Grand Unified Optics provides a standard product of high-performance dichroic filter with a diameter of 12.5mm and 25mm in packaged and unpackaged versions and a laser wavelength of 488nm-1064nm. The incident angle is 45°. The product has the characteristics of a steep transition from reflection to transmission, and the transition steepness is less than 1% of the laser wavelength. It is 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.
