nm and a cut-off wavelength of 490nm, making it ideal for applications that require narrow-band light transmission around the 470nm region.
The filter's coating is consistent on both the front and back surfaces, with a new HPX470-40 coating. This coating enhances the filter's performance, ensuring optimal light transmission and blocking unwanted wavelengths. The filter's shape is described as a thin lens, indicating its ability to focus or collimate light.
