Schneider-Kreuznach magnetron sputtered industrial shortpass filters impress with steep slopes and high transmission at stable cut-off wavelengths. The very flat surface makes them ideal for high end machine vision systems in factory automation. Schneider-Kreuznach shortpass filters are RoHS conform. Custom sizes are available on request. What is the function of a shortpass filter? A shortpass filter allows shorter wavelengths of light to pass through while blocking longer wavelengths. The filter is designed to transmit light that is below a specific wavelength cutoff, known as the filter's "cutoff wavelength," and to reflect or absorb light that is above this wavelength. Where is a shortpass filter used? In practical applications, shortpass filters can be used to remove unwanted longer wavelength light from a light source or to separate different wavelengths of light. For example, in fluorescence microscopy, a shortpass filter can be used to remove the excitation light and allow only the shorter wavelength fluorescence emission light to be imaged.
-> Average Transmission 95 %: Achieve an impressive average transmission rate of 95 % for optimal light throughput.
-> Steep slopes: Take advantage of steep slopes that allow efficient isolation of specific wavelengths.
-> Wavelength Tolerance +/- 1 %: Experience exceptional accuracy with a wavelength tolerance of +/- 1 %, ensuring precise results.
-> Ultra Low Reflection: They allow shorter wavelengths of light, minimizing reflections for ultra-low reflection in optical systems.
-> Deep Blocking / High Optical Density: Our bandpass filters offer deep blocking and high optical density, effectively minimizing unwanted light leakage.
