Grand Unified Optics provides two versions of 12.5mm and 25mm packaged and unpackaged steep long-pass filter standards with a wavelength of 488nm-1064nm laser wavelength. The filter has a high laser damage threshold, The characteristics of deep cut-off depth and steep transition from reflection to transmission are widely used in microscopic imaging, Raman spectroscopy, biochemical analysis instruments, life sciences, education and scientific research and other related fields. We can also offer custom coatings according to your requirements.
