HPM685-50 25 mm Dia. Fluorescence Emission Bandpass Filter 685nm
The HPM685-50 is a Bandpass Filter, specifically designed for fluorescence emission, with a central wavelength of 685nm. This filter is manufactured by MKS/Newport, a renowned vendor in the optical industry. The filter is circular in shape, with a diameter of 25mm and a thickness of 3.5mm, making it suitable for a wide range of optical applications.
The HPM685-50 filter is designed to transmit light within a specific wavelength range, while blocking other wavelengths. The cut-on wavelength is 660nm, and the cut-off wavelength is 710nm, ensuring a tight bandpass. The central wavelength (CWL) of the filter is 685nm, providing a high transmission rate for light within this wavelength.
The filter is coated with a new HPM685-50 coating on both the front and back surfaces, enhancing its performance and durability. The shape of the filter is thin lens, which is beneficial for applications requiring minimal optical path length distortion.
The filter is currently in stock and available for purchase on the MKS/Newport website. For more information, users can visit the provided weblink: https://www.newport.com/p/HPM685-50.
