Steep Longpass Filters

Steep Longpass Filters
Steep Long Pass Filter (Steep Long Pass Filter) allows light with a wavelength greater than the set wavelength to pass through, and cuts off light with a wavelength smaller than the set wavelength.

Steep longpass filter standard products with diameters of 12.5mm and 25mm in packaged and unpackaged versions and wavelengths of 488nm-1064nm laser wavelengths. Due to the characteristics of steep transitions, it is widely used in microscopic imaging, Raman spectroscopy, biochemical analysis instruments, life sciences, education and scientific research and other related fields.
Precautions for use: Please wear finger cots when using, and do not directly touch the surface with your fingers, so as not to affect the light transmission effect due to residual fingerprints. If the surface of the filter is dirty, wipe the surface of the lens with dust-free lens cleaning paper dipped in alcohol. Do not wipe with a very rough cloth or paper or with water, otherwise the surface will be damaged.
